Host plants:
The caterpillar lives polyphagous on deciduous woods such as Salix, Rubus and Prunus. I found them on the Swabian Alb and the Upper Rhine on oak (Quercus).
Habitat:
Hypomecis punctinalis inhabits deciduous mixed forests and generally habitats rich in deciduous woods up to the villages and towns. I found the caterpillar, for example, on south-facing forest edges (Upper Rhine) on oak and the moths in the margin area of the city of Schwaebisch Gmuend.
Life cycle:
The pupa hibernates. The moths fly in mostly an elongated generation from late April to late August/early September. Rarely moths of a very partial second generation occur in August and September. The caterpillar lives from late May to September or early October.
Remarks:
Hypomecis punctinalis is widespread in Europe and temperate Asia, with the exception of the far north.
