Spring in Full Swing

Now that the first Large Red Damselfly has emerged from my garden pond it seems that summer is on the way.

Orange Tips,Holly Blues,and whites are now a regular visitors to the garden as well as a variety of bumblebees and other insects.

With the sunny warm weather still with us today another spring time species made an appearance at Whiteways Quarry.The first Grizzled Skipper was seen flitting around in the sun together with the several Green Hairstreaks already there.It should not be long before a Dingy Skipper is out and should the temperature rise over 20C the first Small Blue.

More Spring Butterflies

A further visit to Whiteways Quarry this morning recorded four Green Hairstreaks.No other species seen at the moment.Then on to Walters Copse,Newtown,and a first sighting of a Green-veined White.Also several Speckled Wood,Peacock,Comma,and three Orange Tip,one of which was a female.

Green in the Sun.

Today began with a wonderful sunny morning and an early visit to the Whiteways Quarry. where I came across a Green Hairstreak yesterday.This time the lone Green was happy to sun itself on the flowering plants at the base of the chalk down.

And a First Green Hairstreak.

Not too far from me is a site renowned for several species of spring butterfly and today under partly cloudy skies I saw a first Green Hairstreak. It was not too active as no doubt it had very recently emerged and preferred to stay down in the grass due to the weather conditions.

A First Orange Tip.

In the last several days Holly Blue,Speckled Wood ,and the Small White have visited my garden.However a sure sign of spring happened today when a first Orange Tip appeared.A male busily flew around the garden looking for something it may fancy but apart from the bluebells there did not seem to be any flowers that took its interest.Definitely something for me to take note of for next year.

A Special Resident.

In the UK the Glanville Fritillary is only resident on the Isle of Wight.Therefore that makes it a very special butterfly to us here on the Island.Normally at this time the Glanville larvae are approaching full size after spending the winter months secure in a web deep in the long grass on the cliff top or the cliff slopes.The coastal cliffs along our south western shore are ideal habitat and the webs are on or very near to its foodplant, Ribwort Plantain

Now is the time for the larvae to disperse and find a safe place to pupate.The chrysalis stage lasts for about three weeks and the adult is on the wing during May and June.

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.
