Newly Discovered Wasp Species Enslaves Spiders
Spiders spend a lot of time crafting their webs in hopes of making a meal out of all manner of winged insect--but a recently discovered species of wasp is found to use the spider's engineering prowess to it's own advantage. Through a not yet understood chemical process, the wasps are able to, quite literally, enslave the unsuspecting spiders to build a nest for their larva, and after all that hard work, become their first meal. Sure, it seems pretty dastardly, but researchers say it's evolution.
