January 5 - Peristenus digoneutis

If you liked the movie Alien, then you might be a fan of parasitic wasps, such as Peristenus digoneutis. These insects, sometimes incredibly tiny, capture and kill other insects (in this case little plant bugs) that they then lay their eggs into. The larvae hatch out and eat their hosts from the inside out. Although it's rather gruesome, these parasitoids have been developed as biocontrol agents to combat insect pests.
