Parasites appear frequently in biology-inspired fiction from ancient times onwards, with a flowering in the nineteenth century.[1] These include intentionally disgusting[2] alien monsters in science fiction films, often with analogues in nature. Authors and scriptwriters have, to some extent, exploited parasite biology: lifestyles including parasitoid, behaviour-altering parasite, brood parasite, parasitic castrator, and many forms of vampire are found in books and films.[2][3][4][5] Some fictional parasites, like Count Dracula and Alien's Xenomorphs, have become well known in their own right.
