Species Biology

Identification

Key identification features include:

  • Medium size, wingspan: 40 - 60 mm
  • Two-toned grey-brown colouration on the underside of the hind wing, lacking any eyespots
  • One apical eye-spot and orange patch on upper- and underside of forewing

Habitat

Generalist, found on: unimproved dry grassland, wet grassland, improved grassland, coastal grey dunes, machair, dune slacks, field margins and urban parks. The adults usually roost relatively low in grasses and fly in grassland of a wide range of heights, but basking occurs only intermittently (Bond & Gittings, 2008).

Flight period

Univoltine: from May to September. Lack of synchronisation in larval development results in a prolonged flight season.

Life cycle

Eggs are laid singly on grass-blades but also often on dead vegetation or other nearby material. Several eggs are laid in a single bout on grass blades that can be quite close together. They then feed on the grass-blades from late September, with only partial winter diapause, until about the beginning of the following June. They feed by day until about March, after which they then feed after dusk, possibly partly as a result of the activities of insectivorous birds. When not feeding the larvae retreat to the bases of grass tussocks. Pupation occurs about the beginning of June, with the pupae hanging downwards attached to a silken pad on grass-stems or blades (Bond & Gittings, 2008).

Food plants

Generalist, the larvae feed on a variety of grasses, but more commonly on Meadow-grasses (Poa spp.), Bent-grasses (Agrostis spp.) and Tufted-grasses (Lolium  spp.).

Flowers visited

Generalist, adult nectar sources commonly include Knapweeds (Centaurea spp.) and Thistles (Cirsium spp. and Carduus spp.), but Bramble (Rubus fruticosus), Buttercups (Ranunculus spp.), Carline Thistle (Carlina vulgaris), Devil's-bit Scabious (Succisa pratensis), Fleabane (Pulicaria dysenterica), Hemp Agrimony (Eupatorium cannabinum), Knapweeds (Centaurea spp.), Marjoram (Origanum vulgare), Privet (Ligustrum vulgare), Ragwort (Senecio jacobaea), Selfheal (Prunella vulgaris), Teasel (Dipsacus fullonum), Thistles (Cirsium spp. and Carduus spp.) and Yarrow (Achillea millefolium) are also used.
