Thysanoplusia orichalcea (Fabricius, 1775) Species

Last modified: Dec. 28, 2023, 12:47 p.m.

First observation for Belgium in OV in 2021, which was clearly an imported specimen. However, in 2023, the species also seems to have reached our country as a migrant, just like in our neighboring countries.
