Mr C kept seeing a small blue butterfly in the watermeadow. I hadn’t seen it, but I saw this one the other day, which turned out to be the female common blue. There are lots of blue butterfly species. I was able to identify this one by the pattern of dots on the underside of the wings. The female common blue is a brownish colour with a dusky blue body. Mr C probably saw the male, which is forget-me-knot blue with a white trim.
