This group contains more than 1000 species distributed in most parts of the world, and are often called Whites or Yellows.

Some Pieridae are well-known pests of the cabbage family (Brassicas) hence the name ‘cabbage whites’.

Male and females of the group often look similar to the human eye, but when viewed under UV light the males of some species, like the Brimstone, reveal hidden patterns. 

This characteristic demonstrates how butterfly eyes can see more in the UV end of the spectrum.
