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.
