This dark green caterpillar was captured as it attempted to gain access to church this morning. It had marched several yards across tarmac and concrete to get to the church door so it is impossible to know what plants it had come from. There is mixed woodland and rough weedy ground around the area. As can be seen it had a continuous yellow line round its body.
