A Brown argus pair

The Brown argus butterflies seem to be having a very good second brood locally, at least in those places where the habitat has survived the heatwaves and drought. Lavernock Nature Reserve is one such place, very wet and muddy underfoot in the winter months and still remarkably lush despite this summer’s weather.

I can’t remember ever having seen a mating pair so, when I saw these two, I waited and hoped they might get together. The male didn’t move from where he had been perched when the female flew in and landed further up the plant stem. She fluttered her wings a lot and came flouncing down the stem towards the male. He still didn’t move. The next thing, the female was pointing her abdomen stiffly upwards, the standard indication that a female butterfly doesn’t want to mate. Why she bothered to approach him at all, I have no idea, but it was still lovely to see the two so close together.

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!
