Stigmella circumargentea
Stigmella circumargentea is a moth of the family Nepticulidae. It is only known from Yunnan. The wingspan is about 6.2 mm. Larvae have been found in October; adults were reared in November. The larvae feed on "Lithocarpus dealbatus" and possibly "Lithocarpus mairei". They mine the leaves of their host plant. The mine consists of a long gallery, varying from sinuous to almost straight, with linear to dispersed frass filling the early mine, later the frass occupies about one third of the width of the mine.
