Species Account

Davey, P., 2020: Twin-spot Plume Stenoptilia bipunctidactylus: A species found widely across the UK, the larva feeding on field scabious Knautia arvensis, small scabious Scabiosa columbaria, and devil’s-bit scabious Succisa pratensis. In Dorset, this species is found very locally within unimproved grassland, chiefly on alkaline soils.

1508D Scarce Plume Stenoptilia inopinata: A rare immigrant to Britain with just a handful of records that have ever been confirmed, mainly from southern coastal counties. It has been recorded twice in Dorset, in Purbeck in 1899 and Walditch in 2013. The larva feeds on Chaenorhinum rubrifolium, a relative of toadflax not found in the British Isles.
