Satyrids in Sussex

 The Satyrinae are a sub-family within the Nyphalidae family. Of those that occur in Sussex, one is a rarity but the others are common and widespread within the county. They all use various grasses as a food-plant on which to lay or scatter their eggs and the commoner species can be found in a range of habitats.

The males and females are similarly marked but there are sufficient differences between them to tell them apart, particularly where males of some species show a notable sex-brand in the centre of the forewings.

Speckled Wood (Pararge aegeria)

This is a species of dappled woodland edges, where males battle each other for territories.

Wall (Lasiommata megera)

In Sussex, megera is predominantly a downland species but also occurs on coastal flats and along woodland rides.

Marbled White (Melanargia galathea)

This is a very common downland species but small colonies can also be found in wealden glades and field edges.

(males)

Grayling (Hipparchia semele)

This is the rarest of our Satyrids in Sussex. I am not very up-to-date with its status in West Sussex but in East Sussex, semele is more-or-less restricted to one south facing hillside on the South Downs.

(female)

(mating)

The Grayling only shows its upperwing surface during courtship or, as in the following image, when a mating male is fending off another male.

Gatekeeper (Pyronia tithonus)

This is a common and widespread species in Sussex.

(male)

(male) (ab. obscurior)

(female)

(female) (ab. anticrasipuncta)

Meadow Brown (Maniola jurtina)

This is a common and widespread species in Sussex.

(male)

(male) (ab. pallidus)

Not to be confused with age related bleaching that often occurs in this species.

(female)

(mating)

Small Heath (Coenonympha pamphilus)

This common and widespread butterfly rarely displays its upperwings.

(mating)

Ringlet (Aphantopus hyperantus)

This is a common and widespread butterfly of  damp woodland rides and glades.

Early Autumn on Pevensey Levels

Since the beginning of September, the maize crop has been harvested for winter feed, the meadows have been mown and the hedgerows and tracksides have been cut back. The Environment Agency has already started raking the Floating Pennywort (an invasive species) from the water ditches and Pevensey Levels have a rather end of season feel about them.  

However, there is still plenty of  wildlife activity to be found.

Small Copper (Lycaena phlaeas) (3rd brood female)

Red Admiral (Vanessa atalanta)

Brown Argus (Aricia agestis) (2nd brood female)

Wall (Lasiommata megera) (3rd brood)

(male)

(female)

Comma (Polygonia c-album)

Peacock (Aglais io) (2nd brood)

The Peacock has predominantly been a single brooded species in Britain but during the last decade or more, a second brood has become an increasingly regular occurrence and on Pevensey Levels, there has been a significant second brood emergence this year.

(the larva had successfully pupated on 1st September 2025)

(the pupa on 5th September 2025)

A few days later I revisited the pupa to find that it had been dislodged during windy weather. It was suspended by just a very fine thread and spinning in the wind and I reluctantly brought it home for safe keeping.

(by 15th September 2025, the wing markings were visible through the pupal membrane)

(on the 16th September 2025, the imago has emerged)

(the imago was safely returned near to where it pupated)

Migrant Hawker (Aeshna mixta) (male)

Golden-ringed Dragonfly (Cordulegaster boltonii) (male)

Cuckoo (Cuculus canorus) (juvenile)

Reed Warbler (Acrocephalus scirpaceus) (nest)
