Insect subfamilies

Fishflies are members of the subfamily Chauliodinae, belonging to the megalopteran family Corydalidae. They are most easily distinguished from their closest relatives, dobsonflies, by the jaws (mandibles) and antennae. In contrast to the large jaws (especially in males) of dobsonflies, fishfly mandibles are not particularly noticeable or distinctive, and the males have feathery antennae similar to many large moths. Chauliodes pectinicornis, the "summer fishfly", is a well-known species in North America.

Blattellinae is a subfamily of the wood cockroach family, Ectobiidae (formerly "Blattellidae"). It includes the global household pest Blattella germanica, the German cockroach, and a number of endangered species. It contains about 70 genera.

Atelurinae is a subfamily of primitive insects belonging to the order Zygentoma. Once considered an independent family, it is now treated as a subfamily within the Nicoletiidae. They are generally found in association with ants or termites, living as inquilines in the hosts' nests. They are typically small, tear-drop or sub-ovoid in body shape, light yellow in color and lacking eyes. The subfamily is quite diverse, with more than 140 described species in about 70 genera; many of the genera are monotypic.

The Phlaeothripinae are a subfamily of thrips, with hundreds of genera.
