Ticks are small, blood-sucking arachnids of the order Parasitiformes, with over 900 known species. They most likely emerged during the Cretatious (65-145 million years ago), and have thrived in warm, humid climates, ever since. Parasites, ticks survive by drinking the blood of their hosts -- typically mammals or birds, occasionally reptiles or amphibians -- an act that in and of itself is typically not harmful, but one that makes them a serious vector for diseases that affect humans and other animals, such as Lyme disease.
Body horror in the insect kingdom
Learning about animals, you can discover many fascinating, even beautiful facts, but there are also things that can give you nightmares! Enter the strepsiptera (“twisted-wing parasite”). The adult female has no limbs, wings, or mouth - she simply lives in and feeds off her host (typically a wasp). When it becomes time to mate, she protrudes part of her abdomen from between the plates of her host and uses mind control to get the wasp to fly off to nearby males. Sexually mature males have wings, and fly around for about five hours before dying - spending their entire short existence seeking out females to mate with. After the female is impregnated, her own young grow and consume her. And once there is nothing left to eat, they leave their host wasp, infiltrate the nursery, and latch on to a larvae to create their own “zombie wasp” host and continue the grisly cycle!
