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?
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.
