As the name implies, these little insects live twisted lives. The females embed themselves inside other insects, like bees or wasps, with only the “anterior region” (her butt, basically) sticking out. A male parasite then comes along, inseminates her, and flies away. He dies soon after, having lived just a few hours post-hatching. Then the female hatches her brood and her babies eat her from the inside out. Ah, motherhood.
