Stonefly Larva - Acroneuria

Stonefly Larva - Acroneuria
Grantham, Pennsylvania, USA
November 6, 2004
This picture was taken fall 2004. The insect was found under a rock in a creek. I believe that it may be a stonefly larva, but does anyone know for sure?

Moved from Common Stoneflies.

Moved from Stoneflies.

Kerry's right
This is surely a perlid. It's an immature specimen, so I won't go beyond the Acroneuria ID.

Stonefly Larva
According to the photos in the National Audubon Society Field Guide, it sure looks like a "common stonefly naiad".

This is definitely a stonefly nymph, naiad, or larva (your choice as to which term to use:-)

IMHO: I'd place it in Perlidae (NOT Perlodidae) most likely Acroneuria sp.
