Truthfully, I think it’s officially only one species, a chewing louse that lives exclusively on owls.

Terms dreamed up by Larson – as in his cartoon of a caveman pointing to the tail of a stegosaurus and telling his audience that it is named “the thagomizer, after the late Thag Simmonds”, led paleontologists to adopt the invented word, while Larson himself has a species of chewing louse named after him: Strigiphilus garylarsoni.
