Cataclysta lemnata, the small china-mark, [2] is a moth species of the family Crambidae. It is found in Europe (including Great Britain and Ireland), [2] Morocco and Iran. [3]
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 scattered 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.
