Gorse Case-bearer - Coleophora albicosta

Phylum: Arthropoda - Class: Insecta - Order: Lepidoptera - Family: Coleophoridae


This common moth derives its Latin name from the white streak along its forewing.

Although predominantly a day-flying moth the Gorse Case-bearer can be attracted by light during darkness. It is on the wing during June and July.

The wingspan of the Gorse Case-bearer ranges between 14 and 16mm.


Coleophora albicosta is common and widespread throughout the UK and Ireland.


The Gorse Case-bearer over-winters in a silk cocoon contained within a dead gorse flower and then pupates from the case in early April. The larvae of the moth feed on Gorse seeds inside the seed pod, and then live in a case fashioned from a flower sepal which it attacheds to the side of a seed pod.

The larval foodplant of this moth is Gorse (Ulex europaeus)
