Adults of the species are sexually dimorphic.[3] The wingspan is 18–19 mm for males and 22–24 mm for females. The forewings are white. The costa, discal spot and a series of terminal spots are all fuscous. The hindwings are white with scatted pale fuscous scales.[4] Meyrick describes it- The forewings in male are whitish, with a yellowish-fuscous discal dot, traces of lines, and a pale brownish terminal streak ; in female pale brownish, ochreous-mixed,with a darker discal spot, lines very indistinct, whitish, darker-edged, a whitish siibterminal streak. Hindwings are white; a dark fuscous discal dot ; lines outlined with fuscous, sometimes nearly obsolete, first preceded by a yellow or fuscous spot in disc ; subterminal and terminal ochreous lines enclosing a black fascia marked with four bluish-silvery dots.The larva is dark green or blackish ; dorsal line black ; head pale brown.[5]

The moth flies from May to August depending on the location.

Larvae are semiaquatic.[3] C. lemnata larvae have been recorded feeding on duckweed species (including Lemna species[3] and Spirodela polyrhiza[6]), as well as water ferns of the genus Azolla.[3] The species is known to pupate in cocoons[6] or shelters[3] built from plant material.
