Cow Killer!

Several people have reported seeing these wonderful insects over the last couple of days. These are sometimes called velvet ants. They are not ants but mutillid wasps. The females are wingless and usually brightly colored-orange or orange and black, though a few are grey. The males are winged. The females are enter the burrows of ground nesting bees and wasps and lay their eggs on or near the larvae of their host. The eggs hatch and the Mutlillid larvae feed on the host's larvae.

Mutillids can pack a powerful sting-especially the one pictured here. That probably is the origin of the other common name as a figure of speech- "Cow Killer." The females are extremely active and never seem to stop moving so it is difficult to get a decent picture of them. Fortunately I had a plastic lid to a lens filter handy and was able to trap this one long enough to get a good shot.
