Velvet ants

There are over 3000 different species of velvet ants.
The velvet ants aren't actual ants, they are wasps. The males have wings but no sting and the females have a sting but no wings. The males and females are so different from each other, not only in size but also appearance, that it is sometimes hard to tell that they are from the same species.
Some species of velvet ant can kill a cow with their sting, this is why velvet ants are sometimes called 'cow killers' now that is pretty scary!
