Davey, P., 2009: A species restricted to drier habitats across Britain, the larva feeding on the stem bases of grasses (Poaceae). In Dorset, the moth is locally abundant on unimproved grassland on chalky soil, and frequent on dry heaths on sandy soil. Dr P Sterling has reared the moth from larvae found on bristle bent (Agrostis curtisii) on the heaths. A partial bivoltine tendency is suggested given early examples appearing during July.

This species is similar to Agriphila inquinatella1306. Diagnostics include: sharply-angled double chevron cross-lines on forewing.
