Gulf Fritillaries in November?
Gulf Fritillaries (Agraulis vanillae) are still active here in Solano County, on those warm, sunny afternoons that defy the season.
They're still hanging around their host plant, Passiflora (passionflower vine), "looking for love" (thank you, Johnny Lee). And in all the RIGHT places.
The orange-reddish butterfly, with its silver-spangled underwings, was introduced into southern California in the 19th century, in the vicinity of San Diego in the 1870s, according to butterfly guru Art Shapiro, UC Davis distinguished professor of evolution an ecology. It was first recorded in the Bay Area before 1908. "It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since." Once prevalent in the Sacramento area in the 1960s, it "seems to have died out by the early 1970s," he says. Then in 2009, it began making a comeback in the Sacramento area.
In our pollinator garden, the Gulf Frits usually skeletonize the plant. They eat the leaves, flowers, the fruit, and then start in on the bark.
Not so this year. What's different? More predators, including California scrub jays, wasps and a resident praying mantis.
The resident mantis perished a month after depositing her egg case. The wasps vanished. And the California scrub jays, eyed by circling hawks, are nowhere to be seen.
Just the Gulf Fritillaries--their eggs, caterpillars, chrysalids and adults--remain.
Gulf Fritillaries in November? Yes.
Thanksgiving isn't about selecting the largest turkey in the store, engaging in road rage or aisle anger, or preparing for the Black Friday sales.
Thanksgiving is all about sharing--sharing gratitude, love and a meal.
UC Davis psychology professor Robert Emmons, a leading scientific expert on gratitude, says that a growing body of research confirms that an ounce of gratitude is worth a pound of cure.
A feature story posted on the UC Davis Medical Center relates that practicing gratitude can have dramatic and lasting effects in a person's life. Says Emmons: "It can lower blood pressure, improve immune function and facilitate more efficient sleep. Gratitude reduces lifetime risk for depression, anxiety and substance abuse disorders, and is a key resiliency factor in the prevention of suicide."
Practicing gratitude also affects behavior, he says. The UC Davis article points out that studies have shown that "grateful people engage in more exercise, have better dietary behaviors, are less likely to smoke and abuse alcohol, and have higher rates of medication adherence – factors that translate into a healthier and happier life."
Emmons' expertise on gratitude resulted in a $5.6 million grant from the John Templeton Foundation to explore the subject.
In the insect world, what better day to post an image of a Gulf Fritillary butterfly, Agraulis vanillae, sharing the nectar of a passionflower (Passiflora) with three honey bees?
Table for four, please.
It's not often you see "passion on passion."
You often see the males patrolling the vine and the females laying eggs on the leaves.
But have you ever seen one foraging on a blossom?
On sunny days in Vacaville, we're seeing it happen more and more.
The brilliant orange butterfly with the silver-spangled wings is one spectacular butterfly. Together the passion butterfly and the passionflower live up to their names.
Those passion flowers (Passiflora) are insect magnets.
One minute you'll see a praying mantis on a blossom. The next minute, a Gulf Fritillary, Agraulis vanillae. And the next morning, the blossom is an arthropod magnet--the beginnings of a spider web.
Passiflora is the host plant of the Gulf Fritillary, a spectacular orange butterfly with silver-spangled underwings. The Gulf Frit lays its eggs only on Passiflora.
The Gulf Frits know where the Passiflora is. Their predators know where the butterflies are.
The female mantis, Mantis religiosa (below), didn't snag the butterfly. But it did grab and munch on a few Gulf Frit caterpillars.
Ever critter eats in the garden.
Happy Labor Day!
And what an appropriate time to post an image of a Gulf Fritillary, Agraulis vanillae, depositing an egg!
The females lay their eggs on the tendrils and leaves of the butterfly's host plant, the passionflower vine (Passiflora) but we've seen them depositing eggs on nearby fences where the vines climb.
Butterfly guru Art Shapiro, distinguished professor of evolution and ecology, says the Gulf Frit was introduced into southern California in the 19th century, in the vicinity of San Diego in the 1870s. It was first recorded in the Bay Area before 1908. "It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since." Once prevalent in the Sacramento area in the 1960s, it "seems to have died out by the early 1970s," he said. Then in 2009, it began making a comeback in the Sacramento area."
It is a dazzling butterfly, what with its brilliant orange wings and spectacular silver-spangled underwings.
The Gulf Frit, also called the "passion butterfly," is usually quite skittish--except this one wasn't. We captured this image on Labor Day weekend in Vacaville, Calif., with a short macro lens--60mm--mounted on a Nikon D500.
She didn't seem to mind.
