Yes, Virginia, there is such a thing as "red pollen."
Like people, pollen comes in many colors and all are beautiful. All.
The floral source determines the color of the pollen. Just as nectar is a carbohydrate source, pollen is a protein source. Honey bees need both to rear the brood.
One of my favorite bee images is a photo I took in my backyard of a honey bee sipping nectar from lavender. "What's that red stuff on her?" non-bee folks ask.
Pollen. Red pollen.
Bee folks question its origin. It's from the nearby rock purslane (Calandrinia grandiflora). This honey bee, after gathering protein from the rock purslane, buzzed over to the lavender for some carbo loading. A little fuel for her flight back to the hive.
Bees gather red pollen from many floral sources, including not only rock purslane--a succulent--but horse chestnut (Aesculus hippocastanum), snowdrop (Galanthus nivalis), pear (Pyrus communis), and henbit (Lamium amplexicaule).
When I see red pollen, I think of the beauty of a delicate flower transferred over to a hard-working bee. I don't think of the color's negative connotations: red tape, red-eye flight, red herring, and caught red-handed.
"Red pollen" is "Christmas red" or "holiday red."
Merry Christmas! Happy holidays! And the best of the new year!

If you want to take photos of honey bees in flight, do so early in the morning. They don't move as fast and the lighting is to die for.
This morning we stepped out in our yard, steaming coffee in hand, and watched the honey bees foraging among the lavender blossoms. Against the backdrop of red pomegranate blossoms and spring green leaves, they crawled up and down the lavender and then took off for the next blossom.
So smoothly. So effortlessly. So tirelessly.
You don't always have to stop the action with a flash. We took this with a Nikon D700 with a 105mm macro lens. No flash. We set the aperture (f-stop) at 8, the shutter speed at 1/800th of a second, and the ISO at 800.
The blurring of the wings added to the feeling of speed.
Indeed, the honey bees seem a little more frantic now as they rush to bring back nectar, pollen, propolis and water to the hive. With the queen bee laying about 2000 eggs a day now, everyone has to pitch in.
Just call this "The Lavender Blossom Special."

Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology faculty, emphasizes that if you're planting flowers to attract bees--and you should--be sure to remember them in the fall--not just the spring and summer.
In the fall, food is scarce. In the spring and summer, food is abundant.
We're often asked for plant lists. UC Berkeley has an excellent site on urban bee gardens, and the Xerces Society for Invertebrate Conservation has a comprehensive list of what to plant in your area.
The blueprint for what's planted in the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, is online (21-page PDF). You can download it and see what's planted there.
Also see California native plants that bees visit on the Laidlaw website.
Another way to come up with what to plant is to visit your local nursery. Observe where the bees are.
A visit today to the Mostly Natives Nursery, Tomales (Marin County), showed the bees all over scores of plants, including lavender (below).
Follow the bees and you'll know what to plant.

Working the Lavender
Ladybugs, aka ladybeetles (family Coccinellidae), are best known for devouring aphids, those pesky little critters that suck plant juices.
But have you ever seen ladybugs gobbling ants?
There's a three-way predator-prey relationship here. When aphids pierce plant stems, they leave behind honeydew excretions. Ants scurry to the honeydew and quickly alert their buddies. Soon, you'll see a long trail of ants marching toward the honeydew.
Now enter the ladybug, which is attracted--quite nicely, thank you--to both aphids and ants.
This little beetle will feast on aphids and ants much like we humans chow down on popcorn and jelly beans at a movie.
In the photos below, unsuspecting ants climbed a lavender stalk, only to meet their demise.
If you look on You Tube, you'll see a video of an apparently famished ladybug chowing down ants. The background music of Queen's "We Will Rock You" adds the finishing touch.
Want to learn more about ants? Check out professor Phil Ward's website. He's a noted myrmecologist (one who studies the taxonomy, evolution, biogeography and behavior of ants) and a professor of entomology at the University of California, Davis.
One of his former graduate students, Alex Wild, has incredible insect photography on his website, appropriately named myrmecos.net.
We can learn a lot from insects, especially when a predator ambushes its prey.
An ambush, as defined by Wikipedia "is a long-established military tactic in which the aggressors (the ambushing force) use concealment to attack a passing enemy."
The crab spider is a perfect example of an insect that conceals itself in a flower and waits for an unsuspecting visitor.
The crab spider doesn't build a web to trap its prey. No, too much wasted energy. It capitalizes on concealment, the element of surprise, and the quick assault and rapid kill.
And then, a leisurely meal.
Crab spiders or Thomisidae family (order Araneae) resemble crabs in that they can move sideways or backward.
You rarely notice them.
Neither do their prey--until it's too late.
