 Hi,
I found this larva in a small stream in West Finland.
I took the photo on 16. 12. 2014 Kokkola, Finland.
Size 36mm.

Thanks.

Regards Pentti.

 Perhaps a gyrinid beetle larva?

 Thanks Paul!

I think this could be Gyrinus paykulli?

 Not a beetle, but another Trichoptera - family Phryganeidae, probably Agrypnia

 I agree with Tony, Phryganeidae for sure, genus Agrypnia (not pagetana) or Phryganea. Studying the combs on the middle- and hindcoxa and/or the presence or absence of a small sclerite between the front legs is necessary.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
