2 species in the world [the other species, Austromerope poultoni, occurs only in southwestern Australia]
Identification
size and shape of male claspers is unique
body yellowish-brown; wings divided into many rectangular cells by numerous cross-veins; male with elongate, slender clasping structures at end of abdomen; female abdomen shorter, tapering to narrow tip
Range
Quebec, Ontario, and Maine to Georgia, west to Texas and Oklahoma, north to Minnesota
Habitat
densely-vegetated woodlands, often near water or wet seeps (similar to scorpionfly habitat); adults are nocturnal and attracted to light
Life Cycle
Very little is known about the biology or behavior of meropeids. Larvae of Merope tuber have never been discovered.
Remarks
The family was widespread in the Jurassic period from Australia to Antarctica, and from North America to South America. Merope tuber and Austromerope pultoni are ancient species left at the edges of the former range.
