Yardley Chase

I ran a couple of MV traps in the very far north of Bucks last night, my first trapping visit to a wood that doesn't ever seem to have been surveyed for its moths.  It is very nice mixed woodland, a part of the Forestry Commission's Yardley Chase complex of which most lies across the border in Northamptonshire.  With some half-decent weather at last, I was expecting a reasonable return in the usual three hour session and I wasn't disappointed, getting about 50 species altogether.  There was nothing overly exciting, only a few micros and overall numbers of everything were quite low, but it was just nice to get a decent variety of moths for the first time this year.

Flame Carpet, Yardley Chase 30th April

Dwarf Pug, Yardley Chase 30th April

Seraphim, Yardley Chase 30th April

Scalloped Hazel, Yardley Chase 30th April

The above five species were first sightings for me this year, the Flame Carpet being a rather dark example.  Other new ones were Pseudoswammerdamia combinella, Zelleria hepariella, Clouded Border, Waved Umber & Puss Moth (a surprisingly battered female who had obviously been out partying the night before - a significant contrast to the pristine male I had in the garden trap the same night!).

More Pugs

Two pugs in the trap this morning. I think that one is a Currant Pug, but I'm not sure about the other. Any suggestions?

Thanks, David

Currant Pug?

Any ideas on these two from this morning?

Could the first (on green) be an Oak Tree Pug?

Much appreciated

Poplar Kitten and Semioscopis steinkellneriana

A warmer night produced 10 species to my 40W actinic. An even better result in having two moths noted as Local to the area. Poplar Kitten is added to my favourites list and I'll release it back to the nearby aspens. Not shown here but it did have feathered antennae and FW was 20mm. Semioscopis steinkellneriana I thought was a miniature Hebrew Character at 10mm FW. Plenty of blackthorn opposite for its larvae.

Silver Cloud

 Having not caught one last year I was pleased to catch a Silver Cloud last night. I think I must be right at the edge of their range as I know people trapping in the Avon Valley have been reporting them regularly over the last couple of weeks.

Further recent arrivals for the 2022 garden moth list have included Spectacle (19th), V-Pug (20th), Cnephasia sp, Eudonia angustea, Green Carpet, Turnip Moth & Flame Shoulder (all 22nd), Common Pug & Pebble Prominent (both 23rd), Scrobipalpa acuminatella & Knot Grass (both 24th), Parornix sp (26th), Treble Lines (27th) and White Ermine (28th).  The Cnephasia and Parornix await determination by dissection but the first appearances here are usually of communana and anglicella respectively.

Cnephasia sp., Westcott 22nd April

Green Carpet, Westcott 22nd April

Pebble Prominent, Westcott 23rd April

White Ermine, Westcott 28th April

They take the garden list well past 100 species for the year, a figure usually achieved during the third or fourth week of April so nothing unusual there.  Last year's poor Spring weather meant that this milestone wasn't reached until 12th May so we really shouldn't complain about the recent run of chilly nights - it could have been far worse!  For the past week I've had anywhere between 10 and 15 species per night with Powdered Quaker and Hebrew Character still in the lead, but they will be starting to tail off now as Treble Lines ramps up in numbers.  Diversity should improve as we get into May.

A species worth highlighting for its better-than-usual numbers this year is Brindled Beauty.  Up until 2018 the average total here was one per season and there were a few years (2005/09/13/15) when it didn't appear at all.  Since then numbers have crept upwards with 16 visiting the trap last year and 20 so far this year, with the last one only three nights ago so that total might still be added to.  Tawny Pinion is also worth a mention after last night's trapping session brought in the third one here so far this year.  I get few sightings of this moth in the garden and it can go several years with none appearing at all.  Those records that I have had are also weighted heavily towards the Autumn rather than post-hibernation in the Spring.

ID help, please

Six of these micros in my trap last night.  I feel I should know what they are but have had to admit defeat so would welcome assistance:

 Photo against 5mm grid square.  No discernible markings but yellow head, some of the others more so than this example.

More early stages

An hour looking around the garden this afternoon in very hazy sunshine produced a few more species.  Yellow-tail caterpillars were out and about, three late-instars on Blackthorn and one early instar on Swedish Whitebeam.

Removing some sprawling White Dead-nettles from on top of our patch of Calamint produced obvious feeding signs on the hidden leaves and a quick check on the underside of a couple of stems produced three active cases of Coleophora albitarsella (a species classified as local).  I haven't previously noticed its early stages in the garden but examples of the adult from here have been dissected almost annually for at least the last 15 years so it is obviously resident.  That find prompted me to look at the copious amounts of Ground Ivy in the garden (another food-plant used by albitarsella) and, sure enough, a handful of additional cases were found on it.

Coleophora albitarsella just visible) on Calamint,

Best find of the afternoon, though, was some unexpected activity on our youngest Silver Birch (one of four in the garden, the other three being mature and their leaves unreachable without a ladder!).  This particular sapling, only about 8ft tall, had been in a pot for several years and was only planted out last summer.  I was very pleased to find some very early Eriocrania leaf-mining under way on at least half a dozen of its very small leaves.  Five of the mines could easily be identified as Eriocrania sangii because of the obvious dark grey larvae within, while the other was a different species and I suspect Eriocrania semipurpurella although it'll have to wait until it is larger to be sure because I don't want to damage the leaves.  Neither species has been recorded in the garden before.

Can anyone identify the aphid?!

Another dumb question??

 Hi there,

I think this might be Tineola bisselliella??

Thanks!

Macro assistance needed with micros!!

 Hi, Being very new to micros, I hope you won't mind if I ask for quite a lot of help this summer - starting with this. Really not sure about it at all. Both photos are of the same specimen.

Thanks, David

Another under-recorded Coleophorid

Robin Knill-Jones has been finding active mines of Coleophora solitariella recently on Greater Stitchwort Rabelera (was Stellaria) holostea adjacent to Great Halings Wood near Denham Green in the far south-east of Bucks.  Classified as Nationally Scarce, this is a species I've never seen.  The literature suggests that the adult rarely comes to light and I'd have to agree with that.  Of only three Bucks records of adults, two were from the Burnham Beeches RIS trap and the third was from a malaise trap on Stoke Common.

I had to go into Bernwood Forest this afternoon so decided to have a look at some of the Greater Stitchwort there myself.  Luckily it is just coming into flower, making it reasonably obvious where to search, but I didn't really expect to find anything.  However, a close look at the lower leaves of some sixty or seventy plants produced three which had appropriate feeding signs although only one had an active case present.  Still, one was enough!  Caution is needed in separating this species from Coleophora lithargyrinella (also Nationally Scarce, not yet found in Bucks although it is known from Berks & Oxon).  It feeds in a similar way to solitariella at the same time of year but there are subtle differences in case construction.

The plant is host to a third species too, Coleophora lutarea, but the larvae of that one feed on the seeds and only form a case when ready for pupation.  As an adult it is a daytime flyer and can be found next month sitting on the flowers of the food-plant.

Phtheochroa rugosana

Only 10 moths to the garden trap last night, but the highlight was this beautiful Phtheochroa rugosana. This is only the second record for my garden, the previous one being in 2018.

Possible Pammene suspectana

 Despite the strong breeze this one came to the FUN lure this afternoon. I think it is likely to be Pammene suspectana although I know it will need dissecting for confirmation.

Daytime garden activity

Yesterday afternoon I noticed the first small larval web of Yponomeuta cagnagella on our garden spindle, some of the tiny caterpillars being just about visible in the photo below.

Yponomeuta cagnagella larval web, Westcott 21st April

Further adult examples of the hawthorn-feeder Incurvaria masculella were also active, two of them being males which were rather oddly paying particular attention to the lowest branches of our hazel - but then I noticed the female sitting on one of its leaves.  Sadly we don't seem to get Incurvaria pectinea around here (whose larvae do feed on hazel).  Back to hawthorn and a quick glance over one of our bushes produced an example of the very smart purple and red tortrix Pammene rhediella in typical pose, sitting on a developing flower bud enjoying the sunshine. It was quickly potted for the image below.

Pammene rhediella, Westcott 21st April

Pammene rhediella is a common species although undoubtedly under-recorded.  There have been relatively few reported sightings in Bucks, probably because it is mostly active during the daytime.  This was the first confirmed record for the garden since 2010 but I suspect it will have been around unnoticed throughout the intervening period.

     I didn't hold out much hope for recording anything today due to the cloud cover and high winds, but the sun unexpectedly broke through briefly this afternoon and a quick look around when it did produced further activity from Incurvaria masculella and my first sighting here this year of Adela reaumurella.

Photographing Emperors to lure

 I seem to remember an earlier post about Emperor moths and lures and them not settling for photos but can't seem to find it now!? That has also been my experience with the lures, although unmated females seem to be more alluring. This afternoon I put out the lure about 6ft off the ground, and the first arrival flew around a bit and then left without landing as per usual . When the second appeared a while later my wife (Cathy ) suggested putting the lure on the ground, since that is where the females usually sit!

Lo and behold the moth proceeded to investigate the trap more avidly and actually entered it allowing some nice photos (after a little bit of refridgerating). (In future this shall be known as Cathy's Technique -all Pats ending US rights Reserved).

A dark Brindled Beauty

I have been seeing a lot of Brindled Beauties in my MV trap in Wheatley, but the attached photo (apologies for poor quality) of a dark form seen last night is the only one of this form I have come across.  Is this common ?  The most common moth seen last night was the Frosted Green - 10 in all (see second photo).

Daytime micros

Two micro-moths from a daytime visit by myself and Sue Taylor to Rammamere Heath (Bucks) last Sunday. Firstly, the tortrix Epinotia tetraquetrana (Square-barred Bell), which is supposed to be a common species that feeds on birch and alder, However, this is only the second time I've seen it, and the first was in 1995!

And here is one of the absolutely gorgeous species in family Eriocraniidae, and probably another birch-feeder, but one that will need dissection to get to a species name. 

First half decent evening in Longwick!

A slightly better selection of moths on the 17th here with a couple of Dotted Chestnuts and a Mullein to add a bit more interest. Esperia Sulphurella also made an appearance. Additionally what appears to be a small Eriocraniidae. is this likely to be Dyseriocrania subpupurella? I cant recall trapping many of this family previously. 

 

Away trapping

While I haven't stopped going to either Finemere Wood or Bernwood Forest, both of which I trap at regularly throughout the year, the last week has seen first visits for this season to three of the half dozen other sites I plan to trap at monthly during 2022.  The first was what Google Earth suggested would be a promising piece of mature woodland in an under-recorded tetrad on the east side of the Waddesdon Estate, but the mix of trees there proved to be mostly Ash, Beech, Horse Chestnut & Sycamore, not exactly the best combination for moths!  They are all quite old and were probably planted when Baron Ferdinand de Rothschild built Waddesdon Manor in the 1880s.  The understory seems to be mostly Snowberry and Sweet Chestnut, but there is a bit of Hawthorn and Hazel dotted about too so I'll have to wait and see what the site produces.  My visit there on the rather chilly night of 14th April produced just 16 species of which the only one to appear in any numbers was Nut-tree Tussock (41 counted).  Least Black Arches & Dotted Chestnut were nice to see, as were new-for-year Small Phoenix, Common Pug & Scorched Carpet.
 

Small Phoenix, Waddesdon Estate 14th April

The next night saw me make a visit to some private mixed woodland near Lillingstone Dayrell on the edge of Silverstone race-course.  This site has a much better potential for moths thanks to it being long-established mixed woodland with plenty of Oak and Poplar as well as various Conifer species.  I made a couple of visits there towards the end of the season last year and it proved its worth then, including the discovery of a healthy population of Devon Carpet (only the fifth known site for that species in Bucks).  On 15th April, another chilly night, I got nearly 30 species of the expected mix for this time of year although few of them appeared in any numbers, Purple Thorn being the clear winner with 14 of them between the two traps.  However, that total pales into insignificance against a count of 51 between two lights in Bernwood Forest a week earlier - Purple Thorn is certainly having a good season locally!

Some of the Purple Thorns, nr Silverstone 15th April

The third site to be visited was one of my favourite trapping locations in Bucks, the chalk downland at Grangelands not far from Chequers in the Chilterns.  Martin Harvey joined me there and between us we ran four lights, my two on the grassland and Martin's in the adjacent woodland.  You don't expect much on chalk grassland at this time of year anyway, but there was an annoying down-slope breeze and then eventually that huge moon appeared over the hill-side behind us, so it wasn't exactly the most productive of nights!  However, our combined species count still reached the mid-20s with Mottled Pug and Iron Prominent both newcomers to me for the year, although the best moth was this fresh (and rather early) example of Ancylis unculana.

Ancylis unculana, Grangelands 16th April

Last night (18th April) I made yet another visit to Bernwood Forest, my fourth there over the past three or four weeks in search of Scarce Prominent.  Thankfully, this time the moth turned up (in fact 13 of them did) although only to the trap closest to the largest area of Birch that I'm aware of there, suggesting that they don't stray all that far from the larval food-plant.  Some very welcome cloud cover and no breeze meant that nearly 40 species were caught in the usual three hours, including Pebble Hook-tip, Birch Mocha & an early Orange Footman.  Great Prominent seems to be at its peak now in Bernwood because 83 of them came to one of the lights for a total of 101 altogether.

Another black & white micro - Elachista apicipunctella?

 Prompted by the post below - I got something very similar a couple of days back. It's going for dissection.
