New micro species for Vice County 35

Carpatolechia fugitivella- Brand new micro for Vice County 35. 

Carpatolechia fugitivella (Elm Groundling)

20th June
Traphill Wood, Mounton

After watching the weather radar for some time this early evening I decided I would get a quick trapping session in, at a local wood. Rain was expected to arrive just before 1am BST on the 21st for a couple of days now and this evening there was no change in the forecast whatsoever- it was far out to west of Chepstow and would definitely arrive close to the time predicted.
This would give me maybe a 2 an a half  hour slot to gain some information on Lepidoptera at Traphill Wood.
A quick setup and switch-on initially didn't spark too much interest. Interest in the light appeared slow and was not too forthcoming on the moth front but did pick up slowly to give a final total of 47 moths of 28 species before I had to frenetically pack-up the trap as heavy raindrops started to fall at around 12.40am.
A couple of localised macro's appeared before the rain with a Treble Brown Spot and a very nice Round-winged Muslin of which I've only seen twice before. It's the first I've seen in a woodland habitat though.

Eudonia delunella and Nemapogon clemeatella were the best of the micro's with another obscurely marked micro in the pot pending photographs for an ID.

This micro I photographed and sent off to Sam Bosanquet and hoped it might come to something.
I actually thought it had water damage at the base end towards the termen which had deflected away the possibility of  ID but did find it odd when the two I potted up were identically marked in the same place and they were captured before any rain fell.
Sam put forward a possibility, but wanted another expert opinion in the form of Stephen Palmer to look over this obscurely marked micro for a positive identification.
The final result was positive for an identification with an Carpatolechia fugitivella (Elm Groundling). This immediately made this a new find for me but most importantly added a new micro moth to the Vice County 35 List.


The micro apparently relies on Elm and Wych Elm for it's foodplant which is fairly common I think in the county. Flight season is in June and July mainly for the adult but can be seen in August.
The raised scale tufts is reliable indicator for this species. 

My thanks to Sam Bosanquet and Stephen Palmer for their work in getting this micro identified.
