Range & Status
Apparently rare, though the host plant Dropwort Filipendula vulgaris is locally frequent on calcareous downland in southern England. There are records from east Gloucestershire, South Devon, Worcestershire, Yorkshire and Cornwall. There are two recent records from the Lizard Peninsula: Kynance Cove (The National Trust) 1972 and Nankidden 1982. Dropwort is a rare plant in Cornwall in general, but it is abundant on the Lizard Peninsula growing in soil overlying the ultrabasic serpentine rock.
