Another Spring Blue.

The Adonis Blue is the latest 'blue' to appear this year and without doubt the most magnificent.The male is splendid with its vivid turquoise wing colour and is in fact our rarest blue in the UK.

Today on Bonchurch Down only three males were seen but hopefully many more will grace our chalk downland in the coming weeks.In addition,there was a first of the year sighting of Small Heath and Wall Brown and a good number of Common Blue,Brown Argus,and Dingy Skipper.Several Small Copper and 'Whites' were evident too.

Bonchurch Down Delivers a Bevy of Butterflies.

The south facing slopes of Bonchurch Down look out over the English Channel.The Down is well known for the Adonis Blue Butterfly as well as a selection of other butterfly species.The Adonis is not yet on the wing but a walk along the slopes this morning produced a bevy of butterflies.

It was the first sighting this year of Common Blue,Brown Argus,Dingy Skipper,and a Clouded Yellow.The latter is known to breed just a short distance away around Wheelers Bay where adults are observed regularly in April.More than likely the individual seen today was a migrant as we have been  enjoying a very warm southerly wind recently.

First Adonis Blue & Glanville Count Rises.

With Adonis Blue already reported from several mainland locations,I decided to try my luck today on Bonchurch Down.The numbers of Adonis have decreased in recent years due to less than ideal land management on the Down and the fall in the rabbit population.The Adonis require short downland grass to be successful and the lack of grazers such as the rabbit has allowed the grass to grow long.A check of the male Common Blue butterflies encountered today led to my first record of the year of a Adonis Blue.These two species are very similar,but close inspection will leave no doubt if it is an Adonis. The spectacular and striking sky blue of the male Adonis is unmistakeable.

Not too far away is the premier site for the Glanville Fritillary and since the first appearance of this special butterfly four days ago numbers have steadily increased.Todays count amounted to eight pristine fritillaries all resplendent with their orange and brown chequered wings and a white border.The underside has a pattern of cream and orange bands with black marks.

Late Summer Colours.

Not too far from Wheelers Bay is Bonchurch Down, well known for its downland butterflies.This south facing Down has a good population of Adonis Blues and now the second brood of the year is on the wing.Many of the stunningly coloured males are now showing signs of wear but they are still strikingly impressive.

Among other butterflies seen on the Down yesterday are Common Blue,Brown Argus,Meadow Brown, and I am very glad to say,Small Copper.These quarrelsome and restless little butterflies have suffered a decline recently,perhaps due to poor summer weather,so it is good to encounter them now.

 

All Now in Top Gear.

That prolonged spell of cold and windy weather has seemingly passed and we are now enjoying very warm sunshine and light breezes.Needless to say that has produced great activity in the butterfly world.

A visit to Bonchurch this morning was rewarded with my first sighting of our Glanville Fritillaries,just two were spotted but numbers are expected to increase quickly in the sunshine over the next few days.Judging by the high count of caterpillars and webs earlier in the year it could well be a bumper year. Another new species for the season was the Common Blue,seen at the same location.This was followed by a walk on Bonchurch Down and after some searching we succeeded in seeing four Common Blue,a Small Copper,one Small Heath,and two Dingy Skippers.The latter two species were also first sightings of 2016.

The Holly Blue pictured below had just emerged and when the wings have developed,she would expect  to take to the air. 

 

Adonis on Bonchurch Down.

With  the prospect of several days of settled sunny weather there was no better time to take a walk on Bonchurch Down  to see the Adonis Blue.It seems numbers are less than other years so counts are in tens rather than hundreds. Nevertheless it was a joy to see this most brilliant butterfly on the wing feeding on downland flowers and flying strongly on the Downs' slopes.That is,of course the males as they display those sky blue wings.The females are altogether different with brown wings,although sometimes they show variable amounts of blue.

Sky Blue Adonis Blue.

A long overdue visit to Wheelers Bay at Bonchurch yesterday discovered  some late summer colour behind the revetment at the base of the cliffs.Several species of butterfly were feeding on the ample drifts of Red Valerian and other flowering plants. Among them, a single male Adonis Blue splendid in striking sky blue. August and September is the time of the Adonis Blue second emergence of the season on our downland,so this individual is some distance away from his usual habitat on Bonchurch Down.

Visiting My Favourite Island Sites.

The prospect of a warm and sunny spring day encouraged me to visit a few of my favourite locations on the Island.First stop the National Trust owned Whiteways Quarry now a Viewpoint Carpark, commanding majestic views over our south-western coast.Here at the old quarry, a fantastic assortment of spring butterflies are protected by the shelter of Afton Down and today there was another new species to see.The Small Blue is our smallest butterfly and lives in very compact colonies.The males are usually the first to emerge and can be recognized by the dusting of blue scales on their upper wings.At least three were present today.Also here were a pair of mating Wall Brown butterflies.This species has declined in the UK over the years but can still be seen in good numbers on the Isle of Wight.

Leaving the carpark for a drive south along the coast to Wheelers Bay at Bonchurch, for another look at our Glanville Fritillaries which are the first in the country to appear at this location.Although at times the cloud shaded the sun today I counted four individuals.Many more will emerge along our southern coast during May.

Finally a steep walk up to Bonchurch Down that overlooks the village of Bonchuch and  the town of Ventnor.This south facing Down is one of the prime places on the Island for the spectacular Adonis Blue butterfly and a walk along the Downs' steep sides produced a first male Adonis.

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.

Back on Bonchurch Down.

A return visit to Bonchurch Down today in the anticipation of seeing the first Adonis Blue on the year.I was not disappointed as after finding several Common Blue butterflies which are similar to the Adonis from a distance, I saw a male Adonis. If last years numbers are repeated it will not be long before the Down is awash with the spectacular blue of this butterfly.

The blue of the Common Blue although less intense is no less attractive.

On Bonchurch Down

Owned and managed by the National Trust,Bonchurch Down rises steeply over Bonchurch village and the town of Ventnor.This south facing hillside is home to a good population of the Adonis Blue butterfly as well as several other species.Yesterday on a very warm and sunny afternoon I made my first visit of the season to the Down and was rewarded with a sighting of four Small Copper,a Brown Argus,a Small Heath,a Green Hairstreak,also a Wall Brown together with a Dingy Skipper and three male Orange Tip.

Then a short trip down to Wheelers Bay in Bonchurch in the hope of seeing a Glanville Fritillary.I was not lucky enough to see one but I have it on good authority that a Glanville was spotted today at the Bay.
