epizoic

Like most other epizoic species, there is no fossil record, but they are probably no older than late Tertiary.

The epizoic species, sometimes considered as ectoparasites, are wingless.

Species of the suborders Arixeniina and Hemimerina are generally considered epizoic, or living on the outside of other animals, mainly mammals.

Many are epiphytic (grow on other algae or marine angiosperms), or epizoic (grow on animals), and some are even parasitic on other corallines.

On the carapace of Kiwa n. sp., a "halo" of pale colouration surrounding the limpets indicates where this species of Lepetodrilus is grazing epizoic microbes.

The first epizoic species of earwig was discovered by a London taxidermist on the body of a Malaysian hairless bulldog bat in 1909, then described by Karl Jordan.
