Figeater Beetles!

Lately I've been noticing a beautiful iridescent green beetle that looks too heavy to fly, yet it flits around the yard making noise like a bumble bee. They are so pretty that I have been leaving them alone, but today I realized that they are Figeater Beetles (Cotinis mutabilis). They apparently eat fruit. I have seen countless of their large fat grubs when I've been digging in the mulch, but I never made the connection until reading more today.
