Host plants:
The larvae are polyphagous on herbs and shrubs. I found each one batch of eggs on the underside of leaves of Salix caprea and Ulmus glabra (Prättigau, eastern Switzerland).
Habitat:
Lacanobia w-latinum occurs in a variety of habitats from forest edges to grasslands.
Life cycle:
The pupa hibernates. The moths fly in May and June, sometimes even in July. The caterpillars are found from July to September. Probably a partial second generation is performed in favourable sites (July/August).
Remarks:
Lacanobia w-latinum is widespread in Europe and temperate Asia.
