This is a "Velvet Ant" or "Cow Killer" found running across the yard today. I have seen photos of them before but this is the first live one I have seen. Some internet facts:
Common Name: Red velvet ant or "cow killer"
Scientific Name: Dasymutilla occidentalis (Linnaeus)
Order: Hymenoptera
Description: These insects are wasps, not ants. Females are wingless and covered with dense hair, superficially resembling ants. The red velvet-ant is the largest velvet-ant species, reaching about 3/4 inch in length. They are black overall with patches of dense orange-red hair on the thorax and abdomen. Males are similar but have wings and can not sting.
Life Cycle: Females seek the immature stages of ground-nesting bees, digging to the nesting chambers and eating a hole through the cocoon. She deposits and egg on the host larva, which soon hatches into a white legless grub. The immature velvet-ant eats the host larva, developing through several larval stages before forming a pupa.
Habitat, Food Source(s), Damage: Mouthparts are for chewing. Lone females can be found crawling on the ground, particularly in open sandy areas. Adults are most common during the warm summer months. Larvae are solitary, external parasites of developing bumble bees.
Pest Status: The common name, "cow killer," is thought to describe the painful sting these insects can inflict to man and animals, although it is doubtful that many cows are actually stung.
