Do Head Lice Jump?

In order to "catch lice", a live bug must transfer from one head to another. Human head lice crawl incredibly quickly, and that is the only way they transfer from head to head. Lice do not have legs biologically capable of jumping. If someone shows you a louse "jumping", it is either not a human head louse, or it is actually trying to crawl, and somehow is falling, perhaps because it is dying, or because the louse is trying to crawl up the inside of a jar! Lice may twitch for a few seconds while they are dying, and this can be mistaken for jumping lice. HAIR LICE don't JUMP!
Considering that head lice don't jump, how to they spread so fast?? Amazingly lice crawl very quickly, from one head to another. It really only takes one or two head lice to infest another person. Children spread lice more quickly, because in the course of their play, they give the lice more opportunities to crawl from one head to another. This can happen when sharing a secret, wrestling, and hugging. Any head to head contact gives the louse a chance to transfer. Until you look under a magnifying glass, it's hard to believe how quickly head lice crawl.
