Hi Ahb,I think it can only

Hi Ahb,

I think it can only be lunatus, its sometimes stated that the lunar crescent should typically be edged in a black line but I think this is slightly variable. I see quite a few just like this among 'typical' lunatus.

Im referring mainly to The Adult Trichoptera of Britain and Ireland by Barnard and Ross 2012 fo caddis fly identification.

Caddis Fly ID!

Thanks Cathal

Have to admit not initially knowing what this fly was at all - not sure I have ever really known before what a Caddis Fly looked like!

So I was not expecting a species-level ID at all.

Good to have learnt a bit more - encourages one to look harder next time.

Cheers

Hi Alan, Thankfully lunatus

Hi Alan,

Thankfully lunatus has this distinctive pale crescent (I hope others confirm this ID) which makes it easier to ID than most Limnephilus caddis. There are quite a few in the genus (20ish). I will check the book.

Cathal.
