I KEPT THINKING of the patterns on sea-shells as I drew this moth, the mother of pearl, Pleuroptya ruralis. At 15-17 mm, three-quarters of an inch, it’s no midget but it’s classified as a micro-moth, one of the Crambidae, a group which also includes grass-moths, china-marks and the small magpie.
You might disturb the mother of pearl in daylight in a nettle patch. Its green larva rolls a nettle leaf for protection. Its larvae will also feed on elms.
Caught in the moth trap 21-22 July.
