This insect landed on a volunteers arm while she was working away on our small farm in northern Aisen, Patagonia. We have never seen it before and wonder what it is? In adavance thanks for the work that you do, it has enabled us to better understand our ecosystem.

Stonefly

Dear Paul,
This is a Stonefly in the order Plecoptera, a species generally found near water as the larvae are aquatic nymphs.  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.”
