Empria liturata
Thought to be widespread across much of mainland Britain, although records are difficult to assess precisely given inconsistencies in identification keys (Musgrove, 2023).
A black sawfly with pairs of white patches on tergites 2 to 5. Claws simple or sometimes with a tiny inner tooth. Antennal segment 8 is less than 3 times as long as broad. Front of clypeus only shallowly incised and with the outer teeth rounded apically. Tegulae usually black. Frontal furrow of the head reaches from ocelli to the antennae.
Note that in Benson's key, he states that Empria liturata male genitalia is as per tridens. However, this is incorrect (Prous, M. pers. comms.).
Empria liturata larvae feed on Meadowsweet, strawberries and avens.
