Pyrus malvae
Grizzled Skippers are tiny butterflies that can be easily overlooked. Nationally, this species is in decline, but in Sussex it is doing reasonably well, as Wild Strawberry, its main larval foodplant, is a common wildflower on the South Downs. Colonies are usually small and rarely exceed 30 individuals.
Given a reasonable view it is not difficult to identify. The upperside is a charcoal background, on which there are well-defined scattered blocks of white, and on the margins of the wings there is a very bold black-and-white fringe.
The first adults usually emerge in the first two weeks of April, with peak numbers recorded in May. Territorial males bask prominently on bare soil or very short vegetation and dog-fights between neighbouring males are common. In truth, this tiny pugnacious butterfly is willing to do battle with just about any other butterfly that dares to fly over its patch. They are a joy to watch.
