The short version

The velvet ant isn't an ant at all — it's a wingless female wasp whose sting is so ferocious it earned the nickname 'cow killer,' with burning pain lasting over half an hour. Its exoskeleton is armored enough to resist a collector's pin, it squeaks a warning when threatened, and it parasitizes the nests of other bees and wasps.
