The large wall brown is fairly common in central and southern Finland, and can be separated from other browns (except northern wall brown) by the large eyespots on the upper surface of the apex of the forewing.
Males usually fly around looking for females, but especially on warm days they can also wait for females, defending their territory in forested areas close to large stones and bushes, and often on top of hills. The females lay their eggs individually on broad-leaved grasses.
