In its larval stage, it's a pest of cole crops.
As an adult, it's like a little Cinderella.
That would be the cabbage white butterfly, Pieris rapae.
In the fairy tale, a ragged Cinderella lives with her selfish stepmother and two mean stepsisters. Cinderella wants to attend the palace ball, but has nothing appropriate to wear. So her fairy godmother waves a magic wand and transforms her into a beautifully gowned princess, complete with glass slippers. She rides in a magnificent carriage pulled by a team of beautiful horses, dances with the prince, and at the stroke of midnight (when the magic ends), she loses a glass slipper. You know the rest. It all ends with Cinderella and the prince exchanging marriage vows and living happily after.
This butterfly appears in the spotlight every January when UC Davis emeritus professor Art Shapiro hosts his annual "Beer for a Butterfly" contest. Collect the first live butterfly of the year in the three-county area of Sacramento, Yolo and Solano and win a pitcher of beer. (See Bug Squad blog) It's all part of his scientific research long-term studies of butterfly life cycles and climate change.
Meanwhile, we see the cabbage white butterfly fluttering around the garden throughout most of the year, stopping for a little nectar here, a little nectar there.
She still reminds us of Cinderella, with a long flowing gown. Sometimes she looks a little ragged when a predator snatches part of her gown. But her magic never seems to end.
