I hadn’t seen any Common blue butterflies at Cosmeston for over two weeks … until yesterday, when I spotted this little chap amongst the dying wildflowers and drying grasses. So, will he be the last Common blue for 2018?

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).
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!

#30DaysWild, 30 Days Wild, Blue-tailed damselfly, Broad-bodied Chaser, Common blue butterfly, Emperor dragonfly, Large Red damselfly, Large skipper, Lavernock Nature Reserve, Six-spot burnet, Small copper, Speckled wood
Day 12 of my #30DaysWild was spent wandering around the nature reserve at Lavernock. Though it’s not yet the riot of colour it will be in another month or so, many wildflowers are already blooming, including the Common spotted and Pyramidal orchids, and plenty of critters were feasting on nectar and pollen.
Today’s highlights included my first Six-spot burnet moth of the year, which was dazzling in the bright sunlight, and my second Small copper butterfly, a rather tatty looking specimen but still lovely to see. The Large skippers, Common blues and Speckled woods were abundant, and I also saw whites, a Brimstone and several Meadow brown butterflies.
The pond was alive with dragon- and damselfly action, with both a female Emperor and a female Broad-bodied chaser ovipositing. There were three male Broad-bodied chasers constantly squabbling over territory and a Four-spotted chaser trying to avoid them all. Damselflies included Large reds, Common blues, Azures and Blue-tailed. ’Twas a very lively place today!

Day 9 of #30DaysWild saw me at Grangemoor Park, a place that used to be Cardiff’s rubbish dump: when it closed in 1994, it contained an estimated four million cubic metres of garbage, both commercial and household. Now, it’s not only a public park but also a SINC (Site of Importance for Nature Conservation), and is home to a wonderfully diverse range of flora and fauna. My photos show just some of what I discovered there today …

#30DaysWild, 30 Days Wild, Aberbargoed Grasslands, British butterflies, British moths, Common blue butterfly, Large white butterfly, Long-horn moth, Nemophora degeerella, Small copper
On day 8 of #30DaysWild I paid my first visit to the Aberbargoed Grasslands, with my friend Sharon. We were hoping to spot some of the Marsh fritillaries this National Nature Reserve is known for but, sadly, we didn’t even see one. Perhaps the overcast weather had sent them into hiding. The good news is that I saw my first Small copper butterfly for the year, we saw a small number of Common blue butterflies and a few whites. We also spotted several moths, the most spectacular of which was a group of five male long-horn moths, Nemophora degeerella. They were dazzling, even on a grey day, and just look at the length of those horns!

Azure damselfly, Bird’s-foot trefoil, Bugle, Common blue butterfly, Common whitethroat, Coot, Cosmeston, Cosmeston Lakes Country Park, cuckoo spit, Dingy Skipper, Flax, Hawthorn blossom, Large Red damselfly, Mallard ducklings, Scarlet pimpernel, Swallow, tadpoles
I literally dipped in and out of Cosmeston on 2 May, for a quick look at the dipping pond to see if I could spot any Water voles. I dipped on the voles but I did see Ma Mallard and her two gorgeous ducklings, and a gazillion tadpoles.
11 May I needed to stretch my legs after spending the previous day sorting out after my birding trip so off to Cosmeston I headed. I came in from the north end via Old Cogan farm, where a pair of Swallows was sitting on the wires. I suspect they nest in the old barn as I see them there often over the summer months.
Apart from those Swallows, it was quiet on the bird front and, as a cool wind was blowing, there were no butterflies about either. So, I took lots of photos of newly blooming wildflowers …
While doing that, I found an interesting little critter mooching around on some leaves (it looked like a weevil without a long snout but I haven’t positively identified it), and I spotted my first cuckoo spit of the season (I just know you’ll be delighted with that find!).
15 May A brief walk through on my way home from Lavernock. I wandered along the edges of Sully brook and then, once again, stopped for a few minutes at the dipping pond. The bad news was that mother Mallard only had one duckling remaining – fingers crossed it makes it to adulthood. The good news was that I saw my first damselflies for the year – both Azure and Large reds were out in numbers.
17 May I passed through Cossie again, this time on my way home from Sully. A Common whitethroat was showing well in the reeds near the cafe, and a Coot was shepherding her three young offspring around the west lake. The chicks were well developed, which bodes well for their survival.
20 May This time my 3-hour mooch was all concentrated at Cosmeston. I went early to avoid the Sunday crowds and the scorching sun, and walked the east and west paddocks from one end to the other and back again, along the various trails. I was looking particularly for orchids but saw only leaves, a few with the stalks of flower buds just emerging, and for butterflies. The Dingy skippers and Common blue butterflies were out in good numbers, and it was a pleasure to watch them flitting to and fro.
24 May I went early again to Cosmeston but not early enough, as the rain came in almost as soon as I arrived and I didn’t have a coat with me. I lingered long enough to enjoy the glorious Hawthorn blossom that covers the hedgerows like summer snow, before striding quickly homewards.

Anthocharis cardamines, British butterflies, butterfly, Celastrina argiolus, Common blue butterfly, Holly blue butterfly, Large skipper butterfly, Ochlodes sylvanus, Orange-tip butterfly, Polyommatus icarus
Though summer is well underway here in Britain, I’m not seeing a huge number of butterflies. Here are some I have seen fluttering by in recent weeks.
There are several small blue butterflies in Britain and they can be difficult to tell apart but the Common blue (Polyommatus icarus) is, as its name implies, the most common. As is often the way with wildlife, the males are bright blue, whereas the females can be quite a drab brown.
The Holly blue (Celastrina argiolus) looks quite similar to the Common Blue, especially in flight. The trick to identifying it is in the small black dots on the underwings. It is also the blue butterfly that emerges first from its winter hibernation so look for it near holly plants in early spring, then fluttering about ivy in the summertime.
If this is an Orange-tip butterfly (Anthocharis cardamines), where’s the orange colour? Turns out this is a female and only the males have bright orange wing tips. Still, she’s a very pretty little thing, even if she did seem a bit shy and hid her head behind a leaf.
Though it’s called the Large skipper (Ochlodes sylvanus), this butterfly is relatively small, its wingspan just a couple of millimetres more than the Small skipper, so you need to look for the mottled brown markings on its upper wings to tell the two apart.
