Pediciidae

Definition

A family of small to medium-sized flies (order Diptera) commonly known as hairy-eyed craneflies, closely related to the true crane flies (Tipulidae). Members are distinguished by their pubescent compound eyes and reduced wing venation compared to Tipulidae. The family comprises approximately 500 described species worldwide, with larvae typically found in moist terrestrial habitats, decaying wood, or aquatic environments where they function as detritivores or predators.

Etymology

From Latin pedico (comb, relating to hair) + -idae (family suffix), referring to the hairy eyes characteristic of this group.

Example

Pediciid larvae in the genus Pedicia are frequently collected from saturated moss and seepage areas in temperate forests, where their elongated, leathery integument distinguishes them from tipulid larvae sharing the same microhabitat.

Synonyms

• hairy-eyed craneflies

Related Terms

• Tipulidae
• Diptera
• Nematocera
• Pedicia
• cranefly
• limoniid

Usage Notes

Pediciidae was historically treated as a subfamily of Tipulidae but is now widely recognized as a distinct family within the superfamily Tipuloidea. The common name 'hairy-eyed craneflies' refers to the dense setae on the compound eyes, a synapomorphy visible under magnification; this trait contrasts with the typically glabrous eyes of Tipulidae. Specialists may encounter this family in aquatic macroinvertebrate surveys and forest soil fauna studies. The family is sometimes confused with Limoniidae, another tipuloid family separated by subtle characters of wing venation and male genitalia.
