A daytime visit there on 19th April to carry out a butterfly transect also produced my first 2017 sightings of Micropterix calthella, with half a dozen seen on dandelion flowers (including the mated pair below).  A single fresh female Endothenia gentianaeana was also found flying around teasels.

I have done my best on the two images. Hopefully  the images are good enough.
Depressaria radiella and Epinotia immundana. Hopefully near?

Night of Prominents

With permission from the site management, Martin Albertini, Andy King and I ran traps on Stoke Common, Bucks last night and we ended up with just over 40 species after the usual three hours.  The Prominents were out in force, with Iron, Pebble, Lesser Swallow, Coxcomb, Pale and Great all recorded.  Close relatives Lunar Marbled Brown and Chocolate-tip were also seen but unfortunately there was no sign of Small Chocolate-tip which was our target for the night.  This is a moth which hasn't been recorded at Stoke Common since 2011.  Its main food-plant is the very low-growing Salix repens (Creeping Willow), a "tree" I hadn't really noticed before - not surprising really as we saw none of it taller than a couple of feet above ground level!  However, with the catkins currently present to make it obvious, it does seem to be quite widespread on Stoke Common even though decidedly uncommon in the county, so there's hope yet for the moth.

Most numerous species of the night was Narrow-winged Pug with more than 100 coming to the lights (64 to mine alone), while other species in the traps included a female Emperor Moth, Scalloped Hook-tip, Oak Hook-tip, Pebble Hook-tip, Birch Mocha, Maiden's Blush, Peacock Moth, Tawny-barred Angle, Grey Birch, Lime Hawk-moth and Shuttle-shaped Dart, many of which were on the wing rather earlier than normal.  Half a dozen micro species were recorded, of which Neofaculta ericetella was the only one to reach a double-digit count.  Others included Ancylis uncella, Epinotia immundana and, off the abundant gorse, the inevitable Cydia ulicetana.

May I ask for help with this little visitor?  He or she looks familiar, but as usual, I cannot nail the name.  I will guess a battered Mompha subbistrigella, just on the grounds that I should at least try. Help much appreciated.  Martin Wainwright, Thrupp, Oxon

Pugs yet again

I got three last night. One was a V Pug - the other two I don't know even after reading Dave's descriptions. Saw a couple of Brimstone moths last night but as often, none in the trap this morning. Got a Waved Umber which was nice and a Streamer which was NFM.

Pugs again

Apologies for asking about pugs again. I had 4 pugs in last night's catch. I could manage to identify one of them confidently as a V pug. These were the other 3.

The first 2 maybe Brindled or Oak-tree? I am finding it difficult to separate the two.
The third maybe Double-striped? If so much more colourful than those caught previously this year.

Pseudococcyx turionella

I collected some Scots Pine shoots the other day from Stoke Common, Bucks and one moth has already emerged from a bud:

This is a Pseudococcyx turionella. The larvae have a tendency to live in (and destroy) the terminal bud during the autumn, winter and spring. Not, I imagine, popular with Forestry Commission people, but the moths are reasonably scarce.

Westcott, Bucks

I happened to notice what I think is a part-grown (9mm) Sloe Pug caterpillar here this afternoon, quite an achievement considering how well camouflaged it was in amongst the blackthorn blossom.  I get the moths regularly in the trap so it would be no great surprise to find that it breeds in the garden. See comments below.

Possible Sloe Pug larva, Westcott 18th April

The actinic trap has continued to pull in at least one new species for the year-list each time it is run, with Brindled Beauty & Bright-line Brown-eye (both 14th), Epiphyas postvittana (15th), Endrosis sarcitrella & Pebble Prominent (both 16th) and Frosted Green (17th) being added over the last few nights.  Neither Frosted Green nor Brindled Beauty appear here every year so they were particularly welcome visitors.  Chocolate-tip continues to visit the trap most nights and seems to be doing really well locally.

Nice selection.

Very few moths at the moment up here on the hill but the few that do turn up are very nice.
Yesterday Chocolate-tip and Pebble Hook-tip and this morning this Dotted Chestnut (FFG)

Powdered Quaker?

Caught this a while back - books seem to be a bit vague on diagnostics between this variable moth and the variable Common Quaker - I'm tending to Common Quaker on the basis of the wing shape but i thought I'd check.

Emperor assembling question

Hello again.  Following my last post, on assembling male Emperor moths, I have been pondering the way that my three, after finding their way to the captive female from possibly long distances, made a mess of their final approach and ended up fluttering about in our shed while their target was perched unconcerned on the outside wall.

My theory, after reading about the males making sometimes erratic circles as they get near to the female (rather than heading straight towards her) is that one of these manoeuvres took them through the open door of the shed (a couple of inches to the right of her perch) and thus into what turned out to be a trap, working on the same lines as a lobster pot or indeed Robinson moth trap, in that the door and windows acted like funnels, easier to enter by rather than exit through.

Does this make sense?  I also got the feeling that a captive female simply left in the open (where she showed no desire to escape or fly away) was much more effective than confinement in a muslin bag. Does others' experience also suggest that?

At all events, a highly enjoyable and interesting exercise.

Garden stuff...

Not a lot in the garden at the moment, but I did get NFY Scorched Carpet in my GMS catch. Also the following pug, which I'm thinking "Oak Tree"?

 Plus, during the day, a trio of Adela reaumurella

Another Oxfordshire White-marked?

Looking through previous posts I think this is a White-marked but would appreciate confirmation as it would be a new species for me. The first image is an attempt to get a close-up of the antennae.

Passionate scenes

After a couple of duff attempts using a muslin bag, I released my female Emperor moth - the finally-hatched 23rd child of the female which visited me in May 2014 - on to the outside of our shed yesterday. There she perched, apparently unvisited, but in the late afternoon, I went to put back garden tools and the inside of the shed was aflutter with three lustful Emperor males.

I out them all together in a box and one eventually established dominance and locked on. All four moths are now at large in or around Thrupp, and I hope that this dynasty, which has provided me with so much interest, continues to flourish. And I still have two cocoons unhatched from the original 25.  Martin Wainwright, Thrupp, Oxon
