Mountain Clouded Yellow
Description:
The Mountain Clouded Yellow has its breeding ground in flower-rich alpine meadows. Although they are quick, strong flyers, they are not migrants and do not leave their habitat.
Various leguminous plants are used as larval food plant, including Horseshoe Vetch (Hippocrepis comosa), White Clover (Trifolium repens), Common Birdsfoot-trefoil (Lotus corniculatus), and vetches (Vicia spp.).
This butterfly species usually only has one generation a year, but in some years there is a partial second brood. The caterpillars hibernate after their second moult.
