Species account (old)

[...] In Robson's time there was a flourishing colony around Hartlepool, reaching up the coast to beyond Blackhall Rocks. Robson describes it as swarming in this area, the only known colony [...] at that time [...] It was seen again on the Blackhall Coast in 1931 by J. W. H. Harrison Vasculum Vol. 17; 118) and more recently still a specimen was taken by R. Woods at the same site in June 1986. Apparently it still survives in this Durham locality although it is very scarce.
