Large Wall Brown

Lasiommata maera

  • Family: Brushfooted Butterflies – Nymphalidae
  • Subfamily: Browns – Satyrinae
  • Wing span: Medium-sized, 42–53 mm (1.64–2.07 in.). Largest of its close relatives. Females usually larger than males.
  • Wing upper side: Brown, forewing apex with large eyespot, edge of hind wing with row of smaller eyespots. Eyespots mainly black with a white centre and surrounded by a reddish orange ring. Forewing possibly with reddish patches below large eyespots.
  • Wing underside: Forewing brown, tip with large eyespot, edge with red embroidery. Hind wing grey, centre with two long, brown wavy stripes and edge with row of black eyespots with white centre and surrounded by yellowish orange ring.
  • Habitat: Open forests with stones and rocky outcrops.
  • Flying time: Late June–mid-July.
  • Overwintering form: Caterpillar.
  • Larval foodplant: Different grasses (Poaceae), including some fescues (Festuca) and mannagrasses (Glyceria).

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.
