It's always exciting to see what you can find among the Coleophora, but if you get anything good you tend not to know it until you have it under a microscope. Often though you can have a pretty good stab at the ID beforehand and when you get stuck on externals there's a better chance that the internals will reveal something interesting. That was the case with one of the Coleophora on 4th July. Not obvious what it might be on externals so I chopped it. I didn't immediately recognise the genitalia so at this point I went back to the moth and took it through the key in MOGBI. That often fails - a moth only has to have antennae ringed to the tip when MOGBI thinks it shouldn't and the right answer gets ruled out, for example, but on this occasion it came up trumps. Once a provisional answer had been arrived at I checked the genitalia against that and yes, that was the boy! Ochreous Case-bearer Coleophora solitariella. Not many records in Norfolk and looking at the detail it seems that all the modern ones are of larvae. There are two records from 1874 that don't say if they're adult or not, but mine seems to be the first adult to be found (and identified) in Norfolk in modern times.
That might suggest that they're rather rare, but I suspect they're not really. Stewart Wright has found their larvae in several places over the last couple of years so they can't be all that rare. Various references say the adults are rarely observed, so presumably it just doesn't come to light all that often for some reason. Plus of course it's a Coleophora - not many people bother with them!
