Alloplasta plantaria (Gravenhorst, 1829)

Alloplasta can be easily recognised through the wing venation; the nervellus is intercepted near or above the middle and the areolet is distinct.

In this species all coxae are black, distinguishing it from A. tomentosa . The tergites are also black, with a yellowish to whitish apical band and yellow patches on the face, distinguishing it from A. piceator ( KUSLITZKY, 1981) . Like many ichneumonids, this species is probably more common than data would suggest, with Orthosia cerasi (Fabricius, 1775) ( Lepidoptera : Noctuidae ) as an extremely common host (BROCK, 2017).

First report for the Netherlands; confirmed in Belgium.
