A monarch on the move...
When you see a monarch foraging on a flower, have you ever seen them--or photographed them--taking flight?
It's not your iconic image of monarch, but a few twists and turns, jumble of colors and jagged lines, and the monarch takes flight.
Scenario: a male monarch nectaring on Sept. 4 on a Mexican sunflower, Tithonia rotundifola, in a Vacaville pollinator garden.
He decides it's time to depart--maybe because he's had his fill of nectar, or maybe because male longhorned bees are becoming increasingly territorial, or maybe just because....

Sometimes there's a method to our madness, or madness to our method.
Take the silver-spangled, orange-reddish butterfly, the Gulf Fritilllary (Agraulis vanillae).
We spotted a female dive-bombing her host plant, the passionflower vine (Passiflora) in our pollinator garden in Vacaville. She circled, dipped, soared, and dipped again. She flew upside down, and right side up.
Ah, a photographic challenge!
We managed to catch her in flight, using a Nikon Z7 mirrorless camera mounted with a 105mm Nikon lens. We set the shutter speed at 1/3200 of a second to freeze the action. Other settings: f-stop of 5.6, and ISO of 250.
Then we focused on the area where we thought she'd be. Look where she's going, not where she's been!
And what a gorgeous butterfly and what a beautiful ballet! Finally, she laid some eggs on the tendrils and leaves and vanished.
Butterfly guru Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, says the Gulf Frit was introduced into southern California in the 19th century, and was first recorded in the Bay Area before 1908. Once prevalent in the Sacramento area in the 1960s, it "seems to have died out by the early 1970s."
Then in 2009, the Gulf Frits began making a comeback in the Sacramento area.
This year the sightings are rather slow, but one butterfly ballet--just one--brings back the wonder of it all.

Friday, Feb. 11 seemed like a glorious spring day. Almond trees at the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis burst into bloom.
Early birds...err...early bees...began foraging among the blossoms.
A faux spring.
Then the rains came. Almond pollination and spring buildup in the hives will have to wait until the rain stops and the cold weather subsides.
The flight of the honey bee? Stilled.
