The Moorland Clouded Yellow occurs at the edges of raised bogs, and also on blanket bogs. At high altitudes, it is found in drier habitats. Eggs are laid singly on Bog Whortleberry (Vaccinium uliginosum). At first, the caterpillars only eat the upper layers of the leaf, producing “windows”, but later, the whole leaf is eaten. The caterpillars hibernate among the dry leaves of the litter layer, and the next spring feed and grow further, before finally pupating on a branch of the foodplant. It has one generation a year.
