First Belgian record in 2020, probably overlooked in earlier years.
The larva mines at first in mainly Erica sp. Later it lives in a silken gallery amongst the leaves of Erica or Calluna vulgaris, close to the ground, and mainly feeds in mosses of the genus Cladonia. It can best be searched for in June–early July.
One generation a year: April–May.
Moors and heathland.
