Pyrgus malvae Linnaeus, 1758

The Grizzled Skipper flies very rapidly, usually very close to the ground, and is extremely difficult to follow in flight. As a result of it's small size, rapid and erratic flight pattern, and lack of bright colours it is easily overlooked and certainly under-recorded.
It is distributed throughout most of Europe from northern Turkey, across temperate Asia to northern China and Korea.
The sexes can be distinguished easily - males have a fold along the leading edge of the forewings. This fold contains androconia which release pheromones. Over a period of several days these become exhausted. Females are able to assess the age and virility of the males by "reading" the strength of the remaining pheromones.
Both sexes are prone to variation in the size and extent of the white markings. The ground colour is deep black when the butterflies are freshly emerged, but quickly fades to a dark earthy brown. At a few sites a recessive gene causes the periodic appearance of an aberrant form known as taras, in which the white markings on the forewings are greatly elongated and enlarged.
The flight season is greatly affected by climatic conditions in early spring. In forward seasons the butterflies can appear in early April, but they may not emerge until May in a late season. Numbers tend to build up gradually throughout May, and in late seasons the butterfly can often still be found in mid-June. In Europe there is a partial 2nd brood emerging in August.
The greenish white dome-shaped eggs are laid singly in April and May on the undersides of leaves of wild strawberry Fragaria vesca, creeping cinquefoil Potentilla repens, tormentil P. erecta, or agrimony Agrimonia eupatoria. More rarely young suckers of bramble Rubus fruticosus may be used. The eggs hatch after about 10 days.
When small, the caterpillar is yellowish, and rests under a thin veil of silk spun over the midrib on the upper surface of leaves. It produces characteristic blotches nibbled out of the upper cuticle. When older it lives within a folded leaf spun together with a few strands of silk. The fully grown larva is green with narrow brown stripes along the back and sides.
Pupation takes place in August. The pupa is formed within a thin net-like cocoon spun near the base of the foodplant. It is very distinctive, with the abdomen and thorax dark brown, and the wing cases greenish white. The pupal stage lasts from August until the following April or May.
