Dobsonflies are a subfamily of insects, Corydalinae, part of the Megalopteran family Corydalidae. The larvae (commonly called hellgrammites) are aquatic, living in streams, and the adults are often found along streams as well. The nine genera of dobsonflies are distributed in the Americas, Asia, and South Africa.

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.

Corydalus is a genus of large flying insects in the Corydalidae family, commonly known as dobsonflies. They are endemic to North, Central and South America and there are about 35 known species. Members of the genus have wing lengths of up to 85 millimetres. They are sexually dimorphic, with the males having large mandibles used to grasp the females during mating while the females have smaller jaws. The larvae are known as hellgrammites and are aquatic predators.

Protohermes is a genus of dobsonflies in the family Corydalidae. Protohermes is the most speciose and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia. This endemism may be a result of an association with high elevation and high slope streams in Northern Vietnam and China.
