Elm leaf beetle larva and eggs - Xanthogaleruca luteola
Pilot Rock, Umatilla County, Oregon, USA June 30, 2014 Size: 2mm
On my Siberian Elm ... quite a pest. Should be Xanthogaleruca luteola.
I am linking two pictures here, the next one is of an older larva. If they needed to be un-linked I apologize.
