Morley’s Final Catalogue: Occurs among black-knapweed at Tuddenham (Wrn). Bred trom Carduus arvensis at Bentley (Whit).
Recent Status: Well recorded in Suffolk. The Morley records appear suspect.
Life Style: This is a double brooded species that flies by day and night and comes to light. It can be found from May to September. The larvae feed in the unripe seeds of Trifolium repens and C. hybridum. They construct a case from a flower petal in their later instars. They pupate on the flower or the ground.
Identification: One of our bronze Coleophora species that can be identified from the imago. The identification is based on the small size and the antennae which are not thickly clothed with scales basally, are not ringed and are dark with a white tip. The description of C. frischella in Moths and Butterflies of Great Britain and Ireland is of C. alcyonipennella but the genitalia images are for C. frischella. C. frischella has not been found in Suffolk and is quite rare in the UK. More Info
