I was so excited just now, to find this beautiful caterpillar of the Comma Butterfly in my garden. There is a shot of a butterfly further back in my gallery.(Orange with brown spots)The one that looks like bird poo.The caterpillar was going around the sun-dial. It is a blackish brown with orange banding and orange bands at the front. Further back it has white spikes with a white back. The caterpillar feeds on nettles and as I have a nettle-patch just for this purpose I released it back there.
