Dark Dagger Acronicta tridens ([Denis & Schiffermüller], 1775) 
Status .....Although it is extremely difficult to determine, Dark Dagger seems less common than the visually identical Grey Dagger. This means accurate separation of the two can only be done without examination of the genitalia, but the larvae of both species are easily told apart. Despite the differences, it seems larvae of many species are rarely recorded/reported, so it is with thanks that David Yates sent us a photograph of the larva below for identification and which he kindly allowed to be taken and reared out.
