they are asian beetles.as carlton mentioned they were introduced here to control bean aphids.they don't show up here til the farmers start taking the beans out of the fields.then look out.don't smash em with your fingers they stink.

I've noticed that in the fall, Carpenter Peak, the conclusion of a nice hiking trail in the foothills outside Denver, is covered with ladybugs.
