Drunella coloradensis (Small Western Green Drake) Mayfly Nymph Pictures

Drunella flavilinea

This group of nymphs doesn't include the other one photographed here, but I included it to illustrate the variety of colors found in this species in the same river.

Note this nymph is a lot larger than the size 18 hook in the picture, at least a 16 or perhaps 14. It was just squirming around too much to photograph next to the correct hook size.
