tricky

Not sure we're going to be able to confirm this from the photo - L. flavicornis would seem to be a more likely solution but without seeing the hindwing (which should have a dark streak towards its tip for Grammotaulius) it's going to be difficult.

Hi Inopinatus and

Hi Inopinatus and Martin,

Yeah L. flavicornis might be the more likely candidate based on its having been recorded in Ireland before. I felt the narrow profile and pointed wing shape of the caddis was more like that of a Grammotaulius. However I do now see how this could well be L. flavicornis. I find I am fairly open minded about what might be there in the west of Ireland now since recording one macro moth on a trip to the same area last July. It turned out to be the very first record ever of the species in that county- there were lots of them. I believe a lot of things are under-recorded in this part of Ireland.

Cheers for the feedback, if I'm back there at the same time this year I'll hopefully get a specimen.

Hi Inopinatus,Ive had a few

Hi Inopinatus,

Ive had a few looks at this caddis above and the species I had originally suggested in the book. Would it be fair to say that the wings are possibly not pointed enough for Grammotaulius?

They are somewhat pointed but maybe that is accentuated a bit by the viewing angle, ie from above as opposed to a proper side on view. It possibly gives the insect a more slender appearance leading me originally to think it had a profile more like Grammotaulius? It does seem to possess the 'greasy' look described in the book for L. flavicornis.

That's possible - I would

That's possible - I would expect Grammotaulius to be more pointed and this does have that greasy look to it. I think what's even more telling is that there's no visible dark streak on the hindwing, as Martin says. In all Grammotaulius that I have seen, this has been clearly visible through the translucent forewing.

Thanks. I hope to photograph

Thanks. I hope to photograph this insect again during the course of the year. A good shot of the individual insect is the main objective. Most probably flavicornis as you say.

Hi Inopinatus, Looking

Hi Inopinatus,

Looking through pics from last summer I happened to find this image here, which is just what I was hoping to get in the summer ahead, I think?
