Sex in the afternoon. On the passionflower vine.
That's what happened today on the Passiflora (see images below). Coming soon, more Gulf Fritillaries.
The Gulf Frit (Agraulis vanillae), an orangish-reddish butterfly of the family Nymphalidae, is as spectacular as it is showy. Its silver-spangled underwings absolutely glow in the sunlight.
However, much misinformation surrounds it.
A recent article in a Bay Area publication indicated that it's been around the Bay Area since the 1950s. It's actually been around much earlier than that. It was first documented in Southern California in 1870s, according to noted butterfly researcher Art Shapiro, professor of evolution and ecology at the University of California, Davis, who has been monitoring the butterflies of central California for four decades.
"It first appeared in the vicinity of San Diego in the 1870s,” he says. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro says it “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
Have you ever wondered why the scientific name of the species is vanillae? That was an error traced back to the illustrator. German-born naturalist and scientific illustrator Maria Sibylla Merian (1647-1717) knew butterflies--she reared them--but she took some artistic liberties when it came to horticulture.
Merian drew the Gulf Frit on a vanilla orchid, and scientists assumed that this was the host plant. Not so. Passiflora is the host plant. "Johannes Fabricius knew that the bug eats Passiflora and tried to rename it passiflorae," wrote Shapiro in a 2008 edition of the Journal of the Lepitoperists Society.
It never happened. That's why we call it Agraulis vanillae and not Agraulis passiflorae.
But it is nicknamed the "passion butterfly."

Strange weather we're having here in Central California.
After soaring into the 90s, the temperatures pushed again into the 80s today (Oct.21). The Gulf Fritillaries (Agraulis vanillae) are "making the most-est" of their host plant, passionflower vines. Blossoms keep popping up like so much popcorn. And the Gulf Frits are there to lay their eggs all over the plant, including the tendrils, leaves, stems and blossoms.
The showy reddish-orange butterfly with the silver-spangled wings is a favorite this time of year. It's sort of like a Halloween gift before Thanksgiving.
We remember when it vanished in the Sacramento-Davis area and was even considered extinct around here in the early 1970s.
Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, sounded the alarm back then. He knows its history well.
“It first appeared in the vicinity of San Diego in the 1870s,” he told us. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Since 2000, the Gulf Frit has been recolonizing again throughout the area. Thankfully!
The butterfly lays its eggs only on passionflower vines (genus Passiflora)--lots of eggs--so expect the caterpillars to skeletonize the plant. It's a good idea to offer some nearby nectar for the adults, too. Their favorites include the butterfly bush, Mexican sunflower (Tithonia) and lantana.
Let's see, fall began Sept. 23, and winter arrives Dec. 21.
For the Gulf Frits, it might as well be spring!

Privacy, please!
You're walking by a patch of lavender and Mexican sunflower (Tithonia) and you notice that two Gulf Fritillaries (Agraulis vanillae) are doing what birds 'n' bees 'n butterflies do.
Well, some folks call it "bug porn" and some call it a "two-for" images--two insects in one photo. But in this case, this was a "three-for" image. A honey bee nectaring on the nearby lavender photobombed my image and the mating pair, still attached, clumsily fluttered off in a four-wing attempt. Appropriately enough, they headed over to the pasionflower vine, their host plant
We recall butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, telling us several years ago that the showy reddish-orange butterfly is making a comeback in the Sacramento-Davis area. In the early 1970s, it was considered extinct in that area.
“It first appeared in the vicinity of San Diego in the 1870s,” he related in a previous Bug Squad blog. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro says it “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
One of the Gulf Frit's favorite nectar sources is lantana (genus Lantana, family Verbenaceae.) In our yard they also lean toward the lavender and Tithonia.
There, on appropriate occasions, they like a little privacy.

Sometimes you just can't win for losing.
This morning a newly emerged Gulf Fritillary butterfly (Agraulis vanillae) began drying its damp wings, preparing for flight. It had just emerged from its chrysalis. Soon it would be off to do what Gulf Frits do: leave its host plant, the passionflower vine, and find a mate.
It was not to be.
A cunning praying mantis, camouflaged as a green stem, snared it, grasping it in its spiked forelegs. Then it did one praying mantids do. It bit off its head and proceeded to eat it.
Quick and easy prey, for sure. But the mantis was not alone. A European paper wasp, seeking a little free protein to take back to her colony, got into the act, circling the struggling butterfly and taking quick bites.
The wasp carefully evaded the mantid's head and spiked forelegs.
If it it had not, this it would have been a two-course dinner. Butterfly first, wasp second.
Mouse Productions filmed a battle between a praying mantis and a wasp back in 2013. The mantis won. See YouTube video.

How can you hate a caterpillar and love a butterfly?
You can't.
Some gardeners so love their passionflower vine (Passiflora) that they squirm at the thought of a caterpillar munching it down to nothing.
But that's what caterpillars do. The Gulf Fritillary butterfly (Agraulis vanillae) lays its eggs on its host plant, the passionflower vine, the eggs develop into larvae or caterpillars, and the caterpillars into Gulf Frits.
Our passionflower vine--which we planted specifically for the Gulf Frits--is now a skeleton. The caterpillars ate all the leaves, the flowers and the stems. What was once a flourishing green plant looks like a criss-cross of brown sticks.
Comedian George Carlin supposedly said "The caterpillar does all the work but the butterfly gets all the publicity."
And architect-author-designer-inventor Richard Buckminster Fuller observed: "There is nothing in a caterpillar that tells you it's going to be a butterfly."
And someone named John Grey offered this poetic comment:
"And what's a butterfly? At best,
He's but a caterpillar, at rest."
So, it is. Take a look at the Gulf Frit caterpillar and then check out the Gulf Frit butterfly.
Yes, a hungry caterpillar turned into a magnificent butterfly.
How can you hate a caterpillar?
You can't.
