A rather local species. Only found in large Calluna areas.
A very small species with brown-grey narrow forewings.
Wingspan is 6–8 mm.
The antennae are alternately ringed brown white till the tip.
This species makes a very small light brown case of about 4 mm. The mouth angle is 40°. The case is composed of 8–10 small leaf fragments, placed in a herringbone manner (see foto).

Caterpillars live from the autumn till May. Fully grown larvae are to be found from March till May.
The adult is day-active and rather hard to find due to its small size.

Large areas with Calluna.
