Many naturalists must have wondered what the
small, pretty black-and-white moth is that can be seen flitting conspicuously
in the woodlands on southern Vancouver Island in late March and April. This
is the one. They can sometimes be seen taking nectar from Erythronium
lilies. The eggs are laid singly on the leaves or buds of Blackberry Rubus
discolor or Thimbleberry R. parviflora. The caterpillars hatch within
ten days or so and they pupate after a further three weeks. The moths emerge
the following spring.
