Scientific name: Pyrgus malvae
The Grizzled Skipper is a small, low-flying springtime butterfly with a striking black and white appearance.
It is found throughout England and Wales, but becoming increasingly rare. Its wings are black or dark brown, with a checker-board of white spots. The Dingy Skipper butterfly is similar in size, but its wings are much duller and some day-flying moths look similar when in flight.
The Grizzled Skipper is a characteristic spring butterfly of southern chalk downland and other sparsely vegetated habitats. Its rapid, darting style of flight can make it difficult to follow, but it stops regularly either to perch on a prominent twig, bask in the sun on bare ground for long stretches, or to feed on flowers such as Common Bird's-foot-trefoil or Bugle. It can then be identified quite easily by the checkerboard pattern on its wings.
The dome-shaped pale green eggs are laid singly on the undersides of leaves in warm spots near low vegetation or bare ground.
The emerging caterpillars are very small and yellow and can be found by the blotches left on leaves after they have fed. As it grows, its body becomes dark green, striped with brown. It makes a tent to live in by pulling the edges of a leaf over it with silk threads, as it mainly feeds in the early morning and evening, resting inbetween. This stage of its life lasts about two months.
The butterfly occurs across southern England, commonly in small colonies of less than 100. It has declined in several regions.In Wales it is restricted to the south coast and post-industrial sites in the north east.

Three main types are used by this butterfly:
- woodland rides, glades, and clearings
- unimproved grassland, especially chalk downland but also on other calcareous soils including clays
- recently abandoned industrial sites such as disused mineral workings, spoil heaps, railway lines and even rubbish tips
- occasionally it breeds on heathland, damp grassland, and dunes
