Especially when it nectars from catmint (Nepeta) in the early evening, as the sun drops low in the horizon.
Butterfly expert Art Shapiro, professor of ecology and evolution at the University of California, Davis, says the species was introduced in southern Canada in the 1850s. "The great lepidopterist Samuel H. Scudder traced its spread, but was unable to resolve the history on the West Coast," he writes on the website, Art's Butterfly World.
"It was not in San Francisco in the early 1880s, but was abundant by the time of the earthquake (1906)."
Just look at it now. It's everywhere. In fact, every year Shapiro sponsors a contest to see who can find the first cabbage white of the year in the Davis-Sacramento area.
He usually wins.
But last week, for the first time, we spotted a male Acmon Blue, Plebejus acmon, as identified by noted butterfly expert Art Shapiro, professor of evolution and ecology at UC Davis.
With its wings spread, the blue is dazzling.
Actor William Hurt starred in a 2004 movie, "The Blue Butterfly," but this Acmon Blue butterfly stars in its own galaxy.
Tame that tiger.
Wilton beekeeper Brian Fishback, president of the Sacramento Area Beekeepers' Association, stopped Friday at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, and a friendly Western tiger swallowtail greeted him.
At least, it seemed quite friendly.
Fishback and Laidlaw staff research associate Elizabeth “Liz” Frost paused to watch the butterfly (Papilio rutulus) glide in and out of the flower garden in front of the facility.
Fishback held out his hand. The butterfly obliged and touched down for just a moment.
This year is a good year for Western tiger swallowtails.
There’s an outbreak--or an elevated population--in the area, says noted butterfly expert Arthur Shapiro, professor of evolution and ecology at UC Davis. “I’ve seen as many as 11 a day in Davis recently, and the outbreak ranges from as far west as Vallejo and as far east as Reno.”
This is the second year for elevated populations of the tiger, Shapiro says. The epicenter seems to be Davis.The colorful butterfly visits a variety of hosts, including California yerba santa, milkweed, lilies, lilacs, coyote mint, California buckeye, sycamore, privet and sweet gum.
It doesn't mind being around the 6 million honey bees (from 110 hives) in the apiary at the Laidlaw facility, either.

Sip of Nectar
Call it the "Mournful Dusky-Wing" or the "Sad Dusky-Wing."
Call it what you will, but the Erynnis tristis, a member of the skipper butterfly family (Hesperiidae), is neither mournful nor sad when it's nectaring lavender.
The skipper, distinguishable from other dusky wings by its white fringe, is a frequent floral visitor.
As a caterpillar, its host is oak, including Valley Oak and Cork Oak, says UC Davis butterfly expert Art Shapiro, professor of evolution and ecology.
Compared with other butterflies, including the Western Tiger Swallowtail, "E. T." is not the most beautiful of butterflies.
It doesn't stand out in the crowd. But it does stand out in the lavender.
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."
