Marsh mallow moth  (Hydraecia osseola hucherardi)

Following a decline that started in 1966 (3), this moth is currently restricted to three sites in the Romney Marsh to Rye area on the border between Sussex and Kent, and a site in Kent on the bank of the river Medway (4). In Europe, the species occurs in only a few scattered sites (1).

The foodplant, marsh mallow, grows in damp, low-lying places along watercourses, field margins and ditches (4).
