Dogbane Beetle

Unknown beetle
Dear Sir,
My mom says this is a Japanese beetle, which would be a bad thing. The Japanese Beetles I have seen on the internet seem to have brown wings, and mine was more green all over, but with iridescent wings. Can you tell me what this is? Thank you! Sincerely,
Melora Campbell

Hi Melora,
You are correct. This is not a Japanese Beetle. It is a Dogbane Beetle, Chrysochus auratus. Unlike the Japanese Beetle which will eat leaves and blossoms from countless 1000s of plants, the Dogbane Beetle feeds exclusively on the leaves of plants in the Dogbane family Apocynaceae.
