Nationally scarce (Nb) in two distinct ecotypes: on woodland edges, heaths and hedgerows (Oak); and on moorland, fens, bogs, damp heathland and mosses (Bog-myrtle). Found throughout the British Isles, but not recorded from the Outer Hebrides, Orkney or Shetland. The race feeding on Oak predominates in southern England, that on Bog-myrtle in northern England and Scotland (MBGBI Vol 4 part 2). In Hampshire very sparsely recorded: in the south at Botley Wood, Browndown, Southsea and Chandler's Ford; in the north at Yateley and Mortimer. Not recorded from the Isle of Wight to date. Wingspan 11-12 mm. The most likely confusion species is
Teleiodes wagae, which see for differences. Larva feeds on Oak or Bog-myrtle, living between leaves spun together with silk, over-wintering as a pupa.
