Lithosia quadra (Linnaeus, 1758) Species
Last modified: Sept. 13, 2023, 11:58 a.m.
A very rare species in Belgium, mostly known from the southern provinces. Used to be known from some localities in the north, but on 13 September 2006, there was a great influx of this species all over the country. It was observed again in BR (formerly only known from literature) and in AN. (last observation was in 1951!) and the species was new for the provinces of LI and WV.
A species that sometimes can occur in great numbers with migratory movements. Nowadays (2018) a not so common species in the whole country with most observations still in the south where it can be locally common.
