The wingspan is 4.9–6.6 mm for males and 5–5.5 mm for females. Adults are on wing from July to August in the orient.
The larvae feed on Cyperus rotundus and probably Cyperus conglomeratus. They mine the leaves of their host plant. The mine starts either from the apex or middle of the leaf. The larva mines down for some length and then takes a turn and mines up, the second portion being exactly parallel to the first. The frass is deposited in a line in the center all along the mine. Pupation takes place in a flat, golden-yellow oval cocoon. The larva is yellow and transparent with a brown head.
(S . 4-5 mm) Head ochrcous-yellow, collar whitish. Antennae and eyecaps whitish. Thorax and abdomen light grey. Forewings lanceolate, light rather glossy grey; cilia whitish, tinged with grey on basal half, hindwings pale grey; cilia grey-whitish. Bengal, Pusa, in July and August (Fletcher); two specimens.— Original description by Edward Meyrick
