274/366 Another extra brood

This year I saw my first Brown argus butterfly (Aricia agestis) on 11 July and thought I’d seen my last on 26 August, a short but very sweet season of sightings. Then, to my astonishment and absolute delight, I discovered two more on the same day, 16 September, one at Lavernock Nature Reserve and the other at Cosmeston Lakes Country Park.

These had to be the product of the first brood of butterflies breeding and so were a second brood, not something I’d seen before with this butterfly. As the local populations of Dingy skippers have also produced a second brood and the Small coppers a third brood this year and nothing has changed in their environments, I can only assume this has been caused by the warmer climate.

I haven’t managed to find the Lavernock Brown argus again but the Cosmeston butterfly was still in the same spot last week. A late summer-early Autumn treat!

Though second-brood butterflies are still looking pristine, many of the others are now well past their best, as life is tough for such fragile creatures. Some butterflies are so battered that I’m amazed they’re able to fly at all, yet this Gatekeeper and Ringlet were still moving from plant to plant.

Birds looking for an easy snack often attack butterflies and it’s easy to see the tell-tale signs of bird pecks on butterflies’ wings, like those on these: a Ringlet, Comma, Small copper and Peacock, and another Gatekeeper.

Is it the blazing sun that has caused this Essex skipper’s orange to fade so dramatically or has it lost most of its wing scales?

I’m 99% sure this is the same Brown argus, seen first on 1 August and again on 10 August. It already had some bird pecks when I first saw it but, nine days later, it was looking rather faded and more than a little ragged around the edges.

This Painted lady is looking battered, bird-pecked, faded and jaded, perhaps the affects of a long migration journey, or simply a tough life well survived.

205/366 Sightings at Slade Wood

On Wednesday I ventured on to public transport for the first time in four months – suitably masked, of course – for a visit to Slade Wood, near Rogiet. This was a site where I’d seen Silver-washed fritillaries and White admiral butterflies last summer so I was hoping for more of those but, unfortunately, huge areas of the woodland have been felled over the winter months, which has destroyed a lot of the butterflies’ habitat.

I did still see a lot of butterflies on the Buddleja bushes – in fact, probably more Peacocks than I’ve seen in one day before, and I got some pics of a pair of Gatekeepers mating – but only spotted one Silver-washed fritillary (and didn’t manage a photo) and no White admirals. There was also a butterfly consolation prize in the form of a Brown argus, a butterfly that’s not common locally, which was in Minnett’s Field, a nearby meadow managed by Gwent Wildlife Trust.

Though the butterflies were a little disappointing, the birds were a huge bonus as I managed to find a family of Spotted flycatchers, with two adults and a couple of juveniles (below left), which I’d not seen before.

And the flycatchers were joined at their watering hole, a couple of muddy puddles, by two beautiful bright Siskin.

I may not have seen what I was expecting and I was saddened to see how many trees had been felled but I still had a wonderful day out. The sense of freedom was exhilarating, and Nature certainly didn’t disappoint!

196/366 First Brown argus of 2020

By this date last year, I had managed to find Brown argus butterflies at two different local sites (and one of those was the first Cardiff record in eight years). This year I only spotted my first Brown argus last Saturday, almost two months later than last year. The Polyommatinae family (that’s the blues and arguses) are not faring well in my part of south Wales this year, which is a great shame, as they are all gorgeous little butterflies.

If you’re having trouble telling a Brown argus from a Common blue female, my blog Flying on the wings of Confusion, July 2018, has ID pointers and photos that should help.

I’ve had a lucky week with my Lepidoptera sightings – that’s moths and butterflies, for those who didn’t know – and the week’s not over yet. As well as the Narrow-bordered Bee Hawk-moth on Monday and the Burnet Companions on Tuesday, yesterday I found my first (three) Large Skipper butterflies for the year at Cosmeston.

And, today, my wander around Grangemoor Park was something of a Lep-fest, with the first (five) Mother Shipton moths I’ve seen in 2019.

And I spotted a nice Latticed Heath moth trying to hide in the grass.

And, then, just as I was about to head for home, I noticed something small flitting about along a side path, went to investigate and found two Brown Argus butterflies, which I have seen already this year but not in Wales. You can see why I named this blog ‘leptastic’!

133/365 Birding on Salisbury Plain

Yesterday’s Glamorgan Bird Club trip to Salisbury Plain, RSPB Winterbourne Downs and Martin Down National Nature Reserve was amazing. The weather was stunning, the bird sightings were brilliant, as were the butterflies, and, as always, the company was wonderful.

The views from high on Salisbury Plain were lovely – we even had a distant view of the White Horse, though it was a little disconcerting being so close to the military impact area and to have the serenading of the plentiful skylarks occasionally shattered by the booms of exploding shells. The joy-riding trailbikers and off-roaders weren’t exactly peaceful either.

Still, we saw some amazing birds – I managed to spot the only Great bustard of the day (you’ll just have to believe me when I say that the head in the centre of the dip in the vegetation in the photo above is definitely a Great bustard!) and we had splendid ’scope sightings of Stone curlews and chicks at Winterbourne – both bird sightings were lifers for me. My best bird photo of the day was the Corn bunting shown below – captured out of the car window as we drove by.

We also enjoyed some superb butterfly sightings – my first Small blues and Brown Argus for the year, and, finishing on a high, my first ever (two) Marsh fritillaries at Martin Down.

Flying on the wings of confusion

In yesterday’s blog I mentioned my confusion in identifying the Brown argus butterfly. Here’s why, plus some tips on how to defuse that confusion.

One of these butterflies is a Brown argus (Aricia agestis), the other five are female Common blues (Polyommatus icarus). Can you spot the odd one out?

If you have keen eyes, you will have noticed a difference in the patterns of spots of the butterfly in the last photo, which is the Brown argus. The Common blues all have an extra spot on their forewings (below right) and, on their hind wings, the two spots on the leading edge are more spaced out than those of the Brown argus – its two spots have been described as being close to a ‘figure of eight’ shape (below left).

180726 underwing patterns

Now, let’s look at the open wing patterns, which I find even trickier. Two of these butterflies are Brown argus, four are Common blue females. Which are which?

Firstly, as you can no doubt see, the amount of blue on Common blue females is very variable and that alone cannot help you identify them, as the Brown argus can also have a slight blue sheen to its wings sometimes. What I have found is that there is much less, sometimes no white colouration below the orange markings on the lower wings of the Brown argus (below left) and, though the Common blue can show a slight dark spot in the middle of its forewings (below right), that spot is much less obvious than the Brown argus’s spot.

So, did you work out which was which in the open wing photos? The middle butterfly in each row (photos two and five) are the Brown argus butterflies. Top marks if you spotted them!

When I spotted this little Brown argus butterfly (Aricia agestis) in the RSPB reserve at Dungeness in Kent, I thought it was a first for me, but I was wrong.

It turns out I had actually seen one two days earlier during a walk along ancient footpaths in the Cuckmere Valley in East Sussex, but I hadn’t realised until I’d had a really good look at my photos.

And then, when I got home and rechecked the photos on my computer of another very similar butterfly, it turned out that I had actually seen my very first Brown argus at Cosmeston, my local country park, back in August 2017.

Why was I so confused? Check back in tomorrow and I’ll show you.
