Foodplant and Larval Feeding Signs
Mosses (species unspecified). The larva is undescribed but has been found in moss at the base of a tree; may also be associated with mosses away from trees.
Finding the Moth
Larva: undescribed in the British Isles but searches in mosses near or on the base of trees in April or May would be worthwhile. It is documented that a larva was bred through at Wicken Fen in 1878 (F. Bond) without description of the larva, feeding signs or foodplant.
Adult: swept from herb rich turf, beaten from scrub and frequent at light.
The broad forewing and hindwing with a lack of any prominent markings are distinctive. On a few occasions specimens of this moth have been found in historic Museum collections amongst specimens of Bryotropha politella.
Single brooded from early June to August and occasionally found in very small numbers in late May and through to late September.
