It's not spring until you see honey bees, carpenter bees and butterflies on Tidy Tips.
That would be Layia platyglossa, a wildflower native to southern California. Its common name is "Tidy Tips" or "Coastal Tidy Tips." It's a daisylike flower with yellow petals tipped in white, thus the name. It's a member of the aster family.
A flower bed in the center of the UC Davis campus (near the Science LaboratoriesBuilding) boasts an intermingling of the yellow-and-white Tidy Tips and sky-blue Desert Blue Bells (Phacelia campanularia).
Insects think so, too. On any given day you'll see honey bees, carpenter bees, butterflies and lacewings holding family reunions.

Blue merle mini-Australian shepherds have one.
So do honey bees.
What? A tongue.
For a puppy, the tongue can symbolize pure happiness. For a worker honey bee: a solid work ethic.
It's easy to take a photo of a happy puppy with her tongue hanging out, but not so easy to capture an image of a honey bee nectaring a flower--unless you have a macro lens, a quick trigger finger and a state of endurance called patience.
To be technically correct, entomologists refer to the honey bee "tongue" as "mouthparts." That would be the tubelike organ that enables them to nectar flowers and serve as nursemaids and undertakers and the like.
"The mouthparts of bees are of a chewing and lapping type," they write. 'Lapping is a mode of feeding in which liquid or semi-liquid food adhering to a protrusible organ, or 'tongue,' is transferred from substrate to mouth. in the honey bee, Apis mellifera (Hymenoptera Apidae), the elongate and fused labial glossae form a hairy tongue, which is surrounded by the maxillary galeae and the labial palps to form a tubular proboscis containing a food canal. In feeding, the tongue is dipped into the nectar or honey, which adheres to the hairs, and then is retracted so that adhering liquid is carried into the space between the galeae and labial palps. This back-and-forth glossal movement occurs repeatedly. Movement of liquid to the mouth apparently results from the action of the cibarial pump, facilitated by each retraction of the tongue pushing liquid up the food canal."
Wait! There's more.
"The maxillary laciniae and palps are rudimentary and the paraglossae embrace the base of the tongue, directing salvia from the dorsal salivary orifice around into a ventral channel from whence it is transported to the flabellum, a small lobe at the glossal tip; saliva may dissolve solid or semi-solid sugar. The sclerotized, spoon-shaped mandibles lie at the base of the proboscis and have a variety of functions, including the manipulation of wax and plant resins for nest construction, the feeding of larvae and the queen, grooming, fighting and the removal of nest debris including dead bees.
And you thought the mouthparts of a bee were simple? Not at all.

Industrious honey bee
Scottish poet Robert Burns (1759-1796) lamented in his poem “To a Mouse” (1786) that “The best laid plans of mice and men often go awry.”
He had just plowed into a mouse nest on his farm. The loss of life disturbed him.
Today folks have only to hear "best laid plans" and know about the "awry" or "astray" part..
Friday we were out looking for bumble bees (Plan A).
A brilliant pink shrub,
But the honey bees were all over it.
From Plan A to Plan Bee.

UC Davis Cooperative Extension apiculturist Eric Mussen, a member of the UC Davis Department of Entomology faculty for 32 years, says this looks like a challenging year for almond growers.
There's this water problem. Think "drought."
There's this honey bee crisis. Think "bee health" and "declining bee population."
Then there's these increased production costs. Think "tanked economy."
Christine Souza, assistant editor of Ag Alert, published by the California Farm Bureau Federation, wrote an excellent article in the Jan. 28th edition about the problems almond growers and beekeepers alike are facing.
Headlined "Challenges Face Almond Growers and Beekeepers," the article began:
A reduction in almond prices, limited water availability, increased production costs and the declining health of bees may all influence what happens during this year's almond bloom, impacting both almond growers and beekeepers.
Speaking at the Almond Board of California annual meeting last month, board member Dan Cummings warned his audience that this spring could be "dicey" for almond growers and beekeepers alike.
"Bees are competing for almond growers' money the same as water, fertilizer, fuel and all of our other inputs, at a time when the price of almonds has dropped. So we will be rationalizing where we go with our bees," said Cummings, who farms almonds in Chico and is co-owner of a full-service beekeeping operation. "We will be fallowing some other crops to direct water to almonds and perhaps abandoning almond orchards."
As a result, he said he believes many growers may reduce the amount of honeybee colonies that they place into the orchards for pollination during bloom, to save money.
And all this is happening right now. We saw the first almond blossoms this week in Yolo and Solano counties, a sure sign that spring can't be far behind.
Mussen told Souza that beekeepers are most concerned about the health of their bees, "whether they operate one colony in the backyard or thousands of colonies throughout the country."
"Money is important," Mussen told her, "because it costs nearly $150 to keep a commercial colony alive and productive over a year. Without that income the bees would be lost and the beekeeper would be out of business."
Get ready for the bumpy ride. Take a deep breath. And, as the bumpersticker says: Get in, sit down, and hold on tight.
This may be like Disneyland's Big Thunder rollercoaster that twists through mine shafts, bat caves and caverns.
And watch for the falling rocks.
Honey bee and almond blossom
Right out of Champaign, Ill., comes a research story about honey bees on coke.
University of Illinois entomology and neuroscience professor Gene Robinson and his colleagues have found that honey bees on cocaine dance more.
"In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate," wrote Diana Yates, life sciences writer at the University of Illinois at Urbana-Champaign in a Dec. 23 press release.
"Normally, foraging honey bees alert their comrades to potential food sources only when they've found high quality nectar or pollen, and only when the hive is in need," she wrote. "They do this by performing a dance, called a 'round' or 'waggle' dance, on a specialized 'dance floor' in the hive. The dance gives specific instructions that help the other bees find the food.
"Foraging honey bees on cocaine are more likely to dance, regardless of the quality of the food they've found or the status of the hive, the authors of the study report."
Scientists, led by Robinson, dabbed a low dose of cocaine on the bees' backs before they went out foraging. The Journal of Experimental Biology published the findings this month. Robinson, who calls the bee dance "one of the seven wonders of the animal behavior world," said the research also supports the idea that in certain circumstances, honey bees, like humans, are motivated by feelings of reward.
"Cocaine – a chemical used by the coca plant to defend itself from leaf-eating insects – interferes with octopamine transit in insect brains and has undeniable effects on reward systems in mammals, including humans. It does this by influencing the chemically related dopamine system," Yates wrote.
"Dopamine," she explained, "plays a role in the human ability to predict and respond to pleasure or reward. It is also important to motor function and modulates many other functions, including cognition, sleep, mood, attention and learning."
Well, when you consider the powerful effect of cocaine on humans, the bee research isn't all that surprising.
But this is NOT the reason for colony collapse disorder (CCD), in which bees mysteriously abandon the hive, leaving behind the immature bees and stored food.
Just wait--the same folks who attribute CCD to cell phone disturbance may now connect CCD with cocaine--and maintain that CCD actually stands for Co-Caine Disturbance.
Can't you just see it?
- Crack users will have another excuse when they're stopped by law enforcement. "This is for my bees, officer!"
- The number of beekeepers will increase ten-fold.
- Apiculture majors will rise high in the nation's entomology departments.
- Late-night shows will crack jokes about the the new bee buzz.
- "Making a beeline" will be linked with a line of coke.
And, Crystal Boyd's happiness comment will take on new meaning:
"Work like you don't need money,
Love like you've never been hurt,
And dance like no one's watching."
