Nationally scarce (Nb) in fens, marshes, damp woodland, waste ground, gardens and on river-banks in England, as far north as Westmorland and Cumberland, but absent from south-west England and Wales (MBGBI Vol 4 part 1). First recorded in Hampshire in 2012, with another in 2018: however 2020 saw a record seven individuals, including the first for VC12 and the Isle of Wight, and it looks set to be a species that will increase in numbers annually. Wingspan 15-19 mm. Larva feeds on shoots and leaves of Common Comfrey, Tuberous Comfrey, Lungwort and Common Gromwell, beneath a silken web, over-wintering as a pupa.
