PIERIS DAPLIDICE.
This butterfly resembles the rare English specimen Bath White. It is very common in some years,[2] and found in most localities from February to October. It seems mostly to frequent rough poorly-cultivated fields. The wings are white, the fore-wings having a large black spot in the middle, and being bordered with black encircling distinct white spots. The markings of the under-side show through on the hind-wings, and these have black markings on the edges in the female. The underside has a ground colour of sage-green, freely spotted with white. The markings show considerable variety, some being marked much more heavily than others. It measures across the wings from two to two and a half inches. The caterpillar, which is greyish green, has yellow stripes on the back, and feeds generally on cabbage. The butterflies are much pursued and destroyed by dragon-flies.
[2] During the winter of 1892-1893 it was met with in great numbers.
