Hi every one, i`m new to this forum malarky so please bear with me if my photo`s don`t show up at the same time as my threads? I was tending my daughters vegetable garden and found lots of caterpillars. All Black and Yellow and furry. About an inch and a half long. They were happily munching there way through the Brussel Sprout plants!!! Can anyone tell me what they are. Also there was one green caterpillar about an inch long? HELP
