Poison Ivy Sawfly - Arge humeralis

Poison Ivy Sawfly - Arge humeralis
Groton, Middlesex County, Massachusetts, USA
August 18, 2013
About a dozen of these sawfly larvae were feeding on a poison sumac in my yard. I didn't know what the plant was until after I identified the larva on bugguide and looked up its foodplant. Next thing I did was start washing my hands:-)
