Cabbage white butterfly on a Purple Buddleia flower
The Large White is one of two species (the other being the Small White) that can claim the title of "Cabbage White" that is the bane of allotment holders all over the British Isles. The larva of this species can reach pest proportions, and decimate cabbages to the point that they become mere skeletons of their former selves. The female is distinguished from the male by the presence of 2 black spots, together with a black dash, on the forewing upperside. This is one of the most widespread species found in the British Isles and can be found almost anywhere, including Orkney and Shetland. This species is also known to migrate to the British Isles from the continent, augmenting the resident population in the process.
