Clover Case-bearer Coleophora alcyonipennella: Distribution map

Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

Clover Case-bearer Coleophora alcyonipennella

(Kollar, 1832)

Wingspan c. 12mm.

Widely distributed across much of the British Isles, this species was formerly believed to be C. frischella but was correctly identified around the turn of this century.

It frequents rough grassy habitats, where the main foodplant, white clover (Trifolium repens) occurs. The larva feeds inside a case formed from a floret, and these are virtually impossible to see on the flower head. Larvae can be obtained by collecting the browning flowerheads and waiting for the larvae to detach their cases on the main flower head.

Adult moths fly in two generations, in May and June and again in late July and August.
