A BIG Diversion.

The Elephant Hawk Moth caterpillar is probably best seen in the month of August.The adult moth is an elegant pink and olive in colour and is a strong and fast flyer.Strictly speaking the caterpillar should be called a larva as it is the offspring of a moth rather than a butterfly.It is a big larva too and the one I spotted today was at least 4cms in length.

If you have fuchsia plants these will be where they are most likely seen as it munches its way through the foliage.However my Hawk moth larva was found on a pond plant right in the middle of my garden pond.The larva gives its name to the species due to the long trunk like nose,although when the larva senses danger it withdraws the 'trunk' creating a more bulbous head shape.

Back on Bonchurch Down.

With the dry and very warm weather continuing a second generation of Adonis Blue is now on Bonchurch Down at Ventnor.Yesterdays sightings on the Down included Chalk-hill Blue,Common Blue, and Brown Argus,along with one or two Marbled White, good numbers of Meadow Brown,Gatekeeper,and the odd Red Admiral.

As Beautiful as a Butterfly.

The Jersey Tiger Moth is certainly a colourful moth and today this one was seen in my garden on the Phlox blooms.I have been fortunate enough to see three in the garden over the last week.

Graylings Back on Bleak Down.

I hoped that the Graylings were out  on Bleak Down by now and made the walk to their usual site on the Down.The area is one of the few remaining stretches of heathland on the Island and with the heather now in flower it makes a colourful sight.After some time of searching I at last found a Grayling. Obviously I was somewhat early to see the colony, so hopefully in another week numbers will have substantially increased.
2017 update. A visit to this site today the 5th August discovered no Graylings. The area of past activity has now been overgrown with grasses and although flowering heather still remains in places, there is no bare open ground.  

Summertime.

A very warm and sunny morning at Walters Copse today and it was not long before I came across a pristine Painted Lady butterfly.Not too far down the path and a Dark Green Fritillary was also feeding on the giant thistles.This fritillary can be found in our woodland as well as on our chalk downland.

Now good to see reasonable numbers of Marbled White,Meadow Brown,and Ringlet in the copse.Not many Silver-washed Fritillaries though and no sign of any Valezina as yet.The normal  females however are in evidence seeking out egg laying sites at the base of oak trees.

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.
