Unlike airplane pilots, honey bees don't file a flight plan.
They know where they're going because their sisters tell them with their waggle dances.
Pollen. Nectar. Propolis. All good.
Bees seem to really like the pollen on rock purslane (Calandrinia grandiflora). It's red, but they can't see red; red appears to them as black.
Gardeners who grow rock purslane (Calandrinia grandiflora) in their yards are accustomed to seeing bees gathering red pollen.
Beekeepers? When they open their hives and see all the different colors of pollen--including yellow, orange, pink, purple, white and red--do they know where the red might have come from?
Interestingly, last year a beekeeper in the Red Hook neighborhood of Brooklyn, N.Y., reported seeing red--red honey. Finally, she realized her bees had been sipping maraschino cherry juice from vats at a nearby maraschino cherry company and bringing red "nectar" back to the hives.
It didn't taste like honey. That's because it wasn't.
The New York Times noted: "A fellow beekeeper sent samples of the red substance that the bees were producing to an apiculturalist who works for New York State, and that expert, acting as a kind of forensic foodie, found the samples riddled with Red Dye No. 40, the same dye used in the maraschino cherry juice."
Bee can't see red but a lot of other folks did.

Gotta love those soldier beetles.
They're among the good guys in the garden because they eat aphids and other soft-bodied insects.
We've seen them on the lavender, on our nectarine tree and on our plum tree. Last weekend, a single soldier beetle (family Cantharidae) winged its way to our patch of rock purslane (Calandrina grandiflora).
It dropped down and sat on the bud of a rock purslane, looking for all the world like a frog on a lily pad or a toad on a toadstool or a king on his throne.
Or, maybe this soldier beetle was really a general surveying his troops.

Aren't syrphid flies grand?
Syrphid flies, aka hover flies or flower flies (family Syrphidae), are especially grand in a Calandrinia grandiflora, aka rock purslane.
Often mistaken for honey bees, these insects hover over flowers, wings spinning like helicopters, and then dart inside a blossom to feed on pollen and nectar.
We spotted a brightly colored syrphid on a rock purslane in our garden last Sunday. It appeared in no hurry to leave its host.
Is it true that this colorful fly is in the same order (Diptera) as the common housefly? It is.
Hover flies are found everywhere in the world except Antarctica. For a look at some of the species, check out BugGuide.Net. The site contributors are self-described naturalists "who enjoy learning about and sharing our observations of insects, spiders, and other related creatures."
Another great source is entomologist Robert Bugg's 25-page booklet, "Flower Flies (Syrphidae) and Other Biological Control Agents for Aphids in Vegetable Crops," published in May 2008 by the University of California, Division of Agriculture and Natural Resources (UC ANR).

A light rainstorm strikes the garden, pummeling and shredding some of the blossoms.
As the rain lets up, a honey bee buzzes into a rock purslane blossom for a sweet shot of nectar.
She is not alone.
If you look closely, you'll see three green aphids on an unopened blossom next to her.
There are, entomologists say, about 450 different species of aphids in California.
One specie found the rock purslane (Calandrinia grandiflora).
Score: Beneficial insect: 1. Destructive pests, 3.
Aphids and Honey Bee
When a sweat bee and a honey bee share the same flower, the size difference is quite distinct.
We took this photo of a honey bee on a rock purslane (Calandrinia grandiflora) blossom.
Above it stood a tiny female sweat bee (probably Halictus tripartitus, according to native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis).
Two bees. Two sizes. One blossom. One native. One non-native. The sweat bee is a native, and the honey bee was brought over here in the 1600s by the European colonists.
Speaking of honey bees, this is the first day to participate in TwitCause. The Häagen-Dazs brand is donating $1 per Tweet (up to $500 per day) today through Nov. 11 to support honey bee research at UC Davis.
Häagen-Dazs joined forces with ExperienceProject.com (EP), a San Francisco-based online community for sharing life experiences.
