The meadow brown is a common butterfly. It is dark brown in colour with an eye-spot on each forewing. Females can be distinguished from males by the presence of an orange colouration on the forewings. In both sexes, the underside of the wings are paler in colour (2). The caterpillar is yellowish-green with a dark green underside, and is covered in long white hairs. A yellowish-white line passes along each side and the tail tapers into two whitish projections (3).
TopThe meadow brown is a univoltine species, which means that one generation is produced a year (3). The adults are on the wing from early June to late October, and females lay eggs either on blades of grass or in vegetation close to grasses (4). The eggs hatch after around three weeks and the caterpillars feed throughout the day, retreating down into the grasses in spells of cold weather (3). They overwinter among the grass stems and feed at night the following spring (4). The pupae are attached to grass stems during May, and adult butterflies emerge in around a month, starting the whole cycle once more (3).
TopWidespread and common in Britain but absent from Shetland. It becomes more of a coastal species in the north of its range (4). Elsewhere, this butterfly is found throughout Europe reaching east to Asia Minor and Iran (4).
TopAs the common name suggests, this butterfly was once closely associated with meadows. It is also found in downland, woodland rides, heaths, road verges and waste ground and is also found in urban habitats including gardens, parks and cemeteries (3) (4).
TopNot threatened (4).
TopAlthough this species is not threatened at present, populations have decreased in areas where agricultural intensification has taken place. Furthermore, the extent of hay meadows in Britain has declined massively, and the species cannot survive in areas where excessive grazing occurs (4).
TopConservation action has not been targeted at this common species.
