Cocksfoot Moth

The cocksfoot moth (Glyphipterix simpliciella) is a tiny moth in the family Glyphipterigidae with a wingspan of only 6–8 millimetres, native to temperate grasslands and meadows across much of Europe, including Belgium, Denmark, Norway, and Sweden, as well as parts of Asia. Adults are attractively marked with silver and orange-brown scales on the forewings, making them conspicuous despite their small size when they fly in the sunshine of meadows and grassy areas from May to July. The species is closely associated with cocksfoot grass (Dactylis glomerata), the larval food plant after which it is named. Females lay eggs in the spikelets of cocksfoot and other grasses; larvae develop within the seed heads, feeding on the developing seeds, before pupating in the grass tussock. Adults are diurnal, basking and flying on warm days and often observed resting on grass stems with wings held roof-like over the body. Glyphipterix simpliciella is widespread in grassland habitats from lowland meadows to upland pastures and is one of the more frequently encountered members of its family across its European range. It is classified as Least Concern by the IUCN, with stable populations supported by the wide distribution of its grass hosts across managed and semi-natural grasslands. The species is considered a useful bioindicator of species-rich traditional grasslands in parts of its range.
