How about a wasp with bottom mimicking an ant's head?

  • Wasps bottom mimicking an ant
This seems a joke but must be a reason for it
 
A fascinating example of mimicry in the natural world is shown by Clistopyga Caramba (named after the Spanish exclamation of surprise), a type of ichneumon wasp with a tail that resembles an ant's head. It is thought to use this to attract spiders they prey on and ward off predators that avoid ants. Let's hope that nobody plays an April Fool on anteaters by giving them these wasps instead!
