Tipulidae

Definition

A large family of nematoceran flies (order Diptera) commonly known as crane flies, characterized by extremely long, fragile legs, an elongate slender abdomen, and a single pair of wings with reduced halteres. The family comprises more than 4,200 described species in over 30 genera, making it one of the most species-rich families of Diptera. Adults are typically crepuscular or nocturnal and are frequently mistaken for giant mosquitoes, though they do not bite; larvae are predominantly soil-dwelling and play significant roles in decomposition and as prey items in terrestrial food webs.

Etymology

From the type genus Tipula (Latin for 'water spider' or 'water measurer', possibly alluding to the insect's long-legged appearance) + -idae (family suffix).

Example

Tipula maxima, among the largest European crane flies, has a wingspan exceeding 60 mm and larvae that inhabit moist woodland soils where they feed on decaying organic matter.

Usage Notes

In contemporary taxonomy, Tipulidae is sometimes split into several families (Cylindrotomidae, Limoniidae, Pediciidae), with Tipulidae sensu stricto restricted to the 'large crane flies.' Check regional faunal treatments for current circumscription. The common name 'crane fly' is broadly applied to members of the superfamily Tipuloidea, not solely to Tipulidae.
