Explanation of Names
MEROPE: In Greek mythology, Merope was one of the seven Pleiades, daughters of Atlas and Pleione. In astronomy, Merope is one of the stars in the cluster Pleiades (AKA "seven sisters") in the constellation Taurus. I don't know the significance of the name.
TUBER: refers to the tuber-shaped lobe, or jugum, at the base of the forewing along the hind margin.
Numbers
the only species in this genus in the world
uncommon to rare in much of its range, never present in large numbers, poorly represented in insect collections, and seldom encountered in the field
Identification
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
known only from eastern North America (Quebec, Ontario, and Maine to Georgia, west to Texas and Oklahoma, north to Minnesota)
has been recorded in the United States from AR DC GA IA IL IN KS KY MD ME MI MN MO NC NJ OK PA TX VA WI WV, and in Canada from ON & QC
Habitat
in low vegetation or on the ground in densely-vegetated woodlands, often near water or wet seeps (similar to scorpionfly habitat); adults are nocturnal and are attracted to light
Life Cycle
Very little is known about biology or behavior. Larvae have never been discovered.
Remarks
A distinct lobe, or jugum, is present at the base of each forewing along the hind margin. The undersides of the juga are serrated, and can be rubbed against a serrated portion of the thorax to allow production of sound (stridulation), which typically occurs as a defense behavior when disturbed, but also could be used to communicate with the opposite sex.
