velico ergo sum
looks more like Coleophora hemerobiella but i think either would be good for Glos so best confirm by dissection.

Thanks for that
I seen what you mean about Coleophora hemerobiella.
It's always the small ones that seem to be more interesting.

Interestingly, point 1 of the key to adult coleophora in MOGBI Vol. 3 page 146 states:-
'Forewing appearing grey with a greyish fuscous stigma at end of discal cell - C. hemerobiella
Forewing either without a stigma or ferruginous-brown - go to 2'
https://www.amentsoc.org/insects/glossary/terms/discal-cell
Its been a job for every winter for the last four to read the Coleophora keys at leisure! Still not done it.
Does this imply adspersella does not have the stigma?
All the best

According to Gaunt 2000 and subsequent MM records
Coleophora hemerobiella known from Tewkesbury 1985 (cases on Pyrus), Chase End 1999 & Pool Hill 2001
Coleophora adspersella is Nb known only known from from single Pool Hill record in 1998.
So well worth sending specimen to county recorder.

Hi
There's a good reason that C. hemerobiella is at the start of the key - it is the easiest (and one of very few) species to be able to identify by eye. It is the only one with this dark forewing spot. So yours is C. hemerobiella. C. adspesella is a very different looking beast - much more of a streaky coleophorid, and best identified by dissection - or breeding out from the case.
