I found these beetles on milkweed and have tentatively identified them as Blue Milkweed Beetles. Is that your assessment too? And is that the beetles’ genitalia that I am seeing in the second photograph?

BugGuide refers to Chrysochus cobaltinus as the Cobalt Milkweed Beetle. Your photo of a couple in the process of mating is a nice addition to our Bug Love pages. We will try to get an answer on the genitalia question for you.
