Species Biology
Identification
Key identification features include:
- Medium size, wingspan: 46 - 56 mm
- Large haloed eyes towards rear of upper hindwing
- Cream blotches on upperside of wings
- Often found basking in pools of sunlight in partially shaded woodland or woodland edges.
Habitat
Generalist, found in tall-herb and grassy forest clearings, field margins, orchards, urban parks and gardens. Adults bask, roost and fly in areas of dappled sunlight, on edges of woodland or close to hedges on the margins of roads and paths (Bond & Gittings, 2008).
Flight period
Multivoltine with overlapping generations: typically, the 1st generation flies from April to June, the 2nd generation from July to September and a full or partial 3rd generation from August onwards.
Life cycle
Eggs are laid on the undersides of leaves of the foodplant, usually singly, occasionally in pairs. The hatching larva only sometimes feeds on the eggshell, but always stays close to it on the underside of the leaf, and feeds inwards from the leaf margin towards the midrib. After second instar, the larvae may wander between leaves. They feed intermittently both diurnally and nocturnally. During winter the larva usually spends larval diapause in the base of the grass stems, but is also capable of being active and feeding at temperatures above 6ºC. This species is unusual in that is may overwinter as a larva or a pupa (Bond & Gittings, 2008).
Food plants
Generalist, the larvae feed on a variety of grasses, but more commonly on False-brome (Brachypodium sylvaticum), Cock's-foot (Dactylis glomerata) and Yorkshire Fog (Holcus lanatus).
Flowers visited
Generalist, adults primarily feed on honeydew/sap, but nectars sources include: Bramble (Rubus fruticosus), Cuckooflower (Cardamine pratensis), Dandelion (Taraxacum agg.), Fleabane (Pulicaria dysenterica), Privet (Ligustrum vulgare) and Ragwort (Senecio jacobaea).
