Yorkshire Status: Common and widespread resident.

Grey Dagger appears to be 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. All the dots on the map are either larva or adults which have been checked. Grey Dagger is by far the commoner of the two species, especially on the higher ground. It is difficult to give figures on how well this species is doing in the county, but in general, numbers of the aggregate species are very healthy at the moment. The larvae are often reported, and have been seen on at least 12 species of broad-leaved trees and shrubs in Yorkshire.

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.
