Pierids in Sussex

 The white and yellow butterflies in Britain all belong to the Pieridae family. 

Of those species that occur in Sussex, most are common and widespread and found in a range of habitats.

 However, one is a rare resident, only to be found in a few small colonies in the north-west of the county.

Wood White (Leptidea sinapis)

This species is our rarest Pierid in the county and only occurs in a few areas in north-west Sussex.

Clouded Yellow (Colias croceus)

This species is a migrant to Britain, occurring annually in varying numbers. Some years it can arrive in huge numbers and produce summer and autumn broods. In other years it can be a rare sight.

(female, form helice)

This pale form accounts for about 10% of the female population.

Brimstone (Gonepteryx rhamni)

The Brimstone hibernates as an adult butterfly and is one of our first species to be seen on the wing during late winter and early spring sunshine.

Large White (Pieris brassicae)

This is a common and widespread species. Together with the next species, it can cause serious damage to garden cabbage crops.

Small White (Pieris rapae)

This common and widespread butterfly is also a cabbage crop pest.

Green-veined White (Pieris napi)

This cousin of the previous two species is certainly not a garden pest. It is more akin to the next species in its choice of habitat, preferring to wander along field margins, verges and woodland edges, looking for foodplants such as garlic mustard and lady's smock.

Orange-tip (Anthocharis cardamines)

This pretty little butterfly is a true harbinger of spring, emerging from its overwintering pupa from late March to late May.
