Life History. Pardalosus neodistinctus and P. sleveni are collected in association with rodents; prairie dogs and pack rats respectively. The other species may be detritivores, and are not usually collected in association with dung.
Larvae. The larva of P. pardalis is described in Ritcher (1966).
Status of Classification. There are presently 3 recognized species groups, based primarily on external morphology. They are easily distinguished based on genitalic characters and distribution.
