Species Account

Sutton & Beaumont, 1989: There are one or two recent records from each vice-county except VC62.

2012 (CHF): There are occasional records in buckthorn-rich areas of south VC63, but our biggest populations are in the limestone Dales where large numbers (over 200 in a good year) can be found hibernating in caves. Buckthorn is present in these areas but is not common and it is not impossible that another food source is being utilised. Larvae have not yet been found in this area.
