Here's a doting motherly wasp on my driveway. You'll notice she's got a spider in tow. Earlier she found this spider and stung it just enough to permanently paralyze it. She'll haul it back to her nest, probably made of mud in some inconvenient place on equipment or in my shop, and lay her eggs on this spider. Since the spider is paralyzed, it'll stay fresh until the wasp larva hatch. Then the babies buffet will begin. Good for the wasps, not so good for the spider. Nature's not all bunnies and rainbows is it?
