Butterflies Respond to the Warm Spring Weather.

The cold weather brought on by a persistent and brisk easterly wind last week has now gone and we are now enjoying sunny and warm days with temperatures in excess of 20 degrees Celsius.The butterflies are beginning to respond with regular sightings of Orange Tip and a big increase in Green Hairstreak at a favourite site at the base of Afton Down in the West Wight.A lunchtime visit to Whiteways today produced a count of six to eight individuals.Unfortunately no other new species were as yet on display.

Spring is Well Under Way.

Following yesterdays sighting of a Green Hairstreak at Whiteways,I was hopeful that another new springtime butterfly may be on display today.It had again developed into a warm and sunny afternoon after a chilly start and it was not long before I came across a Grizzled Skipper enjoying the sun.It seems that with the promise of dry and bright weather for the next few days spring is now well under way.

Green Hairstreak First to Appear.

A cold morning preceded a warm and sunny afternoon, and it was the Green Hairstreak that appeared as the first resident new emergent today at Whiteways (Afton Down Chalkpit).Their numbers will steadily increase over the next week or two and they will be joined by a host of other spring species.

Old and New.

The last several days have continued to be cold for this time of the year.However new emergent and old overwintering butterflies are appearing without delay.A first visit this season on Monday last, to a favourite butterfly spot at Whiteways Quarry produced a very active Small White.Today at the same location under showery skies, there was a Small Tortoiseshell enjoying the sunny spells.If the weather warms up soon I am certain that the first new butterflies will be seen here at Whiteways.

The First Speckled Wood of the Year.

A walk along the wooded banks of Shalfleet Stream today was rewarded with a sighting of the first Speckled Wood of the year.Alas it was only a brief glimpse as this new emergent quickly flew over the stream into the woodland.

Just the Usual Suspects.

With the spring weather warming up over the last few days and set to continue,I was very hopeful of seeing the first newly emerged butterflies of the year today.

Speckled Wood and Orange Tip have already been sighted on the Isle of Wight and an afternoon walk through Bouldnor Forest and later Walters Copse at Newtown proved to be a disappointment as I failed to see any of these two species.Still,the usual suspects were out and about.Male Brimstone forever on the move, along with several basking Comma,a Red Admiral or two on the tracks,and good numbers of Peacock.The latter it seemed always to be found close to  Pussy Willow which is now flowering in our damp woods.

First Butterflies of the Year as the Fine Weather Continues.

The very mild weather continues and temperatures reached nearly 20 Celsius today.A first trip of the year to Walters Copse,Newtown owned by the National Trust resulted in five Comma butterflies and at least four Brimstone.The Commas were basking in their usual spots, namely sunny and sheltered rides whereas the male Brimstone flew energetically about looking for females, pausing briefly to nectar on the few primrose flowers and enjoying a sunny location.

Mild Temperatures Bring Out the Glanvilles.

The mild temperatures of the last week have enticed  the Glanville Fritillary larvae out of their winter hibernacula to sun themselves on the south facing slopes of our Island cliffs.

The webs seen today at Shepherds Chine revealed many caterpillars out and about enjoying the warm sunshine.They are no more than one centimetre in length at present and into their fifth instar.

More Late Summer Butterflies.

At this time in late summer, the Clouded Yellow can sometimes be seen dashing around our fields and open woods.Most originate from mainland Europe,however I am sure that here on the south coast we have our own 'home grown' individuals.

In Bouldnor Forest near Yarmouth there is an open area in the woodland.Here a group of almost dried out scrape ponds are surrounded by low scrub and gorse bushes.Yellow Fleabane is prolific and a favourite for nectaring butterflies and today under sunny skies  there were no shortage of species.As well as the Clouded Yellow, Common Blue,Small Copper,Wall Brown,Red Admiral,and a Painted Lady were on show.

Late Summer Butterflies on the Landslip.

Today on the landslip beneath the coastal cliffs along the south west shore of the Isle of Wight there was a good selection of late summer butterflies.This unique area is well known for the Glanville Fritillary butterfly during May and June.A strong onshore wind blew today but in any sheltered spot,especially where yellow fleabane is flowering the butterflies congregated.Many seemed to be a excellent condition with Common Blue particularly striking.Surprisingly the Wall Brown proved to be the most numerous,as these coastal cliffs are a favourite for this species.Other butterflies on the wing were Peacock,Small Copper,Small Heath,and two flyby Clouded Yellow.

Adonis Blue & More on Mottistone Down.

Mottistone Down is one of several National Trust areas on the Isle of Wight's south west coast that supports a range of chalkland butterflies.The scenic walk from the village of Mottistone gives panoramic views south along the Islands coastline and north to Freshwater Bay  and Tennyson Down.As I made my way up to the top of the Down today I passed the Long Stone a well known  ancient monument.Sightings on the Down were few due to the brisk wind although in any sheltered spots butterfly numbers were good with Adonis Blue,Chalk-hill Blue,and that master of camouflage,the Grayling on show.There were also several Wall Brown to be seen too.

High Summer Butterflies.

The scrub around the woodland ponds in Bouldnor Forest is now covered in drifts of Common Fleabane Pulicaria dysenterica. These yellow flowers are a magnet for butterflies and a stroll through this impressive and colourful floral display discovered several summer species.In addition to the common 'browns' there were a great number of Common Blue,together with a Painted Lady and a Clouded Yellow.Unfortunately the latter was quickly shooed away by the Blues.

Some of the ponds here are almost dry and it seems that they are attracting Wall Brown butterflies, as a few were observed landing on the parched earth maybe for salts.The scrub too was of interest to female Wall Browns,perhaps as a place to lay their eggs.
Among the crowd of blues near to an almost dried-up pond was a male Chalk-hill Blue.It too attracted to the pool for the salts or just a wanderer perhaps.
