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.
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.
It's Thursday afternoon, Aug. 20, and it seems like a good time to run a photo of a Gulf Fritilliary.
Because it just is.
It is a joy to see, especially when joy seems elusive as out-of-control wildfires ravage California.
As butterfly guru Art Shapiro, distinguished professor of evolution and ecology at UC Davis says about Agraulis vanillae on his website:
"This dazzling bit of the New World Tropics was introduced into southern California in the 19th Century--we don't know how-- and was first recorded in the Bay Area before 1908, though it seems to have become established there only in the 1950s. It can be quite common in the East and South Bay --particularly in Berkeley-- and has been found breeding spontaneously as far inland as Fairfield where, however, it is not established. There are scattered records in the Central Valley and even up to Folsom, perhaps resulting from people breeding the species for amusement or to release at social occasions. According to Hal Michael, who grew up in South Sacramento, this species bred there in abundance on garden Passiflora in the early 1960s. It seems to have died out by the early 1970s, however. Intolerant of hard freezes, it still managed to survive the record cold snap of 1990 that largely exterminated the Buckeye regionally!"
Its host plant: genus Passiflora or passion flower vine.
"In the Bay Area this species can be seen flying any day of the year, if it is warm and sunny enough," says Shapiro, who has been monitoring the butterfly populations of Central California since 1972 and posts the information on his website.
And if it's "warm and sunny enough," and you're growing Mexican sunflower (genus Tithonia rotundifolia), be sure to capture an image of a dazzling Gulf Fritillary nectaring on that equally dazzling blossom.
Both are a joy to see.
Fifty shades of orange—with a touch of silver.
The bridal couple on the pomegranate tree wore orange and silver to celebrate their honeymoon.
The bride may have blushed. I don't know. Did she? Don't all brides blush?
The groom, in true form, looked quite dapper and dashing.
So there they were. The two of them. The blushing bride and the quite dapper-and-dashing groom.
They didn't invite me to their wedding. I was an uninvited guest, the only guest. So I felt obliged to crash their wedding and capture some images.
Just happened to have a camera with a zoom macro lens slung on my shoulder.
Who can resist insect wedding photography? That's about the only wedding photography happening during the COVID-19 pandemic.
This couple? Gulf Fritillaries: Agraulis vanillae. (See UC Davis distinguished professor Art Shapiro's website to learn more about them).
We usually see Gulf Frits on their host plant, the passionflower vine (Passiflora), where the females lay their eggs. and the cycle of eggs-to-caterpillars-to-chrysalids-to-adults continues.
But something startled this pair and off they fluttered from the passionflower vine to the nearby pomegranate tree.
Ever seen the amazing macro photography of Alex Wild, curator of entomology at the University of Texas, Austin? He holds a doctorate in entomology from UC Davis, where he studied ant taxonomy and evolution with major professor Phil Ward. Wild also writes the incredible blog, Myrmecos: Little Things Matter, and teaches photography with colleagues at BugShot courses. He shoots Canon with an MPE-65mm lens.
On July 5, Alex Wild pinned this tweet:
"I'm pretty sure you didn't ask for this, but here's a gallery of insects having sex."
I'm pretty sure Alex Wild does not mince words.
Meanwhile, check out his "insect wedding photography" images!
