Earwigflies

Definition

A small family of scorpionflies (order Mecoptera) characterized by males possessing prominent, forceps-like cerci that resemble the pincers of earwigs (Dermaptera). These nocturnal insects are found in moist woodland habitats in North America and Australia, where adults are typically encountered near decaying wood or leaf litter.

Etymology

From 'earwig,' referring to the resemblance of male cerci to earwig forceps, plus 'fly' (though not true flies, i.e., Diptera).

Example

The North American earwigfly Merope tuber has short, broad wings and reduced venation, while the Australian species Austromerope poultoni represents the only other extant genus in this relict family.

Synonyms

• Meropeidae

Usage Notes

Despite the common name, earwigflies are not flies (Diptera) but scorpionflies. The family is notable for its disjunct distribution and probable Gondwanan origin. Only two extant genera are recognized, making this one of the smallest families of Mecoptera. The forceps-like cerci are used in male-male competition and possibly in mating.
