Host plants:
The larvae are polyphagous on herbs and low growing woods. I found caterpillars in November 2010 right on the edge of the water at a woodland stream on Scrophularia (Memmingen, Germany) and on Urtica on the partial nitrophytic and partial gappy-gravelly bank of the stream Rems near Schwäbisch Gmünd in late October 2011.
Habitat:
Naenia typica colonizes rather damp or wet areas such as shorelines of rivers and lakes and wet wooded areas. I found caterpillars also in the garden (near Memmingen, Germany) at a small garden pond and its surroundings, feeding for example on Vicia.
Life cycle:
The caterpillar overwinters and is mature in April or May. Adults can be found from June to August.
Remarks:
Naenia typica is mainly distributed from Central Europe to Central Asia.
