Chauliodinae. Male fishfly (Chauliodinae ssp). Fishflies are members of the subfamily Chauliodinae, belonging to the megalopteran family Corydalidae. [1] 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 ...
Ephemera danica can reach an imago size of 15–20 mm (0.6–0.8 in) in males, while females are larger, reaching 16–25 mm (0.6–1.0 in). This mayfly, with its characteristic markings and three tails ( Cerci ), is the most commonly seen of British Ephemeridae. Imago wings are translucent with dark veining, while in subimago they are dull and ...
Ephemerellidae are known as the spiny crawler mayflies. They are a family of the order Ephemeroptera. There are eight genera consisting of a total 90 species (Merritt & Cummins). They are distributed throughout North America as well as the UK. Their habitat is lotic-erosional, they are found in all sizes of flowing streams on different types of ...
Binomial name. Hexagenia limbata. ( Serville, 1829) [1] Hexagenia limbata, the giant mayfly, is a species of mayfly in the family Ephemeridae. It is native to North America where it is distributed widely near lakes and slow-moving rivers. [2] The larvae, known as nymphs, are aquatic and burrow in mud and the adult insects have brief lives.
Plecoptera is an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, [1] with new species still being discovered. Stoneflies are found worldwide, except Antarctica. [2] Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and ...
Dobsonfly. 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 .
