The Mountain Small White likes warm and dry places, and is found on dry, poor grasslands, in rocky places, in open scrub and in large clearings in woods. The flight areas are usually on calcareous soil. The males can sometimes be seen in large groups on damp ground. Compared to other whites, this butterfly has a slow and measured flight. The main larval foodplant is Burnt Candytuft (Aethionema saxatile), but A. orbiculatum and Woad (Isatis tinctoria) are also used. The eggs are laid singly. The pupa is normally fixed to stones and rocks. There are two or three generations a year, and the pupa of the autumn generation hibernates.
