Little Green Caterpillars!

[freefolk]

On checking the pots containing my spring cabbage and over wintering broccoli today, I found some leaves had been eaten, and the culprit was a tiny green caterpillar, about 1 - 2cm long. Could this be winter moth? If not any ideas? I have removed them, and they don't seem to have taken a fancy to anything else as I also have carrots, spring onions and radish in the bed.

I think they are more likely to be young caterpillars of the small white butterfly. They only eat plants of the brassica family, so your carrots and spring onions are safe from them. I'm not sure if they go for radishes, which are brassicas but not the same species as cabbage and broccoli.
