Hi Bugman,
I found about ten of these clinging to the outside of my house at the end of February (unseasonably warm day). Can you help identify?

Dear jkayman,
This is a harmless Stonefly.  They are generally found not far from a stream or river.  Additionally, according to BugGuide:  “nymphs of most spp. develop in cool, well-oxygenated water and do not tolerate pollution; therefore, their presence is an indicator of good water quality, and their absence in areas where they previously occurred may indicate pollution.”

Thank you very much Daniel.  I do indeed live by a river.
Appreciate it.
