Found crawling on my brothers leg at fort bliss in Texas….
This is a Blister Beetle in the genus Megetra, a group that is “Restricted to Chihuahuan Desert of the USA (TX, NM, and extreme southeastern AZ) and Mexico (where most of this desert region is located)” according to BugGuide. You were wise to handle this Blister Beetle with gloves because the family is capable of exuding hemolymph that contains cantharidin, a chemical compound that can cause blistering of the skin.
