Species Account

Sutton & Beaumont, 1989: Widespread and often common in vice-counties 62 to 64 but few records for VC61 or VC65. This species may be less common than it appears since the proportion of A. tridens Denis & Schiffermiiller is at present unknown in most areas.

2012 (CHF): This species is probably widespread and common across all five vice-counties but as most records are submitted as "Grey/Dark Dagger" it is difficult to be sure. See comments under Dark Dagger. Grey Dagger is by far the commoner of the two species, especially on the higher ground.
