Explanation of Names
CONDYLOLOMIA: a condyloma is a wart-like growth on the skin; from the Greek "kondylos" (a knob, knuckle) + "omos" (raw, like a tumor); probably refers to the raised oblong "growth" along the costa of the forewing, present in many adults
the only species in this genus in North America (and the world?)
wingspan 12-15 mm.
Adult: distinguishing feature (absent in some individuals) is a raised oblong "growth" along forewing costa in antemedial area; forewing dull yellowish-brown or gray, sometimes suffused with red or pinkish-purple; AM and PM lines dark, diffuse, indistinct; PM line bordered distally by dull yellowish line, most noticeable at costa; hindwing brownish-gray with thin dark terminal line
southern Quebec to northeast Georgia, west to Nebraska and Minnesota
bogs and swamps where the presumed foodplant grows; adults are nocturnal and come to light
adults fly in June and July
larvae have been found inside rolled leaftips of Sweet Gale (Myrica gale)

When present, the warty growth on the forewing (males?) is very distinctive. When it is lacking or inconspicuous, identification is more difficult.

Arta olivalis has AM and PM lines more distinct, PM line closer to outer margin, PM area concolorous with median and AM areas, and yellow at distal end of fringe in fresh specimens.

Parachma ochracealis has scale tufts on the tarsi and femora and yellow fringe.

Basacallis tarachodes has scale tufts on femora, usually has darker median area and AM area and PM area concolorous, has scale tufts on femora, and has yellow and red fringe.
