Pieris piotodice. Male. Under side. 



There is a good deal of variation in the species, and the sexes 

 are unlike, the male being almost pure white with a few dark spots, 

 while the females are clouded, and the veins on the under side are 

 margined with lines of yellow. This insect is not common in New 

 England, but in the west and south it may be seen flitting low over 

 the fields, or on the blossoms of weeds during the summer and 

 autumn.
