Our buddy, the resident praying mantis, appears to be in perfect form.
Crouched beneath the Mexican sunflower (Tithonia), he glistens in the early morning light, as honey bees, long-horned bees, Gulf Fritillary butterflies and fiery skippers search for food. The flower is his beach umbrella, colorfully shading him but also stealthily hiding him.
Finally, he makes his move. He slips up and over the petals and perches on the head of the blossom. As he does, he swivels his head 180 degrees, checking out the photographer and the camera. No predator, no problem, he apparently decides. He assumes the position, folding his spiked forelegs.
A fiery skipper (Hylephila phyleus) floats by, almost touching down next to him. The praying mantis leaps, just as the startled butterfly spins away. A near miss.
A Gulf Fritillary butterfly (Agraulis vanillae) flutters by in his air space, unaware of the "no fly zone." The mantis lurches forward as the butterfly soars. A wide miss.
Praying Mantis: 0.
Sometime a miss is as good as smile.

When you're trying to rear Gulf Fritillary butterflies (Agraulis vanillae), expect the expected: predators.
It doesn't take long for European paper wasps (Polistes dominula) to find the butterfly's host plant, the passionflower vine (Passsiflora) and prey. We've seen the wasps, with their long hind legs dangling, follow the butterflies as they flit from tendrils to leaves to lay their eggs. The wasps grab the tiny yellow eggs and squirming caterpillars and rip into chrysalids.
They'll attack adult butterflies, too, especially the crippled ones.
Then off they fly with bits of food--protein--for their colony. Wasps are carnivores (unlike their cousins, the honey bees, which are vegetarians).
The European paper wasp, so named because of its European origin, is relatively new to the United States. Scientists tell us that the P. dominula was not recorded in North America until 1981. P. dominula was first discovered in the United States in the late 1970s near Boston, Mass. This invasive species has since spread rapidly across the country. Entomologists worry that it is displacing the native species of Polistes wasps.
Have you ever seen these wasps attack other insects? Butterflies?
Last Sunday we were watching a crippled butterfly (no doubt crippled by a predator such as a bird or praying mantis) clinging to a Passiflora leaf as males tried unsuccessfully to mate with her. Eventually, the males all fluttered away and a European paper wasp patrolling the area zeroed in for the attack.
Like a hungry lion singling out a crippled gazelle from a stampeding herd, the European paper wasp knew just what to do.

"Wow! Oh, wow!"
That's what people usually say when they encounter dozens of reddish-orange butterflies at a home on the 1500 block of Claremont Drive in Davis, Calif. The home is behind the Nugget Market on East Covell Boulevard, but the real gold mine, the mother lode, is that Claremont Drive fenceline of passionflower vines.
The passionflower vine (Passiflora) is the host plant for the Gulf Fritillary (Agraulis vanillae) of the family Nymphalidae and subfamily Heliconiinae. Homeowner Christina Cogdell, professor of architectural and design history in the UC Davis Department of Design, planted the vine several years ago.
Today it's a butterfly fandango.
You'll see butterflies mating. You'll see females laying tiny yellow eggs on the tendrils and leaves. You'll see caterpillars munching on the leaves. You'll see chrysalids dangling from the thin green stems. And then--voila!--newly emerged adults ready to start the life cycle all over again.
Cogdell generously donated some of her caterpillars for a Bohart Museum of Entomology open house last year. The 'cats were a big hit.
Noted butterfly expert Art Shapiro, professor of evolution and ecology at UC Davis who monitors the butterfly populations of Central California and posts the information on his website, has long admired the established population on Claremont Drive, as has naturalist Greg Kareofelas, a volunteer at the Bohart Museum and an avid butterfly aficionado.
Shapiro will tell you that the Gulf Frits first appeared in California in the 1870s in the vicinity of San Diego. In the early 1970s, they were considered extinct in the Sacramento-Davis area, but began making a comeback in 2000. The showy butterfly “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.”
Yes, recolonizing and doing well.
Today Cogdell pointed out a newly emerged Gulf Frit hanging onto its empty chrysalid. Female? Probably. We watched the Grand Little Lady unfold her wings and greet a number of ruggedly handsome males (and some raggedly handsome males, the work of predators). Then she took off, trailed by a fluttering line of males.
Christina Cogdell's Claremont home (note the alliteration!) will soon be for sale (for inquiring minds or lepitopterists who want to know, she's listed it with Claire Black-Slotton, First Street Realty). The professor's home is unique in that it's an architecturally unique urban "farm" home but it's also unique in that it comes complete with a treasure trove of butterflies. A veritable lepidopterist landmark.
If holidays ads can say "Batteries not included," maybe this home listing should say "Butterflies included."
We thought of that today as 50 butterflies gracefully fluttered around us.
Wow! Oh, wow!

If you have Mexican sunflowers (genus Tithonia) in your garden, you can expect a diversity of insects--and not just honey bees.
Lately we've been photographing all the insects that visit the Tithonia in our bee garden.
They include butterflies (including monarchs, Gulf Fritillaries, skippers and cabbage whites) bumble bees (Bombus vosnesenskii and Bombus fervides, formerly known as Bombus californicus), sweat bees, leafcutter bees, long-horned bees, praying mantids, honey bees, carpenter bees, and yes, flies (green bottle fly).
The Mexican sunflower, an annual in the sunflower family, Asteraceae, originates from Mexico and Central America. What's good about the Tithonia--besides its sizzling color and its ability to attract a diversity of insects--is that it's drought-tolerant. That's especially important as we thirsty Californians endure our worst-ever drought.
We grew our Mexican sunflower (Tithonia rotundifolia) from seed, and it should bloom all summer. Already it's reaching NBA basketball-stature--topping seven feet in height.
We may have to set up a orchard ladder in our bee garden on our next photo shoot!

There's a good reason why lepidopterists call the Gulf Fritillary (Agraulis vanillae) "showy."
Its bright orange-red wings, spangled iridescent silver on the underside, and a four-inch wingspan all point to "showy."
The Gulf Frit is a tropical and subtropical butterfly with a range that extends from the southern United States all the way to central Argentina. Back in September of 2009, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, excitedly announced the re-appearance of the Gulf Frit the Sacramento metropolitan area after a four-decade absence, and in the Davis area after a 30-year absence.
Yes, the Gulf Frits are back. Thankfully, they've returned to creating a nursery of sorts on our passionflower vine and their host plant (Passiflora). The eggs, caterpillars, chrysalids and adults are a delight to see.
However, the cycle of life is in full force in our bee garden. The hawks are eating the scrub jays; the scrub jays are eating the bees; and the bees are just trying to mind their own "bee business" by collecting pollen and nectar for their colonies. Always opportunists, the jays nesting in our trees are also targeting the butterflies and caterpillars. (So, too, are such predators as spiders and praying mantids.)
Today we captured several images of a Gulf Frit in flight. If you look closely, you'll see that part of her wing is missing.
That was a close one!
