Blister Beetle: genus Megetra

Hi Willis,
This is a Blister Beetle in the genus Megetra.  You can see more images and get information on BugGuide.
We love your photo with its alarming color palette.  The Blister Beetle does have warning colors for a good reason.  It can exude a blistering agent called cantharidin.
