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.

First Speckled Wood.

Today started very foggy and it was not until after noon that the sun managed to shine through.When it did however it turned into a warm sunny day with no breeze.

In Walters Copse I came across my first Speckled Wood of the year.Three in fact, together with the usual good number of Comma,Peacock,and Brimstone.The main quarry was not to be seen and one wonders if the Large Tortoiseshell will not make an appearance in the copse this year.

Spring Back on Track.

A sunny day at Walters Copse and any sheltered spot was sure to turn up a Peacock butterfly.Signs of spring were confirmed by more general activity, as hoverflies and beeflies seemed to be everywhere as well as bumblebees.Some Common Carder,Tree,Buff-tailed and a Red-tailed bumblebees were seen.

No sign however of any Brimstone or newly emerged butterflies although Comma and Red Admirals came out to bask in the sun and nectar on the sallow blooms.

Butterfly Sightings Plummet.

Scant few butterflies today at Walters Copse.In fact I could count on one hand the number of individuals I saw there.That may be explained by the weather which has changed from the sunny,warm,and settled spell last week,to cooler,windy,and mainly cloudy..When the sun did shine today it was pleasant but there was a chilly brisk breeze.Still I did see three species,the Peacock,Comma,and a Small Tortoiseshell so let us hope that the weather improves again soon.

Temperatures & Butterflies Takeoff.

Although there was thick fog this morning ,the day developed into what must be the hottest of the year.Not only did the temperature take off but also the butterflies, with lots of activity in Walters Copse.

The prime target was yet again the Large Tortoiseshell,but apart from a couple of possible flight sightings this week in the copse, it is proving to be elusive,as always.There is no shortage however of other species like the Comma,Peacock,Brimstone,and the Small Tortoiseshell.

The first Bee-flies have now started to appear.This one is the common Dark-edged Bee-fly.

Taking to the Shade.

A lovely warm afternoon at Walters Copse,Newtown today,no chilly breeze and the prospect of warmer weather next week.The butterflies responded with several Brimstone on the wing together with three Comma,a Red Admiral,and a Peacock,in fact the usual suspects at this time of year.Some of the Brimstone were making for the shade of an ivy leaf.

Spring Colours

Today continued on the mild side and as temperatures are due to rise in the next week,spring it seems is here.With the sunshine has come a flurry of butterfly reports with many now out of hibernation.My garden was no exception with two peacock and a very intensely coloured small tortoiseshell.Variation is fairly frequent in the latter which usually consists of differences in the shade of the ground colour,as in this case.

Others on the Wing.

Butterflies are not the only insects now appearing.With the mild springlike weather continuing and several early plants flowering in the gardens the Buff-tailed Bumblebee is making the most of it all.

This bumblebee is the most likely of the bee family to be seen at this time and even a few weeks ago I saw one visiting the hellebore flowers.

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.
