Dogbane beetles
Dogbane beetles, Chrysochus auratus. Looks like they're on a dogbane leaf, too.

Thanks
I don't know plants. I thought that was some kind of milkweed (the leaves oozed something milky when I broke one off).

Well...
Milkweeds and dogbanes are in the same family, and both have milky sap. So you were certainly thinking in the right direction.

Close
Milkweed (Asclepidaeae) and dogbane (Apocynaceae) are in families that are very closely related.

Used to be...
Asclepiadaceae and Apocynaceae have been synonymized. Now they're both Apocynaceae. See the Angiosperm Phylogeny Group (http://www.mobot.org/MOBOT/Research/APweb/) for instance. Basically, Apocynaceae turned out to be a paraphyletic basal grade relative to the more derived genera in Asclepiadaceae, so the cladists couldn't stand it and had to lump them.
