Leucoblepsis fenestraria is a moth in the family Drepanidae. It was described by Frederic Moore in 1868.[1] It is found in the north-eastern Himalayas, Taiwan and on Peninsular Malaysia and Borneo.[2]
Adults are whitish cinereous (ash grey), with two widely separated wavy brown lines from the abdominal margin to the costa before the apex. Between these on the forewings, is a diaphanous spot crossed by two veins. There is a submarginal and marginal row of white lunules, the former concave exteriorly and the latter interiorly and bordered by a brown marginal line.[3]
