Agrothereutes leucorhaeus (Donovan, 1810) (Fig. 23)

Agrothereutes leucorhaeus is harder to identify than A. aterrimus . Its hind tibiae are white basally, the hind tarsi do not have a white ring (females), its face has white orbits (but is black medially) and its clypeus has white spots (SCHWARZ [2013], draft key; see Fig. 23). Just like the abovementioned species A. aterrimus , most of the observations were made in gardens. One observer was able to rear several specimens from a cocoon of Lasiocampa quercus ( Lepidoptera : Lasiocampidae ), thus confirming the existing host record in literature ( QUICKE & SHAW, 2004). First report for the Netherlands; confirmed in Belgium.
