Large White Butterfly

The Large White is one of our common butterflies, this one is the female as it has two more prominent spots on each forewing than the male.

Large White butterflies enjoy a fairly wide variety of habitats, open areas as well as gardens. 

Apparently Large Whites like foods with mustard oil glucosides. This could be the reason for us thinking that they only fed on cabbage in the garden when we were young, as in those days they were known as Cabbage White Butterflies.
