Host plants:
The larvae are oligophagous on Fabaceae. For example Vicia, Lotus and Securigera varia are common host plants.
Habitat:
Euclidia glyphica inhabits nutrient-poor grasslands, extensively managed meadows, fens, Alpine meadows, pastures, broad forest edges and similar locations.
Life cycle:
The pupa hibernates. Adults are found from April to June, and in an often only partial but regular second generation from July to August. The adults feed nectar during the day on all sorts of flowers and are quite active in the sun. The eggs are deposited in small rows on blades. The caterpillar lives from June to September, partly still in early or mid-October.
Remarks:
Euclidia glyphica is widespread in Europe. In addition, it is also found in the Maghreb and in temperate Asia.
