Species Account

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.



Record Verification

Grade 3 adults are hard to separate from other species, so photos showing all critical ID features will be required, or in some cases a voucher specimen (seek advice before releasing the moth).
