Also known as the 'Cabbage White', the foodplants of the caterpillars of this butterfly are members of the cabbage family, known as 'Brassicas', hence its Latin name, Pieris brassicae.

If you want to keep Large White caterpillars at bay, try placing horticultural fleece over your vegetables to stop the butterfly laying its eggs on them. You can also pick off the caterpillars, which are hairy and yellowy-green, with yellow stripes and black spots.
