Kent Moth Group


Pseudopostega auritella

Fen Bent-wing

Family: Opostegidae

RES: 5.003 B&F: 120

Verification Grade (Adult):

Very rare in Kent. Added to the Kent fauna with the surprise finding of a colony in the Orlestone, complex in 2020 (Boothroyd, B pers. comm. and Atropos: 66). Was previously restricted to a small number of sites in the fens and broads of Norfolk and Cambridgeshire.

Previously thought to have been a miner of the stems of Marsh Marigold, studies in the Netherlands (e.g. van Nieukerken, in 2006 Franje 9(17)) indicate that Gypsywort (Lycopus europaeus) is the food plant. This is borne out by field observations in Norfolk, and the site in Kent, where Gypsywort is abundant.

Foodplant: Gypsywort
