Whenever folks post photos of praying mantids, their readers expect to see prey.
You know, the hapless bee or butterfly that made the fatal mistake of getting too close to those spiked forelegs.
This praying mantis (below) appeared to have been a hapless victim of another predator. It, still however, kept that praying mantis pose as it tried to find prey on a blanketflower (Gaillardia). And it still rotated its head 180 degrees.
Praying mantis belong to the order, Mantodea, which includes more than 2400 species and about 430 genera in 15 families, according to Wikipedia.
"They are distributed worldwide in temperate and tropical habitats. Most of the species are in the family Mantidae," Wikipedia tells us. "Females sometimes practice sexual cannibalism, eating their mate after, or occasionally decapitating the male just before mating."
Did you know that the closest relatives of mantids are termites and cockroaches (Blattodea)? And that they are sometimes "confused with stick insects (Phasmatodea) and other elongated insects such as grasshoppers (Orthoptera), or other insects with raptorial forelegs such as mantisflies (Mantispidae)?" Check out Wikipedia's entry for praying mantids.
Praying mantids live about a year. This one lived about five hours before it expired.
But not before it gave a honey bee the fright of her life.

The hummingbirds seemed apprehensive.
They'd fly to the feeder, stop in mid-air, and turn back.
What was keeping them from the feeder?
A closer look revealed what the casual observer wouldn't notice: a praying mantis.
Was the mantis a predator or the prey? Hummingbirds eat insects, and the larger mantids eat hummingbirds.
We waited to see what would happen next.
A hummer opted to take a drink. The praying mantis, sprawled out on the feeder in a position we've never seen before, didn't move.
It later moved to another spot on the feeder.
The next morning, no mantis. Gone.
Maybe it moved to another location. Or maybe another predator nailed it.
Meanwhile, check out a photo published in National Geographic that shows a praying mantis grasping a hummer. It's not for the squeamish.
And YouTube shows numerous videos of mantids attacking hummers. Watch this video of multiple hummers trying to dodge a praying mantis.

There is such a thing as a free lunch. And a free breakfast. And a free dinner.
And a free snack.
That is, if you're a freeloader fly.
If you've ever watched a spider snare a bee or other insect in its web, and wrap it like a fit-to-be-tied holiday present, you've probably seen tiny little freeloader flies dining on the prey.
They are so tiny--usually 1 to 3 mm in length--that it takes a keen eye to spot them if they're not moving. The eyes are often red though "this need not be obvious because many species of the flies are small and dusky."
The close-up below is a hand-held photo taken with a Canon EOS 7D with a MPE-65mm lens.
Freeloader flies belong to the family Milichiidae. The close-up below may be in the genus Desmometopa, but it's difficult to tell by the image, says Martin Hauser, senior insect biosystematist with the Plant Pest Diagnostics, California Department of Food and Agriculture.
As it turned out, the spider dropped its prey and the freeloaders flies didn't have to leave the table.

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.

That's not to say you'll see beneficial insects doing their thing—but you might.
The event, a walk and talk, is “Scouting Out the Hedgerows on the DH Long Farm,” set from 10 a.m. to noon at 8304 County Road 91B, Zamora. Coffee and snacks will be available at 9:45.
The workshop, free and open to the public, is sponsored by the UC Agriculture and Natural Resources, the Department of Pesticide Regulation (DPR), Solano Resource Conservation District (RCD), Colusa County RCD, and the Yolo County RCD. Attendees are asked to wear "good walking shoes and a hat" and bring water.
The event begins at 10 with a welcome by Laurel Sellers, UCCE project assistant, Yolo County, who will provide a DPR grant project update.
Next to speak will be John Anderson of Hedgerow Farms, Winters, at 10:10. His topic is “Land of Milkweed and Honey: A Walk Into Beneficial Insect Habitat.”
Anderson will be followed at 10:35 by Sellers speaking on “Rodent Activity and Hedgerows: What's the Correlation?” Sellers is a master's degree candidate in international agricultural development, UC Davis.
Then at 10:55, Kristina Wolf, a doctoral candidate in entomology at UC Davis, will cover “Raptors, Rodents and Reptiles, What's in Restored Grasslands?”
Rachael Long, UC Cooperative Extension Farm Advisor, Yolo County, will offer her insights on “Establishing Hedgerows: Protecting Crops with Insect Predators and Parasitoids” at 11:15.
Following Long's talk, Kelly Garbach of Loyola University, Chicago, will share “Hedgerow Survey Highlights.” A summary and audience review will follow.
