Host plants:
The larvae are oligophagous on Fabaceae, such as Lotus, Vicia, Onobrychis or Hippocrepis.
Habitat:
Euclidia mi inhabits grasslands, extensive meadows, edges, pastures and other sunny, not intensely managed sites. It is found both in dry and wet habitats like fens.
Life cycle:
The pupa hibernates. The moths fly in May and June, especially during the day. They can easily be flushed and sit a few meters further back to the vegetation. Oviposition usually occurs in groups on blades and stems near the ground. I found the caterpillar sporadically in grasslands from July to August.
Remarks:
Euclidia mi is widespread in Europe and parts of temperate Asia.
