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)
