The Gulf Fritillary, Agraulis vanillae, and the Mexican sunflower, Tithonia rotundifola, seem made for one another.
Both are a showy orange. Both are show-stoppers. And both attract a photographer's eye.
Especially when a Gulf Frit flutters over a Tithonia on a warm sunny day in a Vacaville garden.
A shutter speed of 1/5000 of a second (Nikon D500 with a 200mm lens) stopped the action.
"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," writes butterfly guru Art Shapiro, UC Davis distinguished professor emeritus, on his website, Art's Butterfly World. "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."
Shapiro, who has monitored butterfly populations in Central California since 1972, continues: "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!"
"This butterfly has no native host plant in California and is entirely dependent on introduced species of the tropical genus Passiflora (Passion Flower, Passion Vine), including the common Maypop (P. incarnata) and P. X alatocaerulea. However, it will not eat all of the Passiflora in cultivation in California."
"In the Bay Area this species can be seen flying any day of the year, if it is warm and sunny enough."
On this day in Vacaville, it was indeed warm and sunny enough: 100 degrees.

Just a few more weeks of summer remain! As the weather begins to shift, you may need to adjust your landscaping practices to prevent and monitor for fall pests. The UC IPM Seasonal Landscape IPM Checklist is a monthly guide to help you avoid common pests of landscape plants.
Here are some general tips for the month of September to prevent pests and their damage in the garden and landscape. Visit the checklist online to see more pest management to-dos for your region.
- Monitor citrus plants for signs of pests such as Asian citrus psyllid or leafminers.
- Adjust irrigation to account for any change in weather and increased rainfall.
- Inspect apple, citrus and especially Prunus species (e.g., stone fruit) for bacterial blast, blight, and canker. Remove entire affected branches in the summer, making cuts several inches away in healthy wood.
- Check for aphids. Most established plants can tolerate aphid feeding. On small plants, knock aphids off with a strong stream of water or apply insecticidal oils and soaps to manage.
- Check for signs of powdery mildew on apple, crape myrtle, grape, rose, and stone fruits.
- Manage ants around landscapes and building foundations using insecticide baits and trunk barriers.
- Look for leaffooted bugs feeding on fruit and nuts such as almonds, pistachios, and pomegranates.

So here's this praying mantis, a female Mantis religiosa, tucked beneath a Mexican sunflower, Tithonia rotundifola, in a Vacaville garden.
She's as still as a stone, and you know how still stones are.
Along comes a honey bee, Apis mellifera. She's packing a load of orange pollen. She lands on the blossom and begins foraging.
She does not see the mantis, commonly known as "the European mantis."
The mantis sees her.
What happened?
Well, Ms. Bee continued to forage, oblivious to the predator and the pending danger, and then buzzed away.
Ms. Mantis remained as still as a stone.
And then, she, too, took flight...in the opposite direction.
No prayers answered today--for the mantis.

It's Labor Day, but honey bees aren't relaxing. They're out in force collecting nectar, pollen, water and propolis.
Ever seen them weighted down with huge pollen loads?
They seem to have "Herculean strength," don't you think? That's what Norman "Norm" Gary, emeritus professor of entomology at the University of California, Davis, writes in his book, Honey Bee Hobbyist: The Care and Keeping of Bees, considered the bible for hobby beekeepers.
"Ten pollen foraging trips a day is par for the typical pollen forager," Gary relates. "When pollen is abundant, a bee can gather a full load in as little as 10 minutes by visiting several dozen flowers...When all factors are favorable, bees from a strong colony can collect many thousands of loads a day. Incidentally, when.beekeepers describe their colonies as strong. they really mean populous--even though bees as individuals seem to have Herculean strength, flying with loads nearly as heavy as their body weight."
In an email, he wrote: "A worker honey bee weighs about 100 milligrams and are reported to be able to carry about 75 milligrams…approximately 75 percent of is body weight!"
Gary, now 90, served as a member of the UC Davis faculty from 1962-1994. He has kept bees for 75 years, starting at age 15.
As an aside, you may know him as not only a professor, scientist, musician, and author but one of the world's most incredible professional bee wranglers. He used to wear full-body bee suits and play the b-flat clarinet. (See Bug Squad blog of Nov. 30, 2016). He once trained bees to fly into his mouth to collect food from a small sponge saturated with his patented artificial nectar. He holds the Guinness World record (109 bees inside his closed mouth for 10 seconds) for the stunt.
Norm Gary knows bees.
