  Introduction  

Like most skippers, the Grizzled Skipper is extremely difficult to follow when in flight, but will stop to feed from various nectar sources. Once settled, the black and white pattern on the wings, from which this species gets its name, is unmistakable. The butterfly occurs in small colonies of less than 100 adults. A well-known aberration of this species, ab. taras, has all of the white spots on the forewings joined, forming a large white blotch. This butterfly is found in England south of a line extended from West Gloucestershire in the west to North Lincolnshire in the east, with strongholds in central and southern England. There are scattered colonies further north and in Wales. This species is absent from Scotland, Ireland, the Isle of Man and the Channel Islands.

Pyrgus malvae

This species was first defined in Linnaeus (1758) as shown here (type locality: Sweden).

  Phenology  

The butterfly emerges in late April and flies until the end of June. There is one generation each year, although there may be a small second brood in some years, when weather conditions are favourable.


The chart(s) above have been correlated with the phenology plot below, taken from the UK Butterfly Monitoring Scheme. The blue line gives average counts over the full data set from 1976 to date, and the red line gives the average for the last year.


  Habitat  

This species occurs in different habitats that are all characterised by warmth, shelter, and sparse vegetation, such as chalk downland, woodland edges, woodland clearings, large woodland rides, unimproved grassland, hillsides, valleys and occasionally heathland.

  Larval Foodplants  

The primary larval foodplants are Agrimony (Agrimonia eupatoria), Creeping Cinquefoil (Potentilla reptans) and Wild Strawberry (Fragaria vesca). Barren Strawberry (Potentilla sterilis), Bramble (Rubus fruticosus), Dog-rose (Rosa canina), Salad Burnet (Sanguisorba minor), Tormentil (Potentilla erecta) and Wood Avens (Geum urbanum) are also used.

  Nectar Sources  

Adults feed primarily on Bird's-foot Trefoil (Lotus corniculatus), Bugle (Ajuga reptans), Buttercups (Ranunculus spp.) and Ragged Robin (Lychnis flos-cuculi).

  Imago  

This is a warmth-loving butterfly, and both sexes bask in the sun for long periods, typically on a stone, leaf or bare earth. This is an active butterfly which will fly at most times the day, and even into the evening, if conditions are warm enough. The butterfly uses several nectar sources, favourites being Bird’s-foot Trefoil and Buttercup. The male is somewhat territorial and will chase any butterfly, irrespective of size, from its area. Females entering the territory are courted for a short period and, if the female is receptive, pairing occurs. The butterfly can be found roosting on heads of flowers and grasses during cool weather and at night.

  Ovum  

Eggs are laid singly on the underside of a leaf. Foodplants growing in warm positions, next to bare ground or short vegetation, are favoured. This stage lasts around 10 days.

  Larva  

The larva eats the crown of the egg on hatching, and immediately moves to the upperside of the leaf, where it spins a web of silk across the midrib. The larva feeds on the leaf surface at first, leaving the leaf structurally intact. The larva moves to a new leaf, creating a new web, as necessary. In the 3rd instar, the larva creates a larger shelter by either spinning the edges of a leaf together, or by spinning two leaves together. The larva feeds primarily in early morning and evening, and spends a great deal of time resting, rather than feeding. Development is therefore relatively-slow, lasting around 2 months.

  Pupa  

When fully-grown, the larva constructs a loose cocoon at the base of the vegetation, often among stems of the foodplant. The pupa is formed within the cocoon, secured by protrusions on the body and the cremaster, where it overwinters, this stage lasting around 9 months.
