FRIDAY FLUTTER #35: Species Of The Week – Grizzled Skipper (Pyrgus malvae)
The Grizzled Skipper, is a low-flying, darting Butterfly species from the family Hesperiidae. It is a small attractive skipper with a chequered pattern on its wings. This Butterfly can be found throughout Europe and is common in central and southern regions of England and Wales but becoming increasingly rare. The wings are black or dark brown with a checkerboard pattern of white spots. The Grizzled Skipper is a characteristic spring Butterfly of southern chalk downland and other sparsely-vegetated habitats. Its rapid, buzzing flight can make it difficult to follow, but it stops regularly either to perch on a prominent twig or to feed on flowers such as Common Bird's-foot Trefoil or Bugle. It can then be identified quite easily by the pattern on its wings. The Grizzled Skipper has a wingspan of 2.3-2.9cm and is a fast flier, so is best observed in the morning as it basks in the sun to warm up. It favours chalk grassland and woodland habitats. It is a priority species under the UK Post-2010 Biodiversity Framework.
The Grizzled Skipper is the smallest of our skippers and the earliest to appear in spring. they require short, mixed vegetation that is usually created by grazing on chalk grassland or in woodland clearings. The caterpillars feed on a variety of plants, including wild strawberry, bramble, agrimony, salad burnet and creeping cinquefoil. The Grizzled Skipper wings have white fringes, with dark lines running through them, the Dingy Skipper is similar, but is larger and has lighter, duller wings. Although the Grizzled Skipper prefers unimproved chalk grassland and woodland rides, it has recently spread on to old industrial sites, such as mineral workings, spoil heaps, railway lines and even rubbish tips!
Eggs are laid on plants that will provide warmth and proper nutrition for development. As larvae, their movement is usually restricted to a single plant, on which they will build tents, unless they move onto a second host plant. Larvae then spin cocoons, usually on the last host plant they have occupied, where they remain until spring. Upon emerging as adult Butterflies, Grizzled Skippers are quite active during the day and tend to favour blue or violet-coloured plants for food. They also possess multiple methods of communication; for example, vibrations are used to communicate with ants, and chemical secretions play a role in mating. Exhibiting territorial behaviour, males apply perching and patrolling strategies to mate with a desired female.
With its characteristic wing pattern, the Grizzled Skipper is quite distinctive, although it closely resembles moths in appearance. Males and females can be differentiated by the shape of their wings: males have slightly more angular wings, while females have a more rounded wing shape. Larvae are coloured green and light brown with darker brown stripes. Seitz describes malvae "The terminal row of white dots developed, at least on the hindwing. The underside of the hindwing is reddish, with distinct white dots, those of the subterminal band being rounded, and veins that are bordered with yellowish white or white. They are on the wing in April and May and again from the end of July onwards, on sunny slopes, roads among fields and clearings in woods, being common everywhere in Central Europe but rare and elusive in parts of UK. The Grizzled Skipper is a very localised and declining Butterfly in Britain occuring in discrete colonies in open, sunny but sheltered, unfertilised grassland, woodland rides and glades or abandoned industrial sites, breeding where the vegetation is sparse and there are patches of bare ground. Best sites occur where there is a mosaic of short and long vegetation where the caterpillars feed on rosaceous plants such as Wild Strawberry, Creeping Cinquefoil and Bramble.
I personally had only ever seen one Grizzled Skipper many years ago when on a family outing, I hadn't seen any since then until I was on a BC field trip with friends - the target species were Pearl Bordered Fritillary and Grizzled Skipper, the latter refusing to make an appearance until we were leaving. As I walked away I saw one land near my feet and I just managed a very quick photo before it disappeared into the undergrowth - only one wing was in the photo due to the position it was in, but at least I saw and photographed it. Then a few weeks later I was on one of my field trips in a different location, looking for any spring Butterflies - and actually saw and photographed several Grizzled Skippers (such as the featured photo!)
Have you ever been lucky enough to see a rare and illusive Grizzled Skipper Butterfly?
