Panorpidae

Definition

The largest family of scorpionflies (order Mecoptera), comprising more than 480 species—approximately 70% of the order's diversity. Adults are slender, 9–25 mm in length, with elongated rostra and the distinctive recurved abdomen of scorpionflies. Larvae are eruciform and typically inhabit soil or leaf litter. The family is cosmopolitan in temperate regions and is the principal group associated with the common name "scorpionfly."

Etymology

From the type genus Panorpa (Greek pan- "all" + horpaō "to seize, carry off") + -idae (family suffix).

Example

Panorpa communis, a widespread European species, exhibits the classic Panorpidae morphology: black-and-yellow wings, an elongated rostrum with chewing mouthparts at the tip, and in males a bulbous, upturned terminal abdomen resembling a scorpion's stinger.

Usage Notes

Panorpidae is the type family of Mecoptera and the group to which the common name "scorpionfly" most strictly applies, though the name is sometimes extended to related families (especially Bittacidae, the hangingflies). The recurved male abdomen, while striking, is non-stinging and used in courtship and mating displays. Species identification relies heavily on male genitalic structures and wing venation patterns.
