Chalk-hill Blues Now On Show.

Several Chalk-hill Blues on West High Down today blown along on a very stiff wind.Hopefully in a few days numbers will steadily increase and reach last years staggering totals.More Dark Green Fritillaries now on the wing. all nectaring on the abundant flowering plants on our Downs.

Thymelicus sylvestris or Thymelicus lineola.

 

Today at Wheelers Bay both Essex and Small Skippers were to be seen sharing the same habitat at the foot of the cliffs.

These two species are very similar and apparently there are several minor differences which will enable the observer to tell one from the other.I prefer to take a close look at the antennae,as the Essex has a distinctive black tip on both whereas the Small Skipper has mainly dull brown-orange tips.On the Essex the black extends to underside of the antenna tips.

This difference can be seen (I hope) in the following photos taken today of the butterflies at the Bay.The first two examples are of an Essex and the last two a Small Skipper

Still Waiting.

A hike up to West High Down this morning in the hope of seeing my first Chalk-hill Blue of the year.I was to be disappointed as despite a good search it did not seem that any had emerged,at least on this part of the down.

I did see a new species for this season though,a male Gatekeeper sheltering low down in the gorse away from the stiff breeze.Many more Marbled Whites now and one or two of the Dark Green Fritillaries are starting to look somewhat faded.

Still Around.

A surprise sighting yesterday at Shepherds Chine on the Islands' south west coast was a late Glanville Fritillary. The first sighting was back on 29th April and normally one would not expect to see it in July.

The Dark Greens.

Quite a common butterfly on Isle of Wight downland is the Dark Green Fritillary.It is also found in our woodlands too.One of the areas I like to visit in order to see this handsome butterfly is West High Down situated between the Needles and Tennyson Down.Perhaps its favourite nectar flower is the Giant Thistle and one can almost be guaranteed a sighting of the butterfly amidst a drift of these plants I was not disappointed today as despite a stiff wind and mainly cloudy conditions I managed to see four,all feeding at one time or another on the thistle.

A Walk in Walters.

This National Trust copse  at Newtown village boasts a good selection of  flora and fauna and I took an extended wander through it today.

White Admiral numbers continue to grow with the Silver-washed Fritillary numbering just three at the moment with two males and a female.Ringlets are very numerous,as are Meadow Browns but Marbled Whites are scarce at present.A few more Small Skippers are out now together with a couple of Commas.With the weather continuing settled,in the main,butterfly numbers and species are set to increase.

Small But New.

After seeing a first of the season Small Skipper last week,today while walking along the cliff top at Whale Chine I came across another male in the long grass close to the cliff edge.This stretch of coastline has an allocated strip of land several metres in depth from the edge of the cliff which is designated as a Site of Special Scientific Interest (SSSI)

Details of which are;
 On the south west coast of the Island, cliff top arable fields border parts of the Compton Chine
to Steephill Cove SSSI. In these locations a buffer zone has been established by Natural England
between the arable field and the cliff top. Management of this has been undertaken through a

Wildlife Enhancement Scheme (WES) agreement between Natural England and the landowners.

These agreements are now mostly about 10 years old and are currently being re-negotiated
through the Environmental Stewardship Scheme (ESS) as Higher Level Stewardship (HLS)

agreements.

Management of the buffer under WES agreements required:-

• No cultivation within 20m of cliff or chine edge
• No application of fertilisers, herbicide or pesticide within 20m of cliff or chine edge
• Scrub management
• Control of ‘weed’ species is required by WES/HLS – to include ragwort, thistle, dock and

nettle. This appears to be achieved through annual topping in late summer.

Summer Hots Up.

We are enjoying a settled period of hot, early summer weather and butterflies are certainly responding to the conditions by emerging a little head of time than one would expect.In Walters Copse today I saw my first Small Skipper of the year and the first Marbled Whites are now flying with the ever increasing numbers of Meadow Browns and Ringlets.With the White Admirals now in the copse they have been joined by Silver-washed Fritillaries and with their strong flight they seem to rush from one nectar source to the other.
Of the several types of orchid now to be seen in our woods and copse is the beautiful Bee Orchid as discovered today in Walters Copse.

Back to Wheelers.

I do not think that I have wandered along the revetment at Wheelers Bay since first seeing the Glanvilles at the end of April.So on a hot,sunny morning I made a point of visiting to see what butterflies were to be seen.As the Glanvilles have been on the wing here for over six weeks I was not surprised to come across several well worn butterflies,although one or two were in excellent condition.Apart from the numerous Common Blues,I also saw Small Blue,Painted Lady,and Marbled White.Still very much worth a trip as one can never tell what other continental species will arrive.

Wight Elegance.

A quick visit to Walters Copse today in the hope of seeing some new species for this year.It was a very sunny late morning with a light breeze.I soon came upon numerous Meadow Brown butterflies together with some Speckled Wood.However a butterfly flitting around the tree tops at about thirty feet up took my eye and it was my first White Admiral of the season.Eventually with that very elegant flight,it made its way down  to feed on the ample crop of bramble flowers that are dotted along the ride edges.This individual was quickly joined by another and despite a few encounters with the resident Speckled Woods they remained on the bramble for a time.

A little later I had two further White Admiral sightings in the copse plus a well traveled Painted Lady.
