Hi Daniel~
I found this critter on ME last night, and I kept him overnight for observation and identification until I could get a good photo of him in the daylight. I do believe (from his eyes!) he is a green immigrant leaf weevil, a relative newcomer to these parts, Polydrusus sericeus.
All the best to you!

Green Immigrant Leaf Weevil

Hi Dori,
We concur with your identification of this Green Immigrant Leaf Weevil,
Polydrusus sericeus.  According to BugGuide, it is:  “completely covered with metallic green scales except for brownish or yellowish-brown legs and conspicuous black linear grooves in elytra; eyes relatively large, positioned dorsolaterally, and angled slightly inward (i.e. anterior margin or eye is closer to the midline than posterior margin); least interocular distance less than or equal to width of eye; elytra almost parallel-sided, widest near the base; anterior margin of snout straight, with no notch in middle” and it feeds on “primarily Yellow Birch (Betula alleghaniensis).”  It was:  “introduced from Europe, where it is widespread.”
