Nature can be full of drama.

For example:

full-praying-mantis-and-paper-waspWe've had a Mediterranean mantis,  Iris oratoria, on the rush milkweeds for a few weeks. Today it caught a paper wasp, Polistes flavus.

mantis-flyIt might seem like the fly was incidental, but it isn't. Small black flies of the family Milichiidae are known to steal food from predatory insects and spiders. It is a behavior known as kleptoparasitism.

Being a freeloader that steals food from a predatory insect seems like it might be a dangerous lifestyle, but the mantis seems occupied with the wasp and is not reacting to the fly.
