A Hot Afternoon in Firestone Copse.

On a hot afternoon the partial shade of the woodland glades in Firestone Copse was welcome today.Almost immediately along the first track,I was passed by a string of Silver-washed Fritillaries and one of my encounters here was with a female Silver-washed looking for a shady spot to lay her eggs.They tend to choose the base of a tree trunk and this one fluttered into the dark to lay on several trees.This was mixed with feeding on convenient bramble flowers and resting in the dappled sunlight

White Admirals were also plentiful and found particularly on bramble flowers and any damp spot on the ground where they could obtain moisture.Meadows Browns and Ringlets were very numerous.

The Silver-washed Fritillary in Walters Copse.

At Walters Copse,Newtown,the Silver-washed Fritillary is now enjoying the hot summer weather and can be seen all over the wood.Together with the White Admiral they visit bramble flowers along the dappled woodland rides.The Silver-washed is a powerful flier and can disappear as quickly as it appears heading off at great speed through the trees.However sometimes they can be captured,as in the following photos,firstly a courting couple on bramble and secondly a mating pair in the tree tops.

The Elegant White Admiral

The elegant White Admiral is now on the wing in our woodlands.At Walters Copse,Newtown,today as the summer sun shone through the trees and along the rides this lovely butterfly could be seen gliding in and out of shade.Accompanying the White Admiral now is the Silver-washed Fritillary,another woodland butterfly.

Woodland Butterflies

The weather this week has continued to be wet.Woodland butterflies will no doubt suffer from this dismal time and species such as the White Admiral and Silver-washed Fritillary will have a disappointing season.

A visit today to Walters Copse at Newtown was a mixed one of sunshine and showers.Meadow Browns were numerous as this butterfly is a common sight.Just a single Marbled White was to be seen together with a Red Admiral.The White Admiral and Silver-washed Fritillary were also flying.

The Adonis Blue

The Large Tortoiseshell

It seems the general view on the status of the Large Tortoiseshell in Britain is that it is now extinct as a breeding butterfly.
It is a butterfly of woodland edges and hedgerows that abound in willows,elms,and poplars.These trees are used by the adult to lay its eggs and this single brood appears in July and August.The emerging butterfly then hibernates over the winter in log piles and hollow trees until the next spring.
On the Isle of Wight sightings are more often than not made from early March to April.Have these butterflies overwintered on the Island or have they come from the continent where it is common?
Any sightings made in July/August pose the same question.Another explanation could be that captive-bred releases are responsible.Only the discovery of eggs and caterpillars will probably answer these questions.

I can now report that evidence has been found of breeding just along the coast at Portland in Dorset (June 2020) and again at the same location in the summer of 2021.

The Glanville Fritillary

This elegant butterfly is mainly confined to the crumbling undercliffs and chalk downs of the Isle of Wight.It is also found on the Channel Islands and at one or two isolated colonies on the British mainland.In Britain the Glanville Fritillary is at the extreme north-western edge of its range.On the continent it is readily found in flowery habitats.
Around the southern shores of the Isle of Wight the cliffs constantly erode causing them to slip away and provide perfect conditions for new growths of the butterflies laval host plant,Ribwort Plantain.
The eggs are laid to the underside of the leaves of this plant and normally hatch after about three weeks.The resulting caterpillars live together in communal webs spun over the plantain.In the autumn they hibernate and recommence feeding in the spring,eventually dispersing to prepare for pupation.
The adult butterfly is on the wing from May to the end of June with the female being larger than the male.They will feed on,amongst other things, Birds-foot Trefoil and Thrift.

The Wall Brown

On the Isle of Wight in particular,the Wall Brown is a butterfly of field edges,coastal cliffs and dunes,and rabbit-grazed downland.
The male is territorial and spends much of the time patrolling and basking on the ground.
The female,which lacks the males conspicuous dark sex brand across the forewings,is larger.The undersides of both sexes are beautifully cryptic when at rest.
The Wall Brown generally produces two broods a year,the first from late April until late June and the second from mid-July to mid-September.
