It's a bug-eat-bug world out there.
Today we watched a syrphid fly, aka "hover fly" and "flower fly," circling a blanket flower (Gaillardia) and then touching down to sip a little nectar.
Syrphids are called "hover flies" for good reason. They "hover" over a blossom, helicoperlike. They're often mistaken for bees but to the trained eye, they really look nothing alike. Folks confuse them because both bees and syrphids are floral visitors and both are pollinators.
If it's a floral visitor, it must be a bee, right? Wrong.
Anyway, this syrphid touched down on the blossom to sip nectar, its wings glinting in the early morning sun. Finally, it spotted the danger, a jumping spider lurking on the other side. The crafty predator lunged. Missed!
When we returned a few minutes later, however, we saw the jumping spider beneath the petals, feasting on the syrphid.
Quickness is an attribute--whether you're a jumping spider or a syrphid.
If you want to learn more about flower flies, read entomologist Robert Bugg's "Flower Flies (Syrphidae) and Other Biological Control Agents for Aphids in Vegetable Crops" (Publication 8285, May 2008, University of California, Division of Agriculture and Natural Resources.)

Jumping spiders have to eat, but do they have to snag the bees?
Last weekend as we were checking the lavender patch in our yard, we noticed something partially hidden--and moving--on a post.
It was a jumping spider eating a honey bee. Later in the afternoon, the same jumping spider snared a sweat bee.
If you have flower patches in your yard--and you should, to attract the pollinators--you will also attract the predators.
Fortunately, they don't eat as much as Joey "Jaws" Chestnut of San Jose, the hot-dog eating champion of the world.

If you walk slowly into your garden or backyard, and observe your surroundings, you'll find them. A jumping spider perched on a rose leaf. A soldier beetle climbing out of a tulip. A syrphid fly, aka flower fly or hover fly, foraging on a poppy blossom.
The insects (and spiders!) are back. The springlike temperatures, accompanied by bursts of rain, mean that these tiny little critters are everywhere.
If you pop a macro lens on your single-lens reflex camera, or use the macro setting on your point-and-shoot camera, you'll get them. There's even a set of lenses (macro, wide-angle and telephoto) that magnetically attach to your I-phone camera.
Travelers say it's fun and educational to go to Africa on safari, but you can also go on a Bug Safari in your backyard. It won't cost nearly as much, you don't have to make reservations, you don't have to hire a tour guide, and you don't have to worry about a water buffalo charging you.
Or your credit card company charging you.

One left hungry. One didn't.
We watched a leafcutter bee (genus Megachile) foraging on a gold coin flower (Asteriscus maritimus 'Gold Coin') yesterday when suddenly danger lurked.
A jumping spider peered over the petals, its legs (aka "claws") extended in anticipation, the mark of a good hunter.
The jumping spider (family Salticidae), easily identified by four pairs of eyes, can jump several lengths of its body.
That's good enough to nail a leafcutter bee, but not this time.
Score: Leafcutter Bee 1, Jumping Spider, 0.
