1345 Brown China-mark Elophila nymphaeata
(Linnaeus, 1758)Wingspan 22-30 mm.
The group of moths known as China-marks are unusual in that their larvae are entirely aquatic, feeding on water plants.
This species is quite variable, and some examples are quite dark and dull-looking, whereas others can have delicately-patterned white patches and streaks.
The moth flies in July and August, and the species is fairly common around ponds, lakes and canals throughout Britain.
