Friend sent me these slightly fuzzy pictures to see if I could find someone to identify this creeper.

Pic taken lakeside, in Southern Ontario (north of Toronto), on top of a 41/2" fenceboard, is limegreen, and seems to be a solo hobo. I'm not sure how to get two pics loaded here, but will give it a try. Thanks for your time. Oops..I will try and crosspost over there in Insects..I've just seen the heading, sorry!
