My daughter is thrilled to find these "shiny beetles" every summer on some plants we have in our field. They seem to prefer the milky plants and flock there for the summer months. If you could identify it for us it would be great. We live in central Maine. Thanks for your help.

Hi Tamara,
This is the Dogbane Leaf Beetle, Chrysochus auratus. It feeds on dogbane and members of the milkweed family. They are very metallic in shades of blue, green, copper and brass. When disturbed the beetles will drop to the ground to hide and when caught will exude a foul-smelling secretion.
