Host plants:
The caterpillars are polyphagous. They are often observed on Urtica dioica and Rubus idaeus.
Habitat:
Anaplectoides prasinanus colonizes at least slightly damp to wet forests, sometimes also larger humid scrub outside. In April and early May, the hibernated caterpillars are observed quite common with a pocket lamp at night along shady nettle edges, such as on roads and streams in the forest. The young caterpillars are easy to beat in the herbal layer at daytime in autumn (September to early November).
Life cycle:
The caterpillar overwinters and is mature in late April or early May. The moths fly from June to August.
Remarks:
In forests, Anaplectoides prasinanus is usually a quite common noctuid species. The distribution is Holarctic.
