The 58 - Episode VIII - Relentless progress

Sunday, 24th May 2020

Before continuing the saga of the search for all 58 Great British butterflies it may be worth summarising the situation.

Approaching the end of Spring our hero had seen and positively identified 38 species. Just the 20 to go!

Everything seemed to be going well but there were a few concerns; High brown fritillary being at the forefront of these.

Another was Small white, a relatively common butterfly, which had so far evaded our hero, even though those assisting him in his quest had already seen them. This was a source of amusement to us but great frustration to Jim.

We are allowed to have a bit of fun at our hero's expense.

On the last day of Spring I went on holiday and our hero went to Furber's Scrapyard.

A couple of years ago Natural England and Shropshire Wildlife Trust were awarded funding to acquire land abutting Whixall Moss to enhance the well-being of the moss. Part of the acquisition was the disused scrapyard. We have visited the site a couple of times to carry out surveys but on this occasion Jim ventured there alone.

His trip was rewarded with:

Number 39: Ringlet

On the following day our hero, with Bob as companion, ventured north to Meathrop Moss which lies not far from where the River Kent flows into the north of Morecambe Bay.

Information about the site can be found by following this link - Meathrop Moss

The reason it drew the attention of our butterfly hunter is that it is a good site for the Large heath butterfly. On this visit plenty were seen flitting about the site, but only one posed long enough to be photographed.

Number 40: Large heath

Large heath can also be found, more locally, at Whixall Moss.

A few days later the pair were off on another jaunt. This time to Daneway Banks, a Gloucestershire Wildlife Trust site well known as a site for Large blue butterfly. For more information on this site follow this link - Daneway Banks

Not many years ago this butterfly was extinct in Britain but it has been reintroduced into a few reserves from stock taken from Sweden.

Parking at Daneways Bank is very limited and our hero, finding the car parking spaces full, dropped off his companion and went to find a safe place to park. By the time that he had done this and returned Bob had found and photographed a Large blue.

Jim was not so lucky, he was unable to capture a photograph where the butterfly had open wings but he did manage a more distant shot of the underwings.

The site is also known for another rarity, a bee fly, Villa cingulata. With careful study of the low vegetation you can spot them going about their business. This one is a female which is ovipositing.

To show that he was thinking of me in my absence Jim also found this colourful mirid bug Calocoris roseomaculatus.

Two days later our intrepid duo were out again, this time, locally, at Prees Heath to look for Silver-studied blue. The stronghold of this butterfly is the heathlands of the south but there are other colonies dotted around, one of which is Prees Heath.

The reserve is managed by Butterfly Conservation principally for this butterfly and hundreds can be seen there if you go at the right time and the conditions are suitable. follow this link for more information about this site - Prees Heath

And, yes, our duo did go at the right time and in the right conditions to confirm:

They also checked some oaks in a small woodland area and found:

I was now back from holiday and our hero had decided that his next target would be another tricky butterfly to find for someone living in the West Midlands - Lulworth skipper. Unlike the other skipper named after a place, the Essex skipper, which can be found well away from its named locality, the Lulworth skipper is confined to extreme south of Dorset centred around Lulworth.

The trip was planned, the weather forecast consulted and a day chosen. Unfortunately it was on my birthday, so I declined to join our hero. For some reason his other regular companion also decided not to go, leaving Jim to make the journey on his own.

Did this put him off.

Of course not!

Setting off about 6,20am our hero arrived at his chosen destination, Durlston Country Park, five hours and 188 miles later. Jim has provided me with a description of the route he took. I will not go into detail here but it is fair to say that some of the roads, designated as A roads, provided challenging conditions, being at certain points narrow and not wide enough to accommodate cars and lorries passing in both directions.

Having arrived at the Country Park Jim takes up the story ...

From the car park I made my way into the main park. Within 100 yards I could see only a few people, the Isle of Purbeck rolled ahead of me towards Worth Matravers and beyond, beautiful downland. A breeze towards the sea (!) and warm sunshine, what a perfect spot. Dark Green Fritillaries looked so out of place and there were skippers. I tried so hard to identify a Lulworth Skipper, almost succeeding a time or two. But onwards to the west! I was pretty much on my own by now, lots of butterflies, lots of skippers, and then the first Lulworth Skipper, so obviously a Lulworth Skipper, there was a large amount and variety of nectar sources but the breeze was a problem, if a butterfly got into it then it was 20 yards away in the blink of an eye. Large, Small and Essex Skippers in profusion. I walked most of the way to St. Aldhelm's Head then slowly back nearer the edge of the cliffs.

The results of this outing were:

Number 45: Lulworth skipper

By the start of July relentless progress had been made. Only 13 to go. An unlucky number?

Still no High brown fritillary or Small white. And there were a few other tricky butterflies coming into their flight season. The pressure was mounting.

Like our hero you will have to fret another week to find out how he got on.

And now for some of the photographs that have come my way this week, plus a few of my own, for your enjoyment.

Following my ascent of Little Hill to confirm that Callicera rufa were still in residence, I made the trip to Grinshill where the Scot's pine are about 50 yards from the car park to check that they were still present there. The drawback of Grinshill is that there is not a single dominant tree the hoverfly may use, resulting in having to check a good number in order to find the distinctive insect.

The good news is that I found them on three trees.
