Nationally scarce (Nb) in parks and gardens in parts of south-eastern England. An adventive species, naturalised through accidental introduction on coniferous plants from southern Europe and now fully established. In Hampshire most records are from the Portsmouth area. Not recorded from the Isle of Wight to date. Wingspan 10-13 mm. Can be distinguished from other superficially similar brown gelechiids using external characteristics only with great care. Larva mines leaves of Juniper and Lawson's Cypress, subsequently living within a silken tube or tent.
