Winter GMS week 4, digging for pupae
Winter GMS
Trap out last night for winter Garden Moth Scheme week 4. T min 4˚C, 2 December moths (1m, 1f).

Digging for pupae
Like Paul I haven't done this for many years - well over 50 in fact! - I used to look at Lime, weeping Willow and Poplar trees in my and my brother's secondary school playing fields. I found Lime, Eyed and Poplar Hawk-moths, Buff-tip, Pebble Prominent and Brindled Beauty, and a moth which (then) I had never seen before - a Clouded Drab! There must have been other species but they have faded from memory.

Digging for pupae
Now that the moth activity has almost ceased I have turned my attention to searching for overwintering pupae. This is the first time I have done this for almost forty years and it was just as exciting as I remembered (doesn't take much to excite me) I went with a friend to to search around the base of some isolated trees at Claverton Down just on the outskirts of Bath.

From past experience I have found that searching around the base of mature isolated trees in a field or parkland tends to give the best results and that by digging very carefully with a small hand-fork or trowel immediately around the trunk and buttress roots of the tree quite a number of different pupae can be found.  As one would expect Oak can often yield the best results but on this occasion were surprised to find that More were found around an old Ash tree than around the couple of Oaks we tried.

Although we only found a total of just eight pupae and a couple of hibernating larvae in a little over an hour it was a most enjoyable pastime on an autumn morning.

Now comes identification which unless the pupae are very distinctive like the Hawk-moth pupae this can be quite difficult to determine. Starting with the likely species associated with the particular tree and then looking at which species overwinter as pupae and the normal pupation site and by considering their size you can start to narrow down what the possibilities are. One of the identifying features of particular pupae are the shape and form of the cremaster (tip of abdomen) However identifying the exact species can be very difficult and there is surprisingly little on the web although I have found the UK Lepidoptera to be one of the best albeit not all pupae are described or shown. (If anyone knows of a better source then please let me know)

One useful thing about collecting pupae is that the pupae can be sexed and this can help to find females of many species that would not readily come to light in the same way as the males do. This is particularly useful for finding species with wingless females such as Dotted Border or Pale Brindled Beauty which you would not normally see.

If you haven't already tried winter searching for pupae then give it a try it's like searching for buried treasure!

Not having seen any December Moths last year I was suprised to get 11 last night! Also 2 Light Brown Apple Moths, 2 Acleris sparsiana, 1 Beaded Chestnut, 1 Yellow line Quaker and 2 Mottled Umbers - not spotted till the daylight was stronger as they were both camaflauged on a piece of rusty iron (very few moths were actually 'in' the trap). One of the Mottled Umbers was less distinctly marked and puzzled me for a while.
Also seen yesterday daytime was a ? Buff Tailed Bumble Bee queen carrying quite a bit of pollen which seemed a bit early or late to be pollen gathering.

Nigel - thanks! I still have not got round to subscribing to Atropos. Also I forgot to say that A logiana seems to have been expected in Somerset for a while as it has spread from the S.E and been seen in Devon already.

East Lydford 27/11/13
A much more productive night, mild & damp with a small amount of moonlight, giving a total of 9 moths altogether - one each Feathered Thorn & Sprawler, and 7 December Moths, including 2 of the larger females.

This the second largest nightly total of December Moths that I have recorded here, the best being 16 in December 2011.  I recall that the majority of those were not actually in the traps, but sitting around on the wall nearby - funny creatures, moths.

We are promised an even milder night tonight, so I'll probably have another go, to see what's out there. There are several seasonal species which haven't appeared here yet, so I live in hope (as always).

Re: Acleris logiana
Congratulations Liz.

You'll have to write it up and get it published. I wrote a short piece on the Summer Fruit Tortrix which appeared in Atropos No. 49. I'm sure Mark Tunmore would be delighted if you did the same. Contact details can be found at: http://www.atropos.info/site/index.php/contact-us

Acleris logiana
This moth came to my actinic trap at the end of October. It looked so much like the illustration of A.logiana in the micro Moth book - rather than the very similar A.kochiella which I haven't seen - that I contacted Bill Urwin who advised it was worth sending off for confirmation. Phil Sterling kindly agreed to do it (and thought from the photo it 99% likely) and has now confirmed it and it is new for Somerset. He mentioned that until recent years A.logiana was confined to Scotland, and suspects that the ones increasingly being seen in Southern England (where they are double brooded) may have colonised from the continent, maybe Eastern Europe. Its larval foodplant is Silver Birch and the trap was close to S.Birch. I'm finding the world of micro moths quite gripping! Acleris logiana 31.10.2013

Just one solitary Red-line Quaker this morning.  Looking back, I see that these are nearly three times as common (in terms of records) as their cousins the Yellow-line, which I haven't seen here for two years.  Seeing the larval food plants of both species are equally common around here, this is a bit odd, I think.

Leaf miners 'Fill the void'
Thank you James I didn't notice these, well spotted!

Hi John, I have also found good numbers of P. platani on London Plane leaves here in Bath.

At this quiet time of year for moths I'm finding that searching for leaf miners helps fill the void.

The cut-outs on this Hazel leaf are the work of 129 Incurvaria pectinea larvae; I think that this species is also more common than the amount of dots on the map suggests. Found in ST2919 during a 13 mile walk around the Staple Fitzpaine Herepath Trail on 4th Nov.

Recorded and collected about a dozen or so species including a new record for the site 331 Phyllonorycter lantanella on Wayfaring Tree (Viburnam lantana), also found a number of larvae of 1097 Endothenia gentianaeana in the seed heads of Teasel.

Red-green Carpet is correct. Autumn Green Carpet is a duller green colour, with whiter areas, has a more triangular shape and a different hindwing colour. I think this is a frequently misidentified species as there are Red-green Carpet, like yours, with no red. As a newcomer to moths I've never seen it in Somerset, only in Scotland (there's a nice photo on Keith Tailby's website of one we found at Newtonmore services www.mothshots.com/Pages/ImagePages/MacroMoths/Macro-A/AutumnGreenCarpet.htm). In the absence of any evidence I think it was lost from Somerset quite a long time ago.

Norton Sub Hamdon
Promising weather last night produced a healthy November catch of 36 Macros from 15 species. They included some late individuals like Sallow, Snout and Setacious Hebrew Character as well as 3 very fresh Common Marbled Carpets alongside 4 much more worn individuals. Migrants were represented by 4 Dark Sword Grass as well as at least 2 Udea Ferrugalis ( one of the few micros I recognise ).
I was hoping to record Sprawler or Figure of Eight but was unsuccessful.  I have only had 2 Sprawlers and 1 Figure of Eight in the 12 years I have been recording in my garden despite what would appear to be perfect conditions for them nearby.
I also had a very pretty micro that looked like a tiny Merveille de Jour. I have a recollection of someone, probably John, putting a picture of this species on the blog some time ago but I cannot find it. I know I should have a copy of the macro book but I haven't and wonder if anyone can Id it from my description.

A much milder night, with a new moon, should have produced a goodly number of moths, but in the event only 9 found this morning, of 5 species - 3 each Feathered Thorn & Sprawler (FFY), and 1 each Blair's Shoulder-knot, December Moth and Eudonia angustea.

There was also what I think is a Wood Wasp, (but I'm not very well up on these beasties) which is black, about half an inch in length,with a white spot on both the thorax and tip of the abdomen - also the antennae have a pale section in the centre.  Has anybody got any ideas ?  I don't recall ever seeing one like this before, so I'm curious as to its identity if anyone out there knows.  Sorry, I don't do photos !!

I have not contributed to this page for a while as I am overwhelmed by the number of moths recorded by those of you further south in the county, not to say jealous, but as I don't see anyone reporting a Sprawler, I thought I would do so. I haven't run the trap for a few weeks, but get moths attracted to an outside light, which lately have been Feathered Thorns (2), November Moths (2) and last night this Sprawler which is a first for me here (should that be FFMH ?)Sprawler
