The antlions are a group of about 2,000 species of insect in the neuropteran family Myrmeleontidae. They are known for the predatory habits of their larvae, which mostly dig pits to trap passing ants or other prey. In North America, the larvae are sometimes referred to as doodlebugs because of the marks they leave in the sand. The adult insects are less well known due to their relatively short lifespans compared to the larvae. Adults, sometimes known as antlion lacewings, mostly fly at dusk or after dark and may be mistakenly identified as dragonflies or damselflies.
Chaoboridae, commonly known as phantom midges or glassworms, is a family of fairly common midges with a cosmopolitan distribution. They are closely related to the Corethrellidae and Chironomidae; the adults are differentiated through peculiarities in wing venation.
Cryptophagidae is a family of beetles with representatives found in all biogeographic realms. Members of this family are commonly called silken fungus beetles and both adults and larvae appear to feed exclusively on fungi although in a wide variety of habitats and situations, such as rotting wood and shed animal fur and feathers. These beetles vary from about 1 to 11 millimeters long, and usually have an oval body shape with a slight "waist".
The Polycentropodidae are a family of trumpet-net and tube-making caddisflies. There are at least 30 genera and 720 described species in Polycentropodidae. The type genus for Polycentropodidae is Polycentropus J. Curtis, 1835.
Heptagenia is a genus of flatheaded mayflies in the family Heptageniidae. There are at least 20 described species in Heptagenia.
Kateretidae is a family of short-winged flower beetles in the suborder Polyphaga. There are about 11 genera and at least 40 described species in Kateretidae. They are found worldwide except in New Zealand. Adults are anthophagous, feeding on flowers, while the larvae are spermatophagous inside the flower corolla.
