What a treat to see the Western Tiger Swallowtail (Papilio rutullus) gliding into a patch of ookow (Dichelostemma congestum), also known as wild hyacinth.
A recent outing to Healdsburg, Sonoma County, found the tiger on the ookow.
The colors were perfect: the bright yellow butterfly bordered in black visiting the delicate purple flower with light yellow stamens.
Fortunately, the Western Tiger Swallowtail cooperated with the photographer by lingering in the flowers. He perched, wings open, then fluttered away.
Him? Yes. UC Davis butterfly expert Art Shapiro knows his butterflies.
He also knows his "hims" and "hers."
