The eastern dobsonfly,
Corydalus cornutus, is the most well-known
North American
species among the dobsonflies. These
genera have distinctive elongated mandibles in males and form the
subfamily Corydalinae. The genera in which the males have normal mandibles, called fishflies, form the subfamily
Chauliodinae. The summer fishfly,
Chauliodes pectinicornis, is perhaps the best-known of these in North America; its immense mating swarms in the
Upper Mississippi River region fill the air on a few summer nights each year much like
mayflies in certain regions of
Europe, leaving millions of carcasses to be cleaned up the next day. File:Chauliodes rastricornis P1400671a.jpg|
