Small Blue Braves the Cold.

I was amazed to see a Small Blue today in the company of Grizzled Skippers,Green Hairstreaks,and a Small Copper, all now at Whiteways Quarry site.My surprise is of course due to the cold and breezy weather we have had for a while as the Small Blue is fond of warmer temperatures. It is also over two weeks earlier than the first sighting of this species last year.

Seeking the Sun's Warmth.

The weather continues to remain unseasonably cool with that cold north wind.This does not encourage butterflies into much activity so the sight of a roosting Small Copper this morning at Whiteways was a bonus.By the look of its condition it seems that this buterfly has been about for a few days and is probably the same one that was spotted here a week or so ago.Once the sun appeared through the clouds the butterfly proceeded to spread its wings to get what littie warmth there is around now.

Spring Slows Down.

We have endured several days of cold weather due to persistent north to east wind resulting in few sightings of butterflies..However find a sheltered spot and some warm sunshine and they can appear.This is true of the Green Hairstreaks at Whiteways which would normally emerge before the Grizzled Skippers or very soon after the first skipper. So it was not until today that a Green Hairstreak was seen flitting around at the back of the car park,a full 11 days after the first skipper here.The weather is set to remain on the cold side for the time of year so new sightings will probably be meager.

Waiting for the New Arrivals.

A morning visit to Whiteways Quarry did not discover any new emergent butterflies today.The lone Grizzled Skipper should very soon be joined by other skippers,several Green Hairstreaks,,and butterflies including the Small Blue.

A Small White was also seen enjoying the early warmth of the sun.

First Spring Skipper.

Whiteways Quarry or Afton Down Chalkpit as it is commonly known has been mentioned in many of my previous posts.Nestled at the foot of Afton Down on the main road south out of Freshwater Bay it is a prime spot for spring butterflies.Among the many species that emerge here is the Grizzled Skipper and today the first one appeared taking time to nectar on the several clumps of Spanish Bluebells,Hyacinthoides hispanica that are scattered along the rear of this viewpoint car park

A Walk in the Wood.

it was a case of sunny intervals this morning when I visited my local copse.However when the sun did shine it was pleasantly warm and it enticed several butterflies into activity.My total count of butterflies after a couple of hours strolling along the rides were 3 Comma,3 male Brimstone,2 Peacock,and a Speckled Wood.The latter was my first sighting of this species of the new season and over a week earlier than last year.

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.
