Skippers, Family Hesperiidae

A distinctive family of small butterflies with

40 representatives in Europe. These mostly

share the habit of a darting flight, 'skipping'from flower to flower, rather than flutter­

ing or gliding. Some of the skippers tend tohold their wings angled at about 45' when

sunbathing, and the Dingy Skipper wraps itswings around the body when roosting.Skippers are generally the most moth-likeof the butterflies.

Grizzled Skipperl'yrglls maluae

A small butterfly; wingspan 25-28mm. The

upper surfaces of the wings are attractivelychequered white and dark brown, and the

fringes are barred with brown. The under­sides are similar but duller. A distinctive

species in Britain, but there are increasing

numbers of similar species further south.Habitat In sheltered flowery sites, such

as woodland clearings. The food-plantsinclude Wild Strawberry, cinquefoils and

other members of the rose family.Status and distribution Only in thesouth of the UK, where it is local; wide­

spread but local on the Continent.

Season 5-6 in UK, 5-B in Europe.

* Large Grizzled Skipperl'yrglls alueus

Similar in general appearance to Grizzled

Skipper, but distinctly larger (wingspan upto 33mm), and with much less white on the

upper surfaces of the hindwings; the under­sides of the hindwings have larger white

patches, and a greenish tinge.Habitat Rough flowery grassland, mainlyin hilly areas.

Status and distribution Widespread onthe Continent generally, though absentfrom much of the Low Countries.Season 5-9.

148 LEPIDOPTERA

Dingy SkipperErY11lzis/ages

Lulworth SkipperTiJ)'lIlclicliS acteeJil

One of the 'golden skippers' (as are all the

following species) which rest with their

wings at 4So. This is both the smallest

(wingspan about 26mm) and the darkest of

the group, and the females have a gold cir­cle on the forewings (upper side). The

undersides of the antennae tips are cream­coloured.

Habitat Rough g,-assland. where TorGrass or b.-omes occur.

Status and distribution Very,-estricwdin UK. on the Dorset and Devon coasts.

Widespread on the Continent f.-om NGermany southwards, rare in the north.Season 6-9.

Small SkipperThYJJ]elinlS sylzl('s/ris

A small golden-brown butterfly, with few

positive distinguishing features. Brighter

than Lulworth (above) and lacking thegolden circles; smaller and less boldlymarked than Large Skipper (see below).

Essex Skipper can only be satisfactorily sep­

arated by looking at the undersides of theantennae: black in Essex, orange in Small.

Habitat Many kinds of rough grassyplaces with flowers. Food-plants include

various coarse grasses.Status and distribution Common in S

Britain, absent from Scotland; widespreadon the Continent.Season 5-8.

Essex SkipperTiJ)'lIle/iCl/s Ii"e()/a

Resembles Small Skipper very closely. It canonly be reliably distinguished by the black

undersides to the antennae, though withexperience the slightly paler colour and the

slightly shorter sex brand on the male's

forewing, which runs roughly parallel to the

wing margin (angled slightly towards it in

the Small Skipper) can be used.

150 LEPIDOPTERA

Habitat Found in rough grassy places,

including fens and the upper parts of salt­marshes.

Status and distribution Locally com­

mon in south-eastern parts of Britain;absent elsewhere. Widespread throughoutN Europe.Season 5-8.

Silver-spotted SkipperJ /cs/)(Tid ("()1n1Jhl

An attractive skipper; wingspan 30--3Smm.Its most distinctive feature is the under­

sides of the wings, which are greenish­

brown marked with conspicuous white

spots, brighter in females. The upper sur­

faces are similar but less boldly marked,

with more orange.Habitat Chalk grassland and similar

places with short grass and ba,-e soil. Food­plants include fescues and other fine

grasses.Status and distribution Rare and

declining in the UK, confined to S England.

Widespread and locally frequent on theContinent.

Season 6-9 in Europe, 8--9 in UK.

Large Skipper()ciJ/()des uC/IiIIIIS

Rather similar to Small Skipper, but larger

(to 36mm), and with upper surfaces of

wings distinctly marked with squarish

orange patches towards the edges, sepa­rated by dark veins. The undersides are

similar but less boldly marked, though dis­

tinct from the plain undersides of Small,Essex and Lulworth.

Habitat Grassy, flowery places of allkinds. Food-plants include Cocksfoot and

other coarse grasses.

Status and distribution Increasingly

common southwards in England andWales; widespread and common on theContinent.Season 6-9.
