I have groups of these guys in my potato plants this summer. Not sure what they are, if they sting, if they bite or if they are eating my plants. Please help if you can.

Dear DAMMhstead,
We believe we have correctly identified this Sawfly as
Trichiosoma triangulum thanks to this BugGuide image.  According to BugGuide:  “Larvae feed on leaves of alders (Alnus), ash (Fraxinus), poplars (Populus), willows (Salix), cherries (Prunus)”  so we can’t explain why they are interested in your potato plants.  Sawflies do NOT sting, but they are classified in the insect order Hymenoptera that includes wasps and bees.
