Thanks for the comments Wurzel and Pauline

...my apologies for the late response, I have been away for a few days
I think that is the way the light is catching the BBYU Pauline. They have really attractive deep orange hindwings which so far I have totally failed to get a photo of

Arnside Knott 30th & 31st July part 1 – Scotch Argus.
On Sunday (29th July) we set off up the M6 for a couple of days at Arnside. After weeks and weeks of no rain here at home in the Midlands the heavens opened up on Sunday and down it came. With a forecast for rain for most of the day we decided to leave it until around midday before setting off and after passing though a couple of spells when it really lashed it down on the way up the M6 we turned off the motorway 3 hours later for the Arnside & Silverdale area in dull, cloudy and drizzly conditions. With a bit of time in hand before we could check in at our B&B we stopped off at Warton Crag for a quick look, although to be honest I wasn't expecting to see much in the less than favourable conditions. I went for a quick walk along the path through the woods and out onto the slopes and found that the higher I went the windier it became until it was blowing a gale on the higher paths.
Nevertheless, I did find a few butterflies with a couple of Speckled Wood and singles of Small Skipper, Meadow Brown, Comma, Red Admiral and Painted Lady all briefly seen before the wind whisked them away. A handful of Common Blues were also hunkered down in the grassy area by the car park.
The following morning (July 30th) was again dull and drizzly but with a forecast for some brighter weather in the afternoon, so we decided to spend the morning at RSPB Leighton Moss which is just a few minutes drive from our B&B, before heading up to Arnside Knott later.
During the few days before heading up to this area I had been wondering how it had been affected by the hot and dry weather that most of the country has had this year and it soon became obvious that, along with the rest of us, they have suffered from a lack of rainfall, with water levels at Leighton Moss being the lowest I have seen there.
Moving on to Arnside Knott just after midday I saw that the hillside was brown and parched which the rain over the weekend had done little to alleviate. The clumps of marjoram that so often attract butterflies here were mostly shrivelled and on their last legs and apart from a couple of small stands of hemp agrimony it was ragwort that was providing most of the nectar sources.
Over the next couple of hours the weather was mixed with some nice sunny spells but also a couple of drizzly showers with the temperature rising up to around the high teens. I had seen Scotch Argus being reported for a week or so before coming up but apparently not in high numbers and I had been wondering what I would find this year. Back home, numbers of some of the 'browns' and skippers seem to have been hit by the dry conditions and I wondered if this would be the case with the Scotch Argus here. I did a circuit of the sheltered clearings where I have always had success in the past and although I found maybe 12-15 scattered about they appeared to be flying in much lower numbers than I have seen here in previous years.

The following morning was a bit warmer with some good sunny spells, but with more cloud forecast to build up in the afternoon I decided to make the most of the morning and return to the Knott again. Arriving just before 10.00 it was warming up nicely although it was a bit breezy, as it often is on the more exposed parts of the Knott, and it was not long before I was seeing a few Meadow Browns and Gatekeepers flapping about.
As on the previous day, I did a circuit taking in the usual 'hotspots' but despite the better conditions, numbers were still low with no more than 20 at most seen scattered widely about during the couple of hours I spent here.
This is a species that soon begins to look worse for wear with scuffs and scratches showing against its dark ground colour and many of those seen, both this morning and the previous afternoon, were getting quite worn and faded with some looking like they had been around for some time. Also, the sun kept coming in and out from behind the clouds leading to rapidly changing light conditions which, along with the breeze, meant that getting a half decent photo was a real challenge.

I have already mentioned the dry conditions this year and how it seems to have hit the numbers of some of the species with grass feeding larvae and I suspect this is the case with the Scotch Argus here as well. Also, I couldn't help but notice that the usual prime spots here were becoming choked up with brambles and encroaching scrub which would also be having an adverse effect.
During my wanders around the Knott I met a number of people, including members of both Cumbria and Lancashire BC branches who all expressed concern about the low numbers of Scotch Argus this year. In fact, it appears that numbers have been dropping steadily for a number of years now, a fact that I have noticed on my visits over the past couple of years when I have seen dozens compared to the hundreds I was seeing when I first started coming here. The opinion was expressed to me more than once that the conservation focus has centred on the High Brown Fritillary in this area with the plight of the Scotch Argus here seemingly going under the radar and that the species could be lost from Arnside Knott if the current trend continues.
Whatever the truth is, and I suspect that a combination of the habitat becoming less favourable has been exacerbated by the dry weather this year, there is no doubt that something is not right and I was a bit surprised at how few Scotch Argus were flying here this year..
I really hope that I am wrong and that the Scotch Argus population on Arnside Knott recovers, particularly as it is one of only two sites where it can be seen in England.
At least, from what I was told, there are good numbers flying this year at Smardale Gill.
Of course, I also saw other butterflies up there...
Bye for now,
Neil.
