Do velvet ants live in colonies?

Velvet ants are not ants, but wasps in the family Mutillidae. Only the females look much like ants; the males have wings like any other wasp. The only antlike thing about them, apart from the fact that they are both in the order Hymenoptera, is that the wingless females look like ants (large, and often spectacularly coloured), and that they can sting very painfully. They do not collect food, but seek out prey, near which they deposit their eggs or larvae. They therefore have no real reason to live in colonies and are not adapted to do so. In fact, given that they have to seek out individual prey, which can be very difficult to do, it definitely pays them to stay away from each other so that they do not compete in finding prey.
