- Sucking louse - Phthiraptera
While there is some disagreement on the exact methods for categorizing them, lice like this human louse may be considered to belong to the order Phthiraptera (includes all lice) or separated into Mallophaga (just chewing lice) and Anoplura (just sucking lice). - Flea - Siphonaptera
Fleas currently are believed to be a strange version of scorpionflies, but traditionally are given their own order called Siphonaptera.
