This was taken by the side of the Weymouth Relief Road on 29/05/2017. This area is turning into a superb butterfly spot.
The caterpillar is that of one of the Burnet moths, probably the Six-spot. THe white blob on the other side of the stalk is a chrysalis cocoon of the same species.
Simon reports there were over 50 chryslis and a couple of caterpillars.
