Sutton & Beaumont, 1989: This is a species which is locally common in the very south of England but which sporadically turns up in other parts of the country. In Yorkshire, it was first found at Spurn (VC61) by H. N. Michaelis in 1949 (YNU, 1970; also included in Michaelis, 1951 but no date or comment). There have been several other records at the same site since. These are 10.6.1970, 6.8.1975, two 23.7.1983, singles 6.7, 19.8 and 22.8.1984 and 6.7.1987 (BRS).
