Aptesis nigrocincta

Description

Aptesis nigrocincta (Gravenhorst, 1815)

Notes

Aptesis nigrocincta is specialised on sawfly hosts, for example, the apple sawfly Hoplocampa testudinea (Klug, 1816). This host association is more exceptional within hibernating Ichneumonidae, but it is possible that the diapause is facultative here. However, the species has been found in a wide variety of hibernacula and countries, with a slight preference for hibernation in vegetation, notably grass tussocks.

Status: Confirmed.

Records: Belgium (2), Denmark (1) *, France (1), Ireland (4), Norway (4), Russia (1), Sweden (1) *, Switzerland (1) *, The Netherlands (2) *, United Kingdom (13).

First record: 13. III. 1904 (Morley (1907), United Kingdom).
