velvet ants or cow killers despite their name are not ants and actually are a family of wasps. They probably get the name ant due to their lack of wings (males have wings but look completely different) and appearance (even though ants and wasps are related), they get the name velvet from their dense and bright colored hair. They are also known for their extremely painful stings which is where the name cow killer comes from. although they usually feed on nectar after a female mates with a male she will infiltrate another insect nest and lay here eggs there, the young will develop as ectoparasites and kill their hosts after a matter of time. Velvet ants can be found worldwide but are most common in North America and parts of Central america.
