Host plants:
The caterpillar lives on Ribes species (gooseberry, more rarely also currant).
Habitat:
Macaria wauaria inhabits forests, bushy grasslands and hedge areas with the larval food. It penetrates even in gardens.
Life cycle:
The egg hibernates. Caterpillars are found from mid-April to early June (nowadays especially from late April to mid-May). The moths fly mainly in June and July, rarely already in late May or still in early August.
Remarks:
The distribution extends from Morocco across Europe to east Asia and locally North America (Holarctic distribution).
