Host plants:
The caterpillar is polyphagous, but prefers Fabaceae such as Onobrychis and Lotus.
Habitat:
Scopula immorata colonizes at least in places knee-high growing extensively grazed grasslands and extensively managed meadows. Sometimes it is also observed in grassy clearcuttings.
Life cycle:
The caterpillar overwinters. The moths may be encountered in two generations from May to early July and from mid-July to August. Above 500m asl it is obviously often largely limited to only a single generation from late May to early August, although few moths of a partial second generation are observed from August.
Endangerment factors:
Scopula immorata is in decline due to the huge reduction of extensive meadows. But it is steadily occurring on remaining grasslands.
Remarks:
The spread ranges from Spain to Mongolia.
