Cabbage white caterpillars

Six Cabbage White butterfly caterpillars trying to look innocent after munching a hole in a Nasturtium leaf! Nasturtium is known as a trap plant, as it can divert insects like these away from brassicas, like cabbages, if you plant them in your vegetable patch. 

Not only can they help protect your crops from damage, they look really good, as well, with bright orange and yellow flowers. These are edible and can be added to salads.
