Upper Valais 2012) [S] Eugnorisma depunctum: Larval habitat in the Allgäu Alps in 1600m above sea level: herb community with tree groups. Here also occur Boloria titania, Boloria thore and Parnassius mnemosyne. May 2009. [N]

Host plants:
The larvae are polyphagous in the herbal layer and on low growing bushes. I found many larvae in a habitat of Parnassius mnemosyne on Corydalis cava (May, 1600m above sea level, Allgäu). In the Upper Valais, I found a larva on Vaccinium myrtillus in 1800m above sea level in June 2012.

Habitat:
Eugnorisma depunctum inhabits woodland clearings and edges, hedgerows, bushy rocky slopes and similar grove rich habitats.

Life cycle:
The caterpillar overwinters without having fed and develops particularly in April and May (at high altitudes until the beginning of July). The moths fly in late summer.

Remarks:
Eugnorisma depunctum is widespread in Central and Southern Europe as well as Western Asia, but with a gap in the northwest of Central Europe (Benelux and Northern France). Similar forms are found in the Iberian Peninsula and in Morocco, but they are regarded today as separate species.
