Notes

Remarkably, this species has over 1500 records on GBIF, but records of hibernating specimens are extremely rare. The species is included in Berthoumieu (1895 b) as a hibernator, but this was only confirmed in 2014. This may demonstrate diapause is rather facultative and / or the hibernaculum is limited to tussocks or very specialised. In the Netherlands, one specimen was observed feeding on bait (used for moths) on 16. II. 2023 (Observation. org). Additionally, in Austria, a specimen was collected on 15. XII. 1927 (GBIF).

Status: Confirmed.

Records: Belgium (1) *, France (2), United Kingdom (1) *.

First record: Ca. 1895 ( Berthoumieu (1895 b), France).

Hibernacula: DT (2), LV (1), M (1).

Sources: Berthoumieu (1895 b) [ Amblyteles oratorius Fabr. ]; Unpublished: Coll. RBINS, Pers. obs.
