syn. Campoplex rufimanus Gravenhorst, 1829 : Horstmann (2000)

syn. Limneria oculata Tschek, 1871 : Hinz (1957)

A large species, in comparison with other species running to the same section of the key. The tegula is usually blackish in the female, and may be yellow or blackish in the male, or almost any shade in-between. The centre of the metasoma is a rich red colour, often with a varying amount of irregular blackish wash darkening parts of it. The sixth and seventh tergites are always black. The areae externae and the proximal part of the area superomedia of the propodeum are finely granulate, contrasting with the strongly rugose sculpture of the rest of the propodeum.

A parasitoid of moths of the erebid subfamily Arctiinae , including Arctia caja (Linnaeus) , Coscinia striata (Linnaeus) , Cymbalophora pudica (Esper) and Spilosoma lutea (Hufnagel) ( Shaw et al. 2016) . We have seen specimens from the UK, Spain and Germany. It has been reported from most European countries as far east as Ukraine, and also from Tunisia. Phenological data shows specimens taken from March to September, in every month except July; rearings suggest that it is plurivoltine, overwintering in the host larva ( Shaw et al. 2016).
