Cloudless sulphur

phylum	Arthropoda	Phoebis sennae, the cloudless sulphur or cloudless giant sulphur, is a mid-sized butterfly in the family Pieridae found in the New World. There are several similar species such as the yellow angled-sulphur (Anteos maerula), which has angled wings, or other sulphurs, which are much smaller. The male butterfly is clear yellow above and yellow or mottled with reddish brown below and the female is lemon yellow to golden or white on both surfaces, with varying amounts of black spotting along the margin and a black open square or star on the bottom forewing. Once the egg hatches, a caterpillar emerges that is yellow to greenish, striped on sides, with black dots in rows across the back. For more information, visit the Wikipedia entry.
