Alexander, 1943
Ptychoptera sculleni is a of phantom crane fly in the Ptychopteridae, described by Alexander in 1943. It is one of several North American species in a characterized by distinctive aquatic larval stages and aerial with long, spindly legs. The species is restricted to the Pacific coastal region of the western United States.

Identification
can be distinguished from other Diptera by the combination of long, slender legs, a relatively small body, and wing venation typical of Ptychopteridae. Separation from such as P. minuta and P. westermanni requires examination of male genitalia and specific wing characters; P. sculleni is known from the Pacific states rather than eastern or central North America.
Habitat
Larvae develop in aquatic or semi-aquatic environments, including shallow streams, seeps, and wet organic substrates. are found in riparian and moist woodland areas near larval development sites.
Distribution
Pacific coastal region of the western United States: California, Oregon, and Washington.
Life Cycle
Like other Ptychoptera, this has an aquatic larval stage and aerial stage. Specific details of , larval, pupal, and adult duration for this species are not documented.
Behavior
have been observed with a characteristic hovering pattern, moving slowly with long legs trailing. This flight is typical of phantom crane flies and aids in mate location.
Ecological Role
Larvae contribute to decomposition and nutrient cycling in aquatic and semi-aquatic . serve as prey for aerial including birds and spiders.
