Cabbage White butterflies

A female cabbage white butterfly, on the left, mating with, you guessed it, a male on the right.
These are the most common butterflies in North America although they are imported - accidentally via a cargo ship to Quebec in 1860 - within a couple of decades they were everywhere.
Considered a pest since they consume valuable crops they are loved by all those of us who can remember chasing them in childhood.
