Kithurst Meadow

 

With the Pearl-bordered in the bag I needed my second spring priority, the Duke of Burgundy. Kithurst Meadow was an all but guaranteed location and it would give me some of the other spring butterflies.

It fills you with confidence when you walk into the meadow and see Cowslips the preferred egg laying plant and Bugle a good nectaring plant growing everywhere.

The Dukes were soon found with probably a dozen flying in the sheltered part of the meadow.

There were also lots of other species flying

Common Blues, Large and Small Whites, Brimstones, Red Admirals and Peacocks were also seen but were not stopping for a photograph.

Rewell Wood

 

I have written this same blog, around the end of April, for many years now and it has always been titled Pearl-bordered Fritillary. It marks the start of the butterfly season for me and usually consists of three parts, see and photograph the Pearl-bordered, see and usually fail to photograph the Speckled Yellow moth and then, in the afternoon, go looking for the Duke of Burgundy at one of its locations on the downs.

Today that all changed. The Duke of Burgundy had come to Rewell Wood.  How it got there is open to speculation but it was definitely flying there.

Pearl-bordered Fritillary

We found the first Pearl-bordered about a quarter past nine. The sun was starting to warm the ground but there was still a cool wind blowing. Ideal conditions, the butterflies were just starting to move but were still sluggish and thus giving good views as they basked in the sun.

They could also we found basking on the dirt paths which warm up faster than the surrounding vegetation.

All very much as expected until another butterfly came into view. At a distance, the right colour, but a bit on the small size and flying a bit closer to the ground, a Duke of Burgundy. A quick record shot and a phone call to Dave, who at this point was out of sight about a quarter of a mile away and then I had to make sure I kept sight of it until he managed to get back to see it.

He made record time. It is not an unusual butterfly for us to see but this was a first for us in Rewell Wood and he wanted to record it himself. He probably also wanted to check that I had the identification right. A Duke of Burgundy and it had only just turned nine thirty, something of a record as they don't usually put in an appearance until closer to eleven.

Duke of Burgundy

Although we are used to seeing the Duke of Burgundy on open chalk downlands it was, in the past, more a butterfly of coppiced woodland. So it is perhaps not unusual to find it somewhere like Rewell Wood. We did not see any of its favoured foodplant, the Cowslip, in the area but there were plenty of  Primroses growing which are from the same family Primulaceae. 

The mystery is how they got there. I am not aware of any colonies within a reasonable migration distance of the wood. An assisted migration or perhaps they have benefited from the " Fritillaries for the Future" program?

We saw probably half a dozen Dukes allowing for multiple sightings from some of them. This is a good number for a coppiced woodland so early in the season and suggests there may be a sustainable population there.

The other encouraging aspect is that in the past the Pearl-bordered had been holding on in just one or two areas of the wood. Today we found them along rides where we had not seen them before and in widely dispersed areas of the wood.

A couple more of the early season butterflies, a Dingy Skipper and Grizzled Skipper from a recent trip to Levin Down.

I have also seen a few Green Hairstreaks, one of my early season favourites, but as yet I have not been able to get a photograph of one.

The butterfly season rolls on and next on the list is the Duke of Burgundy. A beautiful little butterfly and probably the easiest species in Britain to photograph providing you know where to find them.

The go to place around where we live is Kithurst Meadow. It is easy to get to, there are lots of Dukes there and they are easy to find. However, it gets a bit crowded and it's not much of a challenge so Dave and I decided to visit one of our old haunts Heyshott Down. A lovely location but it is further to drive, it's probably a two mile walk in, and you have to search a large area on a forty five degree slope.

The walk in is ok but we are both getting older and the forty five degree slope really takes it out on your knees. Particularly as we couldn't find any Dukes and ended up spending a couple of hours going up and down it.

It was colder than we had expected and there was a strong swirling wind but it was still a disappointment. The consolation prize was Dave spotting a micro moth during the walk out. We think it is the Green Longhorn Fairy Moth - Adela reaumurella

The next day I took the easy option and visited Kithurst. The Duke is quite a lazy butterfly, it doesn't get active until about eleven and it goes to roost at before four in the afternoon.

I missed the crowd by going mid afternoon but the number of butterflies had reduced from a reported twenty five plus to just four or five. No problem though, five was enough to keep me busy

Duke of Burgundy

Great to see the Dukes once again but I have since learnt that Heyshott is no longer a good place to look for them. There seems to be problems with the scrub clearance there and the population is in decline.

Other butterflies seen at Kithurst included Brimstone, Red Admiral, Grizzled Skipper, Dingy skipper, Orange tip, Common Blue, Whites and Brown Argos, together with a couple of moths Pyrausta aurata the Mint Moth and Diaphora mendica the Muslin Moth. Pictures of a couple of them below. Unfortunately I did not manage to see the Small Blue as seen by a few the people there.

Whilst I was at Kithurst Neil Hulme kindly pointed out the nest of a Mason Bee. It was a good tip and whilst photographing the Dukes close by I had some good views of the bees in action. See the next blog for details.

Pearl-bordered Fritillary

For me the emergence of the Pearl-bordered Fritillary marks the start of the butterfly season. There are butterflies on the wing earlier in the year, Brimstone, Comma, Peacock, Small Tortoiseshell and Red Admiral that have spent the winter hibernating. Holly Blues are in the garden, Dingy and Chequered Skippers as well as Green Hairstreaks and even Duke of Burgundy are out on the downs.


Lots of butterflies flying but the Pearl-bordered is the first one that I have to search for and there is always the fear that it may not be there. Lockdown posed a problem this year but I have been good so far so the short drive over to Rewell Wood seemed like just reward.

Slightly worn Pearl-bordered Fritillary

It was good to see that they were still there and in what appeared to be increasing numbers. I saw somewhere between twelve and sixteen specimens in a couple of hours searching as compared to six or seven years ago when you would be lucky to spot one or two flying.

As butterflies go it was as annoying as ever. You see them in the distance, some even come close but they have an uncanny ability to just change direction and seemingly disappear completely, right in front of you. I also got there too early in the day and the males seemed hyperactive. The best picture I managed was the slightly worn specimen above. The shot below is from a previous year and shows a more pristine image.

My suggestion is aim for mid or late afternoon when the males are starting to tire and can be found nectaring. Stake out a patch of Bugle and wait for them to come to you. If you are worried about self isolating, the woods were very quiet, I only saw one other person in the time I was there.

A better specimen from 2018

It was also nice to get a decent shot of a Lesser Treble-bar, one of the day flying moths.

Having found my main target for the day I decided to call in at Kithurst Meadow, on the way home, to see what else was about. The Duke of Burgundy is a much more accommodating butterfly. It doesn't fly very far or very fast and seems quite happy to pose for pictures although not always on such a good perch as the one below.

Dingy Skippers were easy to find but the only Chequered Skippers  I saw were two that were involved in an aerial skirmish which gradually took them away down the hill and out of sight.

Not a bad start to the butterfly year but the most impressive thing is the continuing recovery of both the Pearl-bordered Fritillaries and the Duke of Bugundys. Work in West Sussex by the Butterfly Conservation Organisation and some of the more enlightened landowners is really starting to have an impact.                                                                                                                                                         

Dukes and Frits

The Butterfly season really gets off to a start with the emergence of the Orange Tips but it's a couple of weeks later that the action really starts. The first spell of warm weather results in the emergence of a lot of the early season butterflies. A visit to Kithurst Hill and Rewell Wood at the end of last week proved a bit disappointing with nothing found. A quick visit to Mill Hill on Monday gave me Dingy Skipper, Grizzled Skipper, and Green Hairstreak, plus a few Small Heath and a lot of day flying micro moths. Good sightings but not many picture opportunities.

A few days of sunshine over the weekend and today we returned to Kithurst and Rewell Wood confident of finding our target species, the Duke of Burgundy and the Pearl Bordered Fritillary. First stop was Kithurst and as we walked into the meadow, it was clear from the number of people already there, that the butterflies were on the wing.

Duke of Burgundy

If you can find them Duke of Burgundys are an easy butterfly to photograph. They get up late, don't move around much, go to bed early and seem quite content to sit for long periods to have their pictures taken. The only problem was that we were at risk of having more photographers then butterflies.

Pearl-bordered Fritillaries are a lot harder to photograph. They tend to be very active, fast moving, and have a remarkable ability to just disappear from sight when you are watching them from only a few feet away. Also, Rewell Wood is not the easiest place to get to. There is very limited parking unless you use the layby at Fairmile Bottom and walk in over the hill. Hard work on a hot day.

Pearl-bordered Fritillary on Bugle

To find the butterflies you are looking for a broad sunny ride alongside an area of felled or pollarded trees with one or two years growth on the cleared ground. It is not worth chasing the butterflies into the undergrowth. It is best to wait until they come out to nectar on the Bugle growing along the ride.

The pictures are always better when you find freshly emerged specimens. Also seen at Kithurst Meadow where a few Dingy Skippers, plenty of Brimstones and a couple of Common Blues.

A good start to the butterfly season. The next challenge is to add the Small Pearl-bordered Fritillary to the Sussex list.

Duke of Burgundy

Good conditions for butterflying this morning. About 13°C with broken clouds and sunny spells. A good chance of finding butterflies before they became too active and an opportunity to improve on my year list.

First Stop was Rewell Wood for the Pearl-bordered Fritillaries. I always find the Pearl-bordered here but it sometimes takes some searching. Fortunately I was on a working party in the wood about 18 months ago cutting scallops for the butterflies to move into and it seemed like a good place to start.

There was nothing moving when I got there but then the sun came out and they began to appear. I think about twenty five sightings with a max of five butterflies in the air at any one time. It looks like another good year for the Pearl-bordered.

Pearl-bordered Fritillary

The pearls are on the underside of the wing but with these butterflies just warming up none would oblige with a closed wing shot. The problem is that once they warm up they become very active. They move quickly, they do not put down much, and they have a habit of just disappearing in front of your eyes. So I decided to cut my losses and move on.



Next stop was Kithurst Hill to look for the Duke of Burgundy. No rush here, the Dukes are late risers and it's not worth looking much before eleven o'clock. Fortunately I found a Green Hairstreak to keep me busy, my first of the year,

and there were a few Dingy Skippers flying in the meadow.

The Dukes are easy butterflies to photograph. They do not fly very fast or very far and they usually return to the same small territory where they are happy to sit whilst you take your pictures. But don't be fooled, anything flies into their territory, particularly another Duke and they are off in hot pursuit.

Duke of Burgandy

The Dukes are the only members of the Metalmark family to be found in Europe. They were in serious decline but the last couple of years has seen them expanding their territory in southern England. Butterfly Conservation and its teams of volunteers are restoring habitat along the downs and the butterflies seem to be taking advantage of the opportunity.


Only one Blue seen today, a Holy Blue passing through the meadow. Traditionally I see the Dukes and Pearl-bordered on the same day in early May and I usually manage to find a Small Blue at the same time. No such luck this year.
