Ragged royalty

Barra for an American Redstart would have been a bridge too far this weekend: Brighton was a more practical destination to see a new species for me in Britain: a Queen of Spain Fritillary butterfly. It's difficult to believe that almost eleven years have passed since I saw my last new British butterfly. That was a Monarch, one of which was just around the corner from a Long-tailed Blue I found earlier in the day on the Isles of Scilly back in October 2006. A few days after that, a Queen of Spain Fritillary was also seen on the islands near the Trenoweth flower farm but despite much searching I was unable to find it.
Male Queen of Spain Fritillary - it looks like it survived a bird attack judging by the state of hind-wing on the right hand side

Details of a sighting of three of these rare migrants at Halcombe Farm near Piddinghoe first emerged two weekends ago and was immediately of interest. Unfortunately, the news broke the day before the gloriously sunny Bank Holiday Monday - not the sort of day you want to be driving along the south coast, and I couldn't get away in any case. Last weekend was equally compromised, as being on call for emergencies meant that I was unable to leave Dorset.
The species is known for spending much of the time basking on the ground: this one was no exception
A brief bout of nectaring provided one of the few opportunities to get a shot of the bold silver spots on the underwing
Discussing the survival chances of the fritillaries with Phil Sterling during the week, he was pretty convinced that unless the weather turned really foul, they would still be present this weekend. So with one eye on the forecast, and the other on Butterfly Conservation's excellent Sussex branch website, I resolved to go on Saturday as full sunshine was promised throughout the morning. Internet updates suggested that two individuals were still present on Thursday, both looking more than a little worn, and that was enough to persuade me to make the effort of an early start to beat the traffic yesterday morning.
This Clouded Yellow was one of 15 butterfly species on view at Halcome Farm

I arrived at Halcombe Farm around 0900 and began combing the area around a bonfire which was being used as a lek site by the fritillaries - all three having been identified as males. As the morning warmed up, a Clouded Yellow landed nearby but there was no sign of the fritillaries. Other butterflies, and then another butterfly watcher, arrived. We split up and shortly before 1000 he gave me a shout to indicate he had found one.

A male Common Blue was easier to see
Queen of Spain Fritillary is reasonably common on the near continent but still very rare in the UK with just a few hundred records and a small number of unsuccessful attempts at colonising documented. So despite the slightly ragged appearance of the visiting royalty, I was very glad I got to see one of the trio before their inevitable demise, particularly as the famous bonfire is apparently scheduled to go up in smoke within a matter of days.

Well done and thanks to the diligent transect walker, Dave Harris, who first discovered them, to Neil Hulme for getting the news and directions out to the wider world, and to the landowner Colin Appleton for allowing access to the site which has provided a lot of pleasure to many visitors over the last fortnight.

Sunday Blues

A late 'winter' cold put paid to any thoughts I may have harboured about wandering further afield this weekend, so I indulged myself on Saturday with Lemsip and a lie-in. Suitably refreshed and a little stir crazy by Sunday, I managed a gentle stroll around Ballard Down to get my quota of fresh air, flora and fauna. Encouraged by the results I have been getting recently with my '1st summer' 100-400mm lens, I also aimed to get some more butterfly photographs. And very rewarding it was too, despite the imperfect weather, with some interesting colour variants of female Adonis Blue among the highlights.
Female Adonis Blue - one of the bluest I have seen, a mesmerising aberration - apparently this is more common in spring broods
Another striking individual - even bluer than the one above, but with orange hindwing spots reduced in brightness - nectaring on Horseshoe Vetch, which is also the larval foodplant
A more conventional female Adonis
The stunning male Adonis Blue
A number of males were quite approachable in the cool conditions of Sunday afternoon
And finally, a pair of Adonis Blues doing their bit for the next generation
A male Common Blue - more lilac in colouration than the Adonis, and note how the white outer fringes to the wings are unbroken by black marks
A Common Blue roosting up in overcast conditions
This is a female Common Blue - like the female Adonis above, this one is at the bluer end of the spectrum

Don't be fooled by the name 'Brown Argus' - this was the third species of blue I saw on the wing at Ballard Down
Brown Argus underside - they were relatively inactive in the overcast conditions

Fortunately, this provided the opportunity for close study of roosting individuals - I love the rich orange spotting on the underside

Summer's last hurrah

The long summer seems finally to be coming to an end, in these parts anyway. Time, then, to celebrate it with a wash up of some Lepidoptera seen on holiday in Cornwall and the Isles of Scilly last month.
Clouded Yellow never perches with the wings open but this pair were attempting to mate near The Lizard (the 2nd individual can just be seen behind the leaf). By focusing in the right area and setting a high shutter speed I was able to catch the open wings as it flapped.
An even luckier shot of a Clouded Yellow in flight

A small proportion of female Clouded Yellows are of the rare white form helice - this one was on Peninnis Head, St Mary's. While superficially similar on the underwing, the difference becomes more obvious in flight - see Nick Hopper's excellent open-winged shot here on the Portland Obs post for 29th August.

Small Copper was one of the commonest butterflies on Scilly during August
Common Blue were also plentiful
And, to come full circle, another stunning Clouded Yellow, this one of 20+ on St Mary's in the short walk between Porth Hellick and the airfield.


On the subject of the airfield, the landing strip on St Mary's is pretty small: as you can see, barely room to swing an Otter.

In the footsteps of giants

Now summer's over (last week, you blinked, you missed it) it's time to reminisce about sunshine and butterflies. Between blinks last week, I managed a trip to Cerne Abbas, whose Giant is famous for his butterflies among other things. The chalk figure is thought by some to be a fertility symbol, and it seems to be working for the Lepidoptera this year at least. Good job too - they had an appalling year in 2012 which was ranked by Butterfly Conservation as 'officially the worst since records began'. The wet weather contributed to declines in 52 of out 56 species with moths faring just as badly - not just a problem for them but all the other critters that rely on them for food. Hopefully, the range of species and good numbers of each on show last week is a sign that they can bounce back quickly.
This Marsh Fritillary was freshly emerged - blood was still being pumped into the wings
