Main: (Erebidae / Toxocampinae)
72.070 [B&F: 2495] Olive Crescent (Trisateles emortualis) ([Denis & Schiffermüller], 1775)

 

Notes: A rare Red Data Book species, resident in a couple of localities in broad-leaved woodland and woodland clearings in southern England, and a priority species under the UK Biodiversity Action Plan. Historically records in Hampshire and on the Isle of Wight have been regarded as relating to immigrants from the continent but the 21st century has seen regular reports (2014 saw seven on the Isle of Wight alone) and it is probably now established as a very localised resident across the two counties. Wingspan 29-30 mm. Its light-coloured fasciae separate it from all other British Erebidae (MBGBI Vol 10). Larva feeds on Pedunculate Oak, Sessile Oak and Beech, over-wintering as a pupa.
