7 September 2017 - Gothic Browns

Feathered Gothic (Tholera decimalis)

An intricately patterned moth is the Feathered Gothic, with its strings of white on a delicate, brown ground colour.  The broad antennae give it the appearance of being tuned in to information sources about which we know not a thing.
The moth scatters its eggs over grassland and the eggs remain dormant over winter - like the Swift moths do.  When the caterpillars hatch they feed at night on hard-bladed grasses.
The moth is common but not often seen unless caught when it comes to light. 

Dark Sword-grass (Agrotis ipsilon)

Another moth seen only once before in the garden at Shandy Hall  - the Dark Sword-grass. This one was in excellent condition.  It is an immigrant moth and it hasn't been confirmed that it ever breeds in this country.  It will come to light traps and can be seen in almost every month of the year especially on the coast.

Square-spot Rustic (Xestia xanthographa))
None of these three moths is new but they each reflect the fact that Summer is coming to an end. Dark browns and soft browns combine to aid camouflage as the apples ripen and the leaves turn.  The Square-spot Rustic is flying in numbers at the moment.  This one just looked particularly perfect.  

Looking at the list of moths that should be active during this month I see that the Chevron (Eulithis testata) is not uncommon and is yet to be seen in Coxwold.  An objective then...

29 August 2017 - The Typo Moth

Leopard Moth (Zeuzera pyrina)
Such a striking moth is the Leopard (Zeuzara pyrina).  This is only the second time that this species has been seen in the garden.  As the pupa overwinters, sometimes for two or three years, it is possible that the eggs laid by the previous Leopard (in 2012) have hatched, pupated and transformed into the flying adult that came to the trap last night.  The moth was found outside the trap on the white sheet - as was the first recorded.  Perhaps the distinctive colouring acts as a warning to predators

The moth's legs terminate in very 'sticky' feet and when disturbed it curls up, slumps and appears to be dead.  It took some time before it could be persuaded to cling onto a leaf and then be carried to an apple branch and photographed.  An apple or pear tree is the home of the caterpillar for the majority of its life. The adult does not feed.

The scientific name is a typographical error.  The binomial should have begun with 'zenzura', the Italian name for a gnat, from zenzero (ginger) referring to the sharpness of the gnat's bite and the pupa's jaws - this caterpillar tunnels through branches. P. A. Latreille, a distinguished French entomologist, gave the species the name but either the printer or the expert himself failed to spot the typo.  My bet is on the printer.

Leopard Moth (illustration)

Wonder of wonders a Red Underwing was also in the trap.  A fine, recently hatched creature that was as impatient and edgy as every other one I have ever seen.  Getting a decent image of its glorious red hindwings might have lead to its escape and I was concerned that it would just get snapped up by one of the numerous birds that gather around the trap.  The flycatchers have now gone but there are plenty of other species happy to get breakfast on a plate.

The Red Underwing (Catolcala nupta) 'the bride with beauty beneath' refers to the brightly coloured petticoats (hindwings) that Linnaeus seems to be describing.   The photograph doesn't give a clear enough impression as to how big this moth is, but if you see one (and this is only the third I have seen in North Yorkshire in six years), you will be surprised. 

Red Underwing (Catocala nupta)

The hand-coloured image does the moth justice.  The depth of colour is accurate.
Red Underwing (illustration)

The last species to be recorded is one that hasn't been seen for a long time - the Iron Prominent (Notodonta dromedarius).

Iron Prominent (Notodonta dromedarius)
The Prominents are members of the Notodontidae family and some are the best camouflaged moths we have in this country.  They tend to have long tapering wings which fit closely around the abdomen and the males have feathered antennae.  The Iron Prominent photographed is not in the best condition but splashes of rust colour can be seen relatively easily.  None of the Prominents feed as adults but all tend to come to light.

23 August 2017 - China and Gold

Small China-mark (Cataclysta lemnata)
A new species to Shandy Hall - but not to the blog.  How can this be?  

A moth trap was set in Luddington-in-the-Brook in 2015, in the garden where the artist Carry Akroyd* lives.  Even before I  had set up all the paraphernalia that seems to go with identifying and recording moths, and before night had fallen, I noticed two or three insects drifting gently over Carry's lawn close to a small pond.  Small China-mark (Cataclysta lemnata) was the name that sprang to mind, and the reason they were there was the pond - the place where the moth's larva spends some of its time.  Or so I had read.  There was the mothy proof.

I hoped that one might be seen at Shandy Hall one day and, two years later, it has arrived - species number 422.

The pond that we managed to dig in the quarry (a few years ago now and thanks to kind volunteer help) is now full of newts. It must also be a shelter for the Small China-mark's cocoon - constructed using duckweed floating on the water.  The Small China-mark was a bonus for what turned out to be a rain-drenched night in North Yorkshire.

Triangle Plume Moth (Platyptilia orthodactyla)

The forecast hadn't looked too bad, just a little rain at around 7pm and then cloudy and warm. It threw it down. When I went to switch off the mercury vapour light this morning, I could see immediately that the cloudiness and warmth had attracted over two hundred Underwing (of different species) and around a hundred Straw Dot (Rivula sericealis).  The underwing invasion is (thankfully for the planetary food-chain) predictable, but I haven't seen so many Straw Dot moths before and I don't know why there should be so many.  What else was to be found in this swirling mass of fluttering? 

A couple of Gold Spot (Plusia festucae), a Gold Triangle (Hypsopygia costalis), dozens of Flame Shoulder (Ochropleura plecta), a Double-Striped Tabby and a Plume. It is always cheering to see a Plume as they seem to represent everything that is magical about moths. But which species is this one? We have had a Brown Plume, a White Plume, an Emmelina monodactyla, and a Beautiful Plume.  Is this one new to the garden?  It seems larger than the Beautiful Plume and the others in the 'family' that could qualify are all far too scarce to turn up in Coxwold. If you click on the photograph it will show you the moth in a little more detail.  I sent a photograph to Charlie Fletcher in the hope that he would identify it and he confirmed that it was a Triangle Plume (Platyptsilia orthodactlya) - wide-winged and of the colour ochre (platus ptilon okhra).

According to the website Yorkshire Moths Flying Tonight (a helpful resource) this moth is 'uncommon and thinly distributed' in the county, so it is especially pleasing to have recorded it in Coxwold.  The moth has Coltsfoot (Tussilago farfara) as the food plant - a plant that I haven't seen for years and one that we don't have in the gardens.  The scientific name refers to its use as a cure for a cough (L. tussis).

The Triangle Plume is species number 423.

Gold Spot (Plusia festucae)

A regular visitor in the later days of August is the Gold Spot.  The wings are decorated with gold and silver flashes and it is very easy to identify.  There is a variant - Lempke's Gold Spot - which we have recorded as well.

Gold Triangle (Hypsopygia costalis)

The little Gold Triangle (Hypsopygia costalis) is in its initial resting position in the photograph.  When fully at rest the fore-wings and hind-wings are spread out and the abdomen is slightly lifted : hupsos meaning 'height' and pugaios meaning 'pertaining to the rump'.

What else?  An Angle Shades, Gothic, Dark Arches and sexton beetles, wasps, ichneumon flies, caddis flies, those little beetles that look like moving rabbit droppings, shield bugs, mosquitoes, lace wings, ground beetles and a variety of different crane flies.

15 August 2017 - Magical Circle of Moths

Magpie moth (Abraxas grossulariata) in variety
A strange similarity to the last blog. Three moths of the same species beautifully illustrated by Henry Noel Humphreys once again, but this time they are Magpie moths and their circle might be easily conceived as magical. Abraxas is a Coptic word coined by the Gnostic teacher Basilides.  He wished the word to represent the number 365 - the number of days in the year.  Gem stones were inscribed with the magical word together with images of entwined human and animal forms. The word Abracadabra, the conjuror's word is from the same root. The arrangement in the image seems appropriate.  
The three moths show examples of the variations of pattern on the wings of the Magpie moth - the photograph below is the one that was lured by the mercury vapour lamp.

Magpie Moth (Abraxas grossulariata)
The second half of the binomial refers to the thorny plant beneath - the gooseberry.  This little plant is growing close to a stone wall and is, I think, the only example in the garden. There is no sign of caterpillar activity on the leaves so this moth must have flown in from a neighbouring garden.

Not the best of images but I was lucky to get one at all as this moth rushes back and forth in a very animated state.  The Honeysuckle Moth (Ypsolopha dentella) with the tooth-like shape to the wings when at rest.  Ypsolopha means 'high crested' and the food plant is honeysuckle. 

Honeysuckle Moth (Ypsolopha dentella)

Honeysuckle Moth illustration
The little hooks on the end of the fore-wings (seen in the illustration), form the 'dentella' that can be seen in the photograph of the moth on a rose stem.  Rather wonderful in its own way. 

10 August 2017 - Ring a Ring a Rustic

Common Rustic (Mesapamea agg)  in variety

The trap was set on Wednesday night with high expectations (no rain!), but there was a definite chill in the air. This is supposed to be the height of Summer so surely there would be a wide variety of species despite the drop in temperature.  Sadly it was not to be.  A Common Wainscot, Lesser Broad-bordered Underwing, Large Yellow Underwing and three Common Rustic moths was the sum total of the catch.

The Common Rustics displayed their varieties and the three were remarkably similar to the ones drawn and painted above (British Moths and their Transformations, Humphreys and Westwood. 1843).   
The description that accompanies this illustration is a veritable flourish of scientific description : 
In some specimens (Fig. 8) they are nearly of a uniform mouse-brown colour, with the slightest indication of the strigae.  In others (Fig. 9) they are of a rich dark chocolate brown, and shining, with still less distinct traces of the strigae, except the wings be held in a certain position, when they may be perceived of a duller hue than the rest of the wings; whilst some (Fig. 7) have the fore wings much varied along the inner margin, and beyond the posterior stigma with a pale luteous buff.  In almost all these varieties the posterior stigma is more or less distinct and accompanied by a white dot and the undulating subapical striga is succeeded by a darker tinge, forming an irregular margin along the apex of the wing.
[The striga referred to seems to mean the presence of a 'furrow'.  I can't find a more appropriate definition.]

Common Rustic (Mesapamea agg)
It is now firmly established in the world of moths that there are three varieties of Common Rustics and, as they cannot be reliably identified, they have to be recorded as Mesapamea agg.  One food plant of this busy little moth is the buddleia (see above) which is still in full flower in the garden.

3 August 2017 - New Moth as Farewell

(Acleris aspersana)

Despite the ominous clouds and rain, my last moth trap yielded amazing results. The number of moths increased immensely compared to the past few traps and the number of species rose as well. No matter the outcome, I would have been excited and grateful either way. In fact, there has never been a day during these past two months where I was not looking forward to working on moths.

The Ginger Button (Acleris aspersana) had me especially ecstatic. I will admit, not finding any new moths created some disappointment, but finding this one has eradicated all those feelings. When first spotted, I thought it was probably another worn tortrix moth that I had already seen before. However, I decided to capture it as there was a sense of unfamiliarity. This turned out to be a lucky decision. Compared to other members of the Acleris genus, Acleris aspersana is smaller in size. It likes grasslands and heaths and is common nationally but scarce locally. Its scientific name aspersana means ‘sprinkled’, which describe the several variations of patterns the moth might have. Some may have patterns resembling netting and linear lines.

The larvae of the Ginger Button live inside the rolled leaves of various herbaceous plants. Some of these include the European Crab Apple, Cinquefoil, Blackberries, Strawberries, Burnet, Meadowsweet, and Goat’s Beard. There’s some Goat’s Beard (Spiraea aruncus) in our garden which might be the origin of our tiny moth but the meadowsweet is a possibility too - the quarry is full of it.

Meadowsweet (Filipendula ulmaria)

A new species to Shandy Hall, Acleris aspersana is moth number 421! A great way to end my journey here in England.

Acleris aspersana (2 male, 3 femalewith Campion

I just wanted to mention how grateful I am for this opportunity. Despite studying computer science, growing up, I have dreamed of being a zoologist. While I didn’t get to explore the Amazon rainforest searching for reptiles and amphibians, this experience has allowed me to tap into my inner love for animals and help fulfill a dream of mine. Maybe I’ll even become a lepidopterist in the future. I also wanted to thank everyone I have met throughout my time here at Shandy Hall. All the workers and volunteers have been amazing and I will truly miss this wonderful place.

28 July 2017 - Heralding the End

Phoenix (Eulithis prunata)

I started this internship with rain and the forecast tells me I will probably end with it as well. There’s still a few more days left so hopefully I can get in another moth trap before my departure. The past few traps have unfortunately been disappointing. The number of moths has decreased and subsequently the number of species. I believe it might be due to the change in the weather. 

The Phoenix (Eulithis prunata) arrived in our trap set on Tuesday night. The moth was upside down when I first saw it so I didn’t know what it was. I took one of our jars used for larger moths and carefully captured it. As it flew into the jar it quickly attached itself to the side of the container and slowly lifted its tail, creating a 90-degree curve.

Phoenix (illustration)
Eulithis meaning ‘goodly stone’, refers to the species of this genus having a yellowish color similar to sandstone, while prunata makes reference to the plum fruit although in Britain, it is not the food plant for the larvae.

Redcurrant fruit
The larvae of the Phoenix feed on blackcurrant (Ribes nigrum) and redcurrant (Ribes rubrum) which is in abundance just outside the kitchen window of my flat. As I write this the redcurrants are currently ripening and are quickly being devoured by birds.

The Herald (Scoliopteryx libatrix)

Bringing the rain with it, the Herald (Scoliopteryx libatrix) made an appearance in the trap. Its shape and pattern makes it seem to belong in a fantasy novel. The longitudinal red streaks shine and look like embers emanating from its wings. Its scientific name, Scoliopteryx, means ‘crooked wing’ which is a description of the curvy edge of the wings. 

The second half, libatrix, means ‘one who makes a libation to the gods’. There is no explanation to the reasoning behind this name but one theory states Linnaeus might have thought the naming of the Herald deserved a drink. Interestingly, the Herald overwinters as an adult and can be found hibernating in barns and caves. 

The Herald (Scolopteryx libatrix)

Larvae of Scolopteryx libatrix feed on Willow (Salix) and Poplar (Populus). In our quarry, we do have a White Poplar (Populus alba) which can be easily distinguished when compared with other trees as its leaves are white and grey. It may even appear to be covered in snow when viewed from a distance.

White Poplar (Populus alba) 

22 July 2017 - Slender Footman

Slender Footman (Eilema complana)

Before opening the moth trap we scanned the interior of the tent, looking for any moths hiding inside the crevices or folds of the fabric. Usually when the tent is set up, there will mostly be a population of Common Footman and Mottled Rustics to be found. This time was similar, but added to by Chinese Characters as well. As we flipped the tent to its side however, I spotted a skinnier than normal footman resting next to the zipper. We put it in a tube and decided to head back inside as the rain had started t come down harder. 

Identifying the few moths caught from the tent alone, things seemed hopeful as the footman turned out to be a Scarce Footman (Eilema complana). Its coloration is overall appearance is similar to the Common Footman, but unlike its cousin, the Scarce Footman's wings are curled up around its body when at rest. Like its name suggests, the moth is uncommon and resides mainly in the south and east of England, preferring moorland and coastal areas. Recently, it has been gradually moving to the North and West. Charlie Fletcher tells us that our record extends its range by five miles! 

Eilema means ‘a veil’, which describes the wrapping of the wings around the abdomen. The second part complana means ‘to make level’.  This part of the binomial has a complicated derivation as it also refers to the position of the wings when the moth is at rest.

The larvae of the Scarce Footman, like many others of the family, feed on lichen which is plentiful here at Shandy Hall.

Water Veneer (Acentria ephemerella)

A Water Veneer (Acentria ephemerella) was also found fluttering around in the bottom of the tent. Moths are usually inactive in the morning so I had some doubt whether it was actually a moth or not. It has been recorded at Shandy Hall but not photographed before. I predicted it to be difficult to photograph as the moth was not keen on remaining still. To my surprise, the Water Veneer stayed motionless on the leaf I placed it on allowing me to get a detailed photograph of it.

The moth's lifestyle is extraordinary compared to other moths as it lives around ponds and slow-moving water. The females can either have wings or not, the ones without living underwater. The males have wings and will mate with females on the surface of the water. The larvae are aquatic and feed on the several varieties of pondweed (Potomogeton sp.). We have a small pond located in our quarry right next to an oak tree. This pond, despite its size, holds a diverse ecosystem of newts, insects, and plants.

(Opostega salaciella)

Finding these species in the tent had me excited for the moth trap which remained unopened. The egg boxes turned out to be covered in species I have never seen before, one of which was the Opostega salaciella. Another uncommon moth, Opostega salaciella is the only moth in its family that is completely white. Its large eye caps, which can be seen in the photograph, open as it moves along. Unsurprisingly, Opostega means ‘face roof’, which derived from the large eye caps. The second half salaciella means ‘lustful’, which is thought to have come from its flight patterns around its foodplant being delightful.

Not much is known about the early stages of the moth but it is guessed that the larvae feed on Sheep’s Sorrel (Rumex acetosella). We do not have any Sheep’s Sorrel here in Shandy Hall but we do have a species of sorrel in a small pot.

Both the Scarce Footman and Opostega salaciella are new to Shandy Hall. Our count rises by 2 which means we have reached 420 species for the two acre plot.

20 July 2017 - Fungus Feeder

(Crassa unitella)

The moths trapped on Monday night were less active than on the previous occasion, but the diversity stayed the same. I was also greeted by a few wasps in the trap. Whether there is a wasp nest nearby or they just decided to take a late-night stroll, I’m not sure. Frankly, I was less worried about where they came from and instead, focused on getting them out of the trap before I got stung. Most of them flew out when I opened the lid while one needed some persuasion with the trusty paint-brush. With the danger removed, I could start identifying moths.

The Golden-brown Tubic (Crassa unitella) was found on the side of an eggbox. At first, I was unsure if it was even a moth because it resembled the shape and coloration of a caddis fly. I decided to put it in an inspection tube after seeing the elongated palps, which are the upwards curling parts near the moth’s mouth. It’s bright yellow head is very noticeable compared to its dark wings. The moth is reported as being scare in Yorkshire but it is common in southern England. 

Crassa unitella is also known as Batia unitella in some books. Batia is ‘a thorn-bush’, while unitella means ‘unity’, which describes the singular color on the wings.

The larvae of Crassa unitella feed on fungus found on or under dead tree bark.

(Blastobasis lacticolella)

The London Dowd (Blastobasis lacticolella) also made an appearance in the trap. Its markings vary, some being heavily marked and others with no markings at all. A common species, it is not actually native to Britain and was introduced around 1946. The London Dowd is native to the Portuguese archipelago, Madeira. Being a year-round resort, there’s quite a contrast when comparing the two environments - the moth has adapted well to the drastic change.

The larva of Blastobasis lacticolella feeds on leaf-litter, vegetation, and it has also been reported eating dead insects.

A new species to Shandy Hall, Blastobasis lacticolella bumps the number of different species up to 418!

18 July 2017 - Fruit Lover in Frenzy

Large Fruit-tree Tortrix (Archips podana)
I woke up Sunday morning to find a frenzy of moths fluttering about in the trap. Moths are usually docile and like staying still on the egg-boxes, (apart from the Yellow Underwings that just like to crawl all over everything) but on this occasion most were actively flying around.  This caused a chain reaction as they barged into other moths. The most hectic of the bunch were still the Yellow Underwings, but Mother of Pearls and Garden Grass Veneers also partook in the hysteria.

It was necessary for Patrick and I to go through the trap together, as having another pair of eyes helps us not to miss any that fly away.  However, we were still no match for the plethora of moths covering the interior. While I believe we got most of the moths we were uncertain about and identified many of the others, there were still some that managed to evade our line of sight. We estimated around 400 moths were caught and there were 53 different species I managed to record.

The Large Fruit-tree Tortrix (Archips podana) was one that stood out. I immediately recognized it as a tortrix but it was huge compared to the other species in the family Tortricidae. I had never really considered the sizes of micro moths until now and the variety still amazes me. This one was easy to distinguish as it is larger than most and its pattern is quite simple to recognise.   Archips podana is sexually dimorphic, which means the male has a different pattern on the fore-wings than the female. The one we have is a male as it’s more colorful and the tip of its wings do not curve upwards so much. Its name Archips describes ‘a worm or larvae that eats vine-buds’; the larvae are also pests to some fruit trees. 

The other half of the binomial is podana which is named after the Austrian physicist and entomologist Nikolaus Poda von Neuhaus.  Neuhaus was primarily focused on physics and mathematics and became a professor of such subjects, but later created a natural history collection which included insects.

Apple Tree (unknown variety)
The larvae of the Large Fruit-tree Tortrix, like its name suggests, feed on the foliage, flowers, and fruit of deciduous trees like apple and plum. We have a couple of fruit trees in our garden including a Keswick Codlin apple tree which is appreciated for its early production in the season and its effectiveness for making a sweet puree.

17 July 2017 - Bright-eye

Brown-line Bright-eye (Mythimna conigera)

After a break of several years, a Brown-line Bright-eye (Mythimna conigera) has finally returned to visit Shandy Hall. It was last recorded before the blog was created so no photographs had been taken. Mythimna conigera was a welcome change from looking at the several varieties of rustic moths, as the bold, clear patterns really popped out in contrast to the light brown wings. The white 'tear-drops', one on each wing, almost shine when observed and is probably the reason for its vernacular name. This moth shouldn’t however, be confused with the more common Bright-line Brown-eye (Lacanobia oleracea). Although they look different, I find myself sometimes switching the two names with each other. It might make for a fun tongue- twister, saying the two names together five times fast.

In the same genus as the many members of the wainscot family, Mythimna is a town on the island of Lesbos. Conus, meaning a cone, and gero, meaning to carry, describe the white spots on its wing which may be in the shape of a cone.

The nocturnal larvae feed on grasses including cock’s-foot (Dactylis glomerate) and common couch (Elymus repens).

13 July 2017 - Nests as Nourishment

Scalloped Oak (Crocallis elinguaria)

Seeing the number of moths caught beginning to decrease, we decided to change the location and set the trap in the quarry instead. The next morning, after I had collected the trap, I was ready to see what was inside the egg boxes. Then it started to rain, so I decided to shelter the trap in the arcade while I stood underneath the yew tree. It turns out that the yew provides little protection from the rain, probably because the leaves are needle shaped. I decided to wait for the rain to stop, which took most of the day. When it did finally stop the temperature dropped which made going through the trap quite the experience. 
We definitely did get more moths in the trap, but there was not a huge variety in the species. 

The Scalloped Oak (Crocallis elinguaria) appeared in our trap for the first time since I arrived. Its markings are intense and the two dots stared back at me like eyes. It is a common species which flies from Europe to eastern Siberia. Crocallis comes from the Greek words krokos and kallos, the former meaning the color of turmeric and the latter meaning beauty. The other half of the scientific name means ‘speechless’ or ‘without a tongue’ - the Scalloped Oak moth does not feed.

However the larvae of the Scalloped Oak have few restrictions when it comes to feeding. Deciduous trees and shrubs make up the majority of their diet. Some examples found in our quarry are oak (Quercus) and honeysuckle (Lonicera). They can even be cannibalistic, eating smaller larvae.

Double-striped Tabby (Orthopygia glaucinalis)

A Double Striped Tabby (Orthopygia glaucinalis) was discovered not in this trap but the previous one. I thought nothing of it as it was considered common nationally. It wasn’t until I was told this was only the second sighting of the moth in the garden in Coxwold that I realized it was uncommon in our specific area. Native to Europe, this moth stays true to its name by having two stripes which can look similar to those on a tabby cat. 
Its name Orthopygia means ‘straight’, describing the position of its abdomen when at rest. Sometimes it is placed in the genus Hypsopygia which means ‘height’, due to species of this genus having an upwards facing abdomen when at rest. The other part of its binomial glaucinalis means ‘blueish grey’, which is the color of its wings.

Double-striped Tabby (illustration)

Interestingly, Orthopygia glaucinalis can be seen flying near haystacks and thatches. Their larvae subsequently feed on such items and might also eat other dry vegetable matter such as birds’ nests. Throughout Shandy Hall, one can find birds’ nests of all kinds. There are some in the gutter, in the barn, and there’s even a thrush nest right outside my flat.  The photograph shows the nest the Spotted Flycatcher has used this year, so this might now be useful for the Tabby.

12 July 2017 - Ghosts Gathering

Ghost Moth (Hepialis humuli humuli)

The trap we set out in the garden did not have as big of a yield as we had hoped. While the species number was low, there was still an interesting collection.

This female Ghost Moth (Hepialus humuli) was a surprise to me, as it camouflaged perfectly with the lemon-sorbet colored egg box. The Ghost Moth is a dimorphic species which means that the male has a different pattern from the female. One of the five primitive moth species here in the British Isles, the males form a lek, which is a gathering of males who perform competitive displays to attract mates. Its distinctive flight, usually at dusk and after dark, is comparable to a pendulum and during which, they release a ‘goat-like’ scent. Once the larvae hatch they go underground where they feed on the roots of grasses and herbaceous plants for two years.  Dock and nettle are both on their menu.

Its name Hepialus means ‘a fever’, which describes its pendulous flight motion, and humuli means ‘the hop genus’, which was the food plant that the larvae were thought to feed on. Ghost moths can be seen gathering on the verges of the road from Coxwold to Kilburn, just a few hundred yards from the garden.

Coxcomb Prominent (Ptilodon capucina)

Another striking moth in our trap was the Coxcomb Prominent (Ptilodon capucina). Hidden in a shadow in the moth trap, it was right next to a Beautiful Golden Y (Autographa pulchrina). I thought the two moths were the same species as I went to gently lift the moth out of the trap, but as the light slowly illuminated the body of the moth I realized how different the two were. This burnt umber colored moth has a unique characteristic located on the top of its head. Its shark-like fin, when looked top-down, is a bright buff color. It reminded me of the wood planks carpenters use for their woodworking projects.

Its scientific name Ptilodon means ‘a tooth’, referring to the dorsal tuft on the forewing, and capucina means ‘a cap’, describing the prominent crest on its thorax. The larvae of the Coxcomb Prominent feed on a number of deciduous trees such as lime, apple, poplar, and oak.

(Zeiraphera ratzburgiana)

The Spruce Bud Moth (Zeiraphera ratzeburgiana) was also found in our trap. At first glance, the moth seemed familiar with its central crest on its wings. However, I did not recall seeing many tortrix species with that color before so I placed it in a tube to help make an identification.

(Z ratzburgiana) 
Zeiraphera ratzeburgiana was not difficult to locate in the micro moths guide book as its coloring was different from the many shades of grey found on the other moths. Zeiraphera means ‘a loose garment’, which might relate to the larval spinnings of the caterpillars. The second half of the name ratzeburgiana is named after the German entomologist, Julius Theodor Christian Ratzeburg.

Yew branch with berries
Like the name suggests, the Spruce Bud Moth does feed on spruce, but it also feeds on the shoots of a variety of coniferous trees. We were quite confused to start with because we could not think of any coniferous trees near us. It turns out that the Yew in our garden is a conifer even though it does not produce any cones, just seeds wrapped in red fruit.

Zeiraphera ratzeburgiana is a another new species for Shandy Hall which makes the count 417!

10 July 2017 - A Leaf Miner

Swallow-tailed Moth (Ourapteryx sambucaria)

The traps are starting to attract more diverse species. The many moths caught are looking more colorful and vibrant.

One of the moths trapped was the Swallow-tailed moth (Ourapteryx sambucaria). It’s a common species throughout Britain, besides northern Scotland, but they only fly for a short period in July. Its scientific name, Ourapteryx, describes its wings as oura means ‘tail’ and pterux means ‘wing’. The second half of the binomial, sambucaria, means ‘elder’ - the foodplant as described by Linnaeus. The Swallow-tailed moth however, does also feed on other trees and shrubs such as Hawthorn and Blackthorn, but it prefers ivy (Hedera helix).
Shandy Hall gardens has had Swallow-tailed moths before, but we were unable to get a good photograph until now as the moth is eager to fly at the slightest disturbance.  This one stayed still for just long enough.

(Phyllonorycter sp.)
This Phyllonorycter sp. was another moth found in our trap. At first, I believed it was a Phyllonorycter oxyacanthae as it was the only similar looking Phyllonorycter species on the Yorkshire Moths Flying Tonight website. However, that was not enough to validate my assumption because there is a plethora of Phyllonorycter species which look very similar. The best way to determine the correct species (apparently) is to look for the leaf mines of the larvae - little pathways just under the surface of a leaf.  Its name Phyllonorycter is appropriate as it means ‘leaf miner’.

(Aleimaa loeflingiana)

The Yellow Oak Button (Aleimma loeflingiana) was also in our trap. It can be difficult to recognize Aleimma loeflingiana due to its variety of patterns. Aleimma means ‘oil’ which was named after the forewing patterns which look as if they have been smudged. 
The Swedish botanist Pehr Löfling has his name woven into the second part of the scientific name. Löfling was a student of Linnaeus at university and he was chosen to serve as a botanist in the American colonies. 

The larvae of Aleimaa loeflingiana feed on oak (Quercus). The Yellow Oak Button is also a new species to Shandy Hall which bumps the number up to 416!
