The Northern Brown Argus likes open grasslands or dry vegetation at the edges of woods. It is more closely bound to calcareous soil than the Brown Argus. The eggs are laid on various rockroses (Helianthemum spp.), as well as on various crane’s-bills (Geranium spp.). The caterpillars feed on the leaves, often attended by Lasius ants. When the caterpillars are half-grown, they hibernate. Pupation takes place in the litter layer. There is always only one generation.
