Description and notes
Previously known as H. intermedium, a misidentification. Identification keys and general biology are given in Morgan (1984), Falk (1991) and Kunz (1994).
There are two records from England: from Lyndhurst, Hampshire (Morice 1901b) and from Wandsworth, Surrey (Morice 1902). The Lyndhurst specimen has been found at Oxford University Museum. Now regarded as extinct in England, but still found on Jersey and Guernsey.
Overseas found throughout Europe except the extreme north (including Finland, Denmark, The Netherlands, France including Corsica, Spain, Portugal, Germany, Switzerland, Poland, Austria, Hungary, Albania, Greece), and in Turkey, Armenia, Iran, Siberia and north Africa.
