Sweltsa onkos (Sallfly) Stonefly Adult Pictures



 I'm just guessing this is Chloroperlidae, since it's little and yellow. If anyone has a less haphazard identification, feel free to post it.

This stonefly was collected from Mystery Creek #62 on May 15th, 2007 and added to Troutnut.com on May 18th, 2007.

I believe this is probably Sweltsa onkos. There are three Sweltsa species commonly listed for most of the Northeast (onkos, naica, and lateralis), and their individual pronotum/head markings seem rather distinctive.
