I’ve been saving this photo, taken quite recently, on 22 September, for just such a day as this. We are currently under the thumb of Storm Alex, the Met Office having issued a yellow warning for heavy rain and wind gusts over 20mph until midday tomorrow. So, to me, this is the perfect day to post this gorgeous Peacock butterfly, a heartening splash of bold cheery colour.

Aricia agestis, British butterflies, Brown argus, butterfly, butterflying, Cosmeston Lakes Country Park, Lavernock Nature Reserve, second brood Brown argus
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!

I love the peculiar habit Small coppers have of walking head first down the stems of grasses.

British butterflies, butterfly, Comma, Comma variation hutchinsoni, Polygonia c-album, Polygonia c-album var. hutchinsoni
If you happen to see a Comma butterfly on one of our fine autumnal days, have a good look at the colour of its wings. You may notice that both the upper and the undersides of its wings are quite dark, particularly when compared to some of the Commas you saw in the summer months. Why is that?
It may be that your paler summertime Comma was a hutchinsoni. The splendid Life Cycles of British & Irish Butterflies explains:
The Comma is known for a particular form named hutchinsoni that is much paler in appearance on both upperside and underside that the nominate form. This form is found throughout the butterfly’s range and is normally attributed to individuals that go on to produce a second brood in the same year. Its name is a tribute to Emma Hutchinson, a renowned Victorian entomologist … who ultimately discovered its double-brooded nature and the corresponding variation between broods. The name was announced by J.E. Robson in 1881 in The Young Naturalist: ‘The Summer form is so different, and so constant in its appearance, that it ought to have a distinctive name, and we suggest it be called var. Hutchinsoni, in compliment to the lady … whose knowledge of the species is not exceeded by that of any one living.’
In my photos, the Comma on the left, Polygonia c-album var. hutchinsoni, was photographed on 24 June, the Comma on the right on 17 September, both in the same location and on fine, sunny days. I think you can see how marked the difference in their colouring is.

aberrant Meadow brown, British butterflies, butterfly, Comma, Green-veined white, Painted Lady, Red Admiral, Small copper, Small tortoiseshell
To celebrate – or, perhaps, to mourn – the last calendar day of summer, here’s a tribute to some of the beautiful butterflies I’ve seen in recent days, just because, when they’re gone, I’m really going to miss their magic.
A Comma doing what they do so well when their wings are closed – blending in.
Most of the white butterflies I’ve seen lately have been Small whites so this Green-veined white stood out from the crowd.
Here’s another that stood out – an aberrant Meadow brown. There always has to be one!
The heat wave a couple of weeks ago seems to have brought in a small influx of Painted ladies, though nothing like the numbers we had last year.
Have you ever noticed how much Red admirals like blackberries? And their colours blend in to this background rather well.
Small tortoiseshells have been having a good year locally, which has been a real treat. I even found two feeding on Red valerian right at the edge of one of the local beaches this morning.
A delightful surprise from Saturday’s walk at Cosmeston, a pristine Small copper.

I had hoped the recent combination of southerly winds and heat wave would bring a wave of migrants to our shores and it did. The most exciting for me was the Clouded yellow butterfly. I saw my first on 10 August but, as is often the case with these beauties, their rapid flight can make them difficult to photograph, and this one flew over a fence into a shrubby area, disappearing immediately. My next Clouded yellow sighting came on 16 August, in a different location but with almost the same result – over the fence and gone! I managed to grab a single ‘record’ shot, below.
Then, last Monday 17 August, I got lucky. I did have to follow this Clouded yellow around a sizeable field, watching intently, not following too closely so as not to spook it, waiting for it to settle but, finally, it paused briefly to feed and I got my photograph. They are such lovely butterflies, so different from anything else in Britain – I just wished they lived among us.

British butterflies, butterfly, Dingy Skipper, second brood butterflies, second brood Dingy skipper
In 2019, when I began keeping records of all my sightings and focused seriously on searching for and recording butterflies, I saw my first local Dingy skipper on 30 April and my last on 10 June. This year, I spotted my first on 6 May and what I thought was the last on 26 May, a relatively short season.
Then, remarkably, on 24 July, I saw a pristine, obviously newly emerged Dingy skipper, and I’ve seen two more this week, one on 4 August and another the following day. These are second brood butterflies, the product of the breeding of the butterflies seen in May.
In his brilliant book Life Cycles of British & Irish Butterflies, Peter Eeles write that ‘Good summers may … result in a partial second brood in southern England that emerges in late July and August (a second brood is the norm in Southern Europe), and this may become a more frequent and widespread phenomenon in Britain and Ireland with a changing climate’. It seems, here in south Wales, that phenomenon is already happening.

British butterflies, butterfly, butterfly egg, Common blue butterfly, Common blue butterfly egg, Painted Lady, Painted lady egg, thistle
This Painted lady is only the fourth individual I’ve seen this year but she was by far the best, not because of her appearance, which is a little ragged around the edges, but because she was laying eggs … and I’d never seen a Painted lady egg before.
At just 0.65mm high, the egg is tiny and, in my reference book, it’s described as green but, to my eye, this one is more of a pale turquoise – the plant stem is green. And the plant is a thistle – Creeping thistle, I think, though it was a young plant with no flowers, which makes it harder for me to identify but probably more nourishing for the teeny tiny caterpillar to munch on when it emerges. Now if I can only find this exact plant again in approximately a week’s time …
And following hot on the heels of finding that Painted lady egg, today I spotted a female Common blue butterfly laying her eggs in a sheltered clearing. You can perhaps see in the photo how she is angling her body to deposit an egg underneath the foliage.
So, once again, I was able to find the newly laid egg and take some photos. According to my book, these eggs are usually 0.5mm in diameter and just 0.25mm high, so really tiny. I have no chance of finding this egg again but I’m really glad I had the chance to see it.

British butterflies, butterfly, butterfly in Oak trees, Cosmeston Lakes Country Park, Favonius quercus, Oak butterfly, oak tree, Purple hairstreak
The key to where to locate this gorgeous butterfly, the Purple hairstreak, is in its scientific name Favonius quercus – quercus is the genus of the Oak tree – and I suspect that there are many more colonies of Purple hairstreaks living in our old Oak trees than we currently know about, as these butterflies spend much of their time unseen, high in the leafy boughs, feasting on honey dew.
There is a colony at Lavernock, and I’ve seen these butterflies at a couple of locations along the road that leads to Lavernock Point, but they were the only local sites I knew about. So, you can perhaps imagine my delight when, during Thursday’s walk at Cosmeston Lakes Country Park, I came face to snout with a female Purple hairstreak, which had ventured down to head height, and was happily running her yellow proboscis over the honey-dew-covered leaves.
This was the closest I’d been to one of these lovely creatures and had previously seen neither the purple sheen on their open wings nor the yellow proboscis. I was in butterfly heaven!

I am constantly reminded of how transitory life can be for the smaller creatures that share our planet. Take, for instance, the Ringlet butterfly. The adults usually emerge in the second half of June and only a few survive into August. In their few short weeks of life they experience a frantic rush to reproduce …
… a time full of danger from pecking birds, of collisions with damaging foliage …
… before death takes them – unless, like this rather ragged creature, they are caught in a spider’s web, die prematurely but, in so doing, give life to another creature.
