Quite often I see the somewhat ominous looking “Cow Killer” ant. The name inspires dread and indeed these insects look like they could pack a serious sting. In actuality they are not an ant but rather a type of wingless wasp. And yes, they do have a nasty sting, but I question whether they have ever killed so much as a rabbit.
Sometimes these insects are called Velvet Ants for the velvet texture of the red on their exoskeleton. These wasp can be found scurrying along the ground at a frenetic pace and quite oblivious to your presence.
Picking up or trying to handle these insects may give you a reminder that wasps can sting.
