Hardy Moths

Not at all surprising because the temperature had dipped below freezing before midnight, but just two very hardy moths came to last night's garden actinic trap here, the Early Grey and Hebrew Character shown below.  With another frost forecast for tonight I might give the trap a rest, which will be the first occasion that's happened since mid-February.

Early Grey & Hebrew Character, Westcott 25th April

While cutting back some honeysuckle yesterday I disturbed a smart female Esperia sulphurella.  The moth is a regular here, presumably thanks to two or three piles of decaying logs left around the garden.

Very early 60th

Last night saw Common Wave and Knot Grass come to the actinic trap here at Westcott, taking the total number of macro-moth species recorded in the garden this year to 60.  Nothing much to shout about there, you might think, but certainly for at least the previous ten years that total has never been achieved so early in the season and only once before in April: 

5th May

22nd May
Mottled Pug
11th May
Clouded-bordered Brindle
30th May
Common Wave
10th May
Green Carpet
9th May
Iron Prominent
20th May
Grass Rivulet
10th May
Orange Footman
28th April
White Ermine
17th May
Knot Grass

While counts will vary from site to site, this has certainly been a very unusual year so far with many species appearing far earlier than is normal.  The average date to achieve 60 macros here is 13th May.

Another Acronicta species was the only thing of interest to an MV trap run for the usual three hours in Bernwood Forest last night where an early Alder Moth put in an appearance (I won't go on about how the Met Office got their forecast of night-time cloud cover completely wrong yet again...).  The very chilly conditions didn't seem to affect either Lesser Swallow Prominent or Great Prominent which were still arriving as I packed up (final counts of 10 and 44 respectively) but there was nothing else of note.

First hawkmoth at Coleshill

Although the temperature dropped quite a bit as the cloud moved off last night, there were 21 moths of 14 different species in the trap this morning including the first Lime Hawkmoth recorded this year, along with Coxcomb Prominent, Chocolate-tip and Frosted Green new for 2017. Also present was this fairly large pug which I'm having trouble placing - the markings being different from the usual Oak-tree and Brindled Pugs seen at this time of year before and the dark stripe along the abdomen was striking. Couldn't get a ruler near it in time for measuring the size before it escaped but it was fairly large at about 20 mm across.

Finemere Wood, Bucks

I ran a trap in Finemere Wood, Bucks last night for three hours and got a reasonable return of the following 31 species:  Dyseriocrania subpurpurella, Parornix sp, Phyllonorycter sp, Syndemis musculana, Chinese Character, Frosted Green, Red Twin-spot Carpet, Streamer, Water Carpet, Brindled Pug, Oak-tree Pug, Seraphim, Clouded Border, Scorched Carpet, Brimstone Moth, Brindled Beauty, Engrailed, Lesser Swallow Prominent, Pebble Prominent, Coxcomb Prominent, Great Prominent, Chocolate-tip, Lunar Marbled Brown, Pale Tussock, Flame Shoulder, Red Chestnut, Blossom Underwing, Common Quaker, Clouded Drab, Hebrew Character & Nut-tree Tussock, of which Seraphim, Clouded Border, Pale Tussock & Flame Shoulder were new sightings for me this year.

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.
