Entephria flavicinctata (Hübner, [1813])

Entephria flavicinctata: Adult (e.l. Valais, Switzerland) [S] Entephria flavicinctata: Adult [S] Entephria flavicinctata: Larva (Wallis) [M] Entephria flavicinctata: Larva [S] Entephria flavicinctata: Pupa [S] Entephria flavicinctata: Habitat in the Swiss Valais on 2000m above sea level: top of the wall in the right side (2009). In den wall gaps I observed many larave of Nudaria mundana. [N]

Host plants:
The caterpillar feeds on various species of Saxifraga. Besides apparently also Sedum is accepted. I found the caterpillar in Valais in over 2000m asl on top of a wall on Saxifraga aspera.

Entephria flavicinctata inhabits halfshady, slightly moist rock and rubble sites in the Alps and other mountain ranges from 600 to 2500 meters above sea level.

Life cycle:
The caterpillar overwinters and is mature at low altitudes in April, but in higher ones not until early or mid-June. The moths fly from June to August. Less commonly, a partial second generation occurs in low elevations or in mild areas.

Endangerment factors:
In the medium high mountains, Entephria flavicinctata is highly vulnerable because of expansion of dark, dense coniferous forests. But it is hardly at risk in the high mountains on the other hand.

The distribution is very disjointed and extends across the Pyrenees, the Alps, some lower mountains ountain (Vosges), Iceland, the UK and locally from Norway across the Arctic zone to northern Russia.
