Leptinotarsa decemlineata - Male Female
Kennebunkport, York County, Maine, USA
June 25, 2015
I noticed that the guide didn't have any photos of this genus from Maine yet (!), so I went out to a local spot where I found them several years ago. Sure enough, I saw quite a few individuals feeding on Deadly Nightshade (edit: probably NOT that species, see comments). Interesting how the maculation on the pronotums of these four differs slightly.

I believe these are L. decemlineata - looks like 10 black stripes, no brown stripes, and elytral punctures look irregular. But I wanted to get it confirmed before moving it to the species page.

Deadly nightshade?
Are you sure it was deadly nightshade (Atropa belladonna) and not one of the members of the black nightshade complex, like Solanum nigrum, S. americanum, or S. ptycanthum. Sorry, plant nerd here.

Yeah, it probably was one of the Solanum species. It was growing in sandy, gravelly soil along a beach if that helps.
