Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.
--Nathaniel Hawthorne

Maybe not "alight upon you," but stay long enough for you to admire it.

Such was the case today with the Mournful or Sad Dusky-Wing, Erynnis tristis (Hesperiidae).

UC Davis butterfly expert Arthur Shapiro, professor of evolution and ecology at the University of California, Davis, describes it as "Common below 2000, including the Sacramento Valley; the only Erynnis routinely found in cities. A strong flier but not a very dedicated puddler, it is multiple-brooded, from March to October. This is the only common Dusky-Wing with a white fringe (compare E. funeralis)."

Shapiro says the Mournful Dusky-Wing visits tall blue verbena, yerba santa, California buckeye and a variety of garden flowers, including the butterfly bush (Buddleia davidii).

Today it was visiting lavender, both purple and white lavender. It lingered long enough to be admired.
