  • Cuckooflower
  • Nasturtium (Tropaeolum majus)

Adults take nectar from a range of flowers including:

  • Bluebell
  • Bugle
  • Cuckooflower
  • Red Clover
  • Thistles

Where does it spend the winter?

Green-veined Whites spend the winter as chrysalises, usually attached to plant stem and low to the ground, though occasionally stuck to a tree trunk or a fence.

about the Green-veined White

After mating, male Green-veined Whites release a pheromone (scent) onto the female which makes her less attractive to other males.
