First observation of this very rare migrant for Belgium was in autumn 2019 in WV.
Known specimens in Belgium: 2019 (1 WV), 2020 (1 LG), 2022 (1 WV).
Larvae can be found year-round and live quite concealed near the ground at daytime.
Adults are on the wing year-round, but most vagrants are seen during autumn.
Species seen in Belgium were in late October and early November.
The larva is polyphagous on grasses and herbs like various Poaceae, Trifolium, Rumex, Oxalis, etc...
It inhabits especially humid to wet places with dense, but more short growing vegetation.
