What's wrong with this photo?
A honey bee is nectaring a lavender, right?
But if you look closely, you'll see a Varroa mite--a parasite--attached to her.
Varroa mites, considered the No. 1 pest in the honey bee industry, are linked to colony collapse disorder, a mysterious phenomenon characterized by adult bees abandoning the hive, leaving behind food stores and the brood.
Varroa mites are so common that it's rare to find a hive without them.
Female mites reproduce inside brood cells in the hive. Mites suck the bee blood or hemolymph; in doing so, they spread viruses, stunt the growth and cause deformities.
Within two years, they can destroy a colony.
Not a pleasant sight.

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.

It's a blue day for the honey bees.
The massive Northern California storm--one of our worst-ever storms and marked by heavy rains and equally strong winds--means that bees are clustering inside their hives.
No foraging today.
Just last Sunday we saw honey bees nectaring blue marguerite daisy (Felicia amelloides), a colorful member of the sunflower family (Asteraceae). A native of South Africa, the marguerite daisy blooms through October.
This bee was quite old (notice the lack of hair on her thorax).
Today she's inside.
Out of the rain.

Summer is fading and the temperatures are dropping, too.
You're more likely to see Vanessa.
That would be Vanessa annabella, one of the Painted Lady butterflies.
The West Coast Lady (Vanessa annabella), is seen more often in cool seasons, says UC Davis butterfly expert, Arthur Shapiro, professor of ecology and evolution.
The West Coast Lady is a member of the Brush-Footed Butterflies (Nymphalidae) and the subfamily, True Brushfoots.
On a recent trip to Tomales, we spotted the West Coast Lady and a honey bee sharing the same plant, a Salvia uliginosa (a tall sage that can reach six to seven feet).
The wings of the orange-brown butterfly and the transparent wings of the honey bee glowed in the sunlight as the insects nectared the sky-blue blossoms. The two have at least one thing in common: they love a good sage.
Shapiro, a lepidopterist extraordinaire, covers more than 130 species in his colorful book, Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions, published by the University of California Press. The guide also offers tips on gardening and photography.

Aware of Each Other
The honey bee nectaring the Penstemon, aka Beardtongue, in Tomales, Calif., didn't seem to mind my presence.
The amber-colored bee was foraging among the purple two-lipped flowers. The plant derives its name from what appears to be a "tongue" (staminode) poking from the "mouth" of the blossom.
It's an attractive flower--indeed, humans hold Penstemon festivals in Flagstaff, Ariz. and Holden, Utah--and the bees like it, too.
The little Marin County honey bee glanced at me and then began cleaning her tongue. Or, as emeritus professor and pollinator specialist Robbin Thorp of the University of California, Davis, said of the photo below: "Caught in the act of cleaning her tongue with the brushes of hairs on the inner sides of her forelegs."
"Even worker bees take time to groom," he said. "Vanity or just good maintenance?"
We like to think she was primping for the photo shoot.
