Marline blues

Some of the second emergence of butterflies were on the wing when I walked through the meadows of the Marline Valley Nature Reserve (TQ781122) to the east of Hastings yesterday. I put up a small heath from the long grass and found orange-tip eggs on the lady's smock plants in some of the wet flushes.

I also came across what I think is a not fully grown caterpillar of a common blue butterfly (see photo above) feeding on bird's-foot trefoil. I will have to raise it at home to be certain of its identity, but if it is not a common blue I cannot think what else it might be.
