Species Account


Sutton & Beaumont, 1989: Frequent to common in all five vice-counties. This species is known for its habit of congregating in crevices in buildings and old trees and scuttling away rather than flying when disturbed, hence the English name.

2012 (CHF): Widely distributed across the county in good numbers but records may have declined a little recently. The biggest catches have usually been from Spurn but it is not as common there as it was 20 - 30 years ago.
