Back to the Landslip.

The area of Landslip close to Compton Chine and just a stone's throw from Freahwater Bay, provided my first visit of the season to this unique habitat in the hope of seeing an early Glanville Fritillary.Unfortunately. just a few day's too early it seems as the only species recorded were Green Hairstreak,several Dingy and Grizzled Skipper,a Wall Brown,a Small Copper,and a first sighting this year of a Small Heath. Weather conditions were mild with little wind although mainly cloudy but bright and thrift is now startting to flower on the cliffs.

Returning to Whiteways NT carpark situated overlooking Compton Chine and where I started my visit today,I came across a pristine Brown Argus.Another first of the season sighting.

A Promise of Spring on our Coastal Cliffs.

A walk along a very breezy clifftop today allowed me to access a section of the landslip close to Compton Bay. The coastline all along the south west of the Isle of Wight suffers from coastal slump as the cliffs periodically slide towards the sea. In fact evidence of recent slippages are for all to see along the path taken today.

It seems that only Small Copper butterflies were on show in this area of landslip this afternoon as I recorded at least six individuals. They were particularly fond of the odd clump of thrift, as just a few early flowers were to be seen dotted around. All too soon the cliffs will be covered in their bright pink blooms which are a favourite of the Glanville Fritillary which is due to make an imminent appearance.

Back on the Landslip & Back to Nature.

The month of May is of course the time for the Glanville Fritillary here on the Isle of Wight.Now that restrictions have been relaxed, a short car ride to Afton Down Chalkpit and a walk down to the National Trust clifftop at Compton Chine provided access to the landslip.Descending the impressive wooden steps onto the landslip I was treated to a view along the coast towards Compton Bay.

Today the Glanville Fritillary was in evidence on the clifftop and below, although due to the brisk onshore wind they were very active and jittery.Nevertheless,find a sheltered spot and many butterflies could be approached as they rested in the sunshine or nectared on the flowering thrift. Among the other species on show were Common Blue,Dingy Skipper,Small Heath,Small Blue and Brown Argus.

Glanvilles Take Over the Slopes.

It is now three weeks since the first adult Glanville Fritillary was reported on the the Isle of Wight.Today on the landslip close to Compton Chine the Glanvilles were out in force despite the seafog rolling in and cooling down the temperatures.In cloudy weather the butterflies tend to snuggle down in the long grass but there were still plenty to see nectaring on the thrift and ribwort plantain.It certainly looks like another good year for this butterfly and encouraging are sightings made in the east of the Island.

Glanvilles Showing Well.

At this time of year the cliffs on the Isle of Wight are carpeted in Thrift and these drifts of bright pink attract insects, in particular the butterflies.The number of Glanville Fritillaries are now on the increase and today I saw many on the landslip.The peak of their season has yet to arrive and hopefully there will be many more on the wing during the next few weeks.

Painted Lady

The Painted Lady is well known for being a migatory butterfly.Here on the Isle of Wight it can first be seen in May,as in the photo feeding on Thrift,on the coastal clifftops.Into September and October it can still be found in near perfect condition.Unfortunately the Painted Lady does not seem to be able to survive our winters so in the spring new butterflies will spread to Britain from southern Europe

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.
