Neophasia menapia – Pine White Butterfly
It was breezy earlier this afternoon when I spotted this beauty feeding on my daisies. This is a Neophasia menapia – or the Pine White Butterfly. I’ve been worried since we’ve put up deer fencing that the butterflies wouldn’t be able to find their way through the fence into my flower garden, but I shouldn’t have worried. The butterflies ever-so-gracefully float over the top.
I’m sure the butterflies and other pollinators appreciate that my daisies aren’t headless amputees this year, courtesy of our resident deer who now can only gaze at them. It’s hard to understand why the deer would even want to eat those flowers because they’re kind of stinky. To my nose, they smell a bit of cat urine. Lots of insects seem to like those sorts of smells though. These daisies can stay outside. I won’t be displaying them in a vase on my dining table.
The Pine White Butterfly larvae feed on Ponderosa Pine and Douglas fir. Adults emerge typically between the months of July and October. Look for little green eggs on the needles of pines and firs sometime beginning in October. The eggs will overwinter and hatch sometime in June the following summer, coinciding with the emergence of new foliage on the trees. Larvae typically only feed on old needles, but can become a “pest” when they feed on the new needles and/or population levels are high and the tree is repeatedly defoliated. Natural controls help keep caterpillar populations balanced. Larvae pupate in late July for about 15-20 days before emerging as adults to begin a new cycle.
