Black Hairstreak

Satyrium pruni

A single male was caught on a railway embankment near the Fosse Way between Harbury and Leamington Spa in 1928. This is the only known record for Warwickshire.

Smith, R. and Brown, D. (1979) states that in the supplement to Donovan's Catalogue of the Macrolepidoptera of Gloucestershire, reference is made to the Black Hairstreak being "present at Walford Wood in 1877". It goes on to say that a Mr A. Richardson states that "... the species still occurs freely near Oxford and in Warwickshire". It should be noted that it is likely that Mr A. Richardson confused the Black Hairstreak with the White-letter Hairstreak.

Habitat Requirements

The Black Hairstreak has very specific environmental requirements. Colonies tend to breed year after year in the same small area of habitat, with individuals rarely wandering far from the main colony. It prefers dense, mature stands of blackthorn, growing in sheltered positions alongside rides and clearings in woods and woodland edges.
