Sometimes you don't think about the declining bee population when you see a pollen-dusted honey bee rolling around in a poppy blossom, but colony collapse disorder (CCD) is still with us.
Pollinator protection is a must.
That's why we were glad to see the U. S. House of Representatives yesterday pass HR 2997, the "Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act" for fiscal year 2010.
The vote was 266-160, and now the bill is off to the U.S. Senate for approval.
"Hastings Amendments Bee-Come Part of Ag Appropriations Bill--Provisions Increase Funds for Pollinator Protection," Van Arsdale wrote in his e-mail subject line, with a teaser message that said "bee-low and attached."
Basically, Hastings' amendments increase funding for research into pollinator decline and CCD.
"Congress must continue to secure the necessary funding to proactively address pollinator decline," Hastings said in a press release issued by his office. "The fact of the matter is that pollinators are responsible for vast portions of our food supply and exported crops, which makes their decline an urgent matter of economic and food security. Without an adequate supply of natural pollinators, many crops would require hand pollination, which would dramatically raise crop prices."
Yes, one-third of the American diet is pollinated by honey bees. In California alone, more than 100 crops depend on bee pollination services.
The tanked economy has us all scrambling to make ends meet, but it's scary to think what the loss of bees would do to our food supply.
Bee-cause that would be disastrous.
Two newly moulted insects in the Bohart Museum of Entomology at the University of California, Davis, look just like leaves.
But these “leaves” are made for walking.
These are camouflaged insects (Phyllium giganteum), commonly known as "walking leaves." They're green, wide, and flat.
“They’re hard to detect among the leaves,” said senior museum scientist Steve Heydon. “It’s surprising how long it takes visitors to find them.”
The insects, natives of Malaysia, dine on bramble, oak, eucalyptus, raspberry, rose, and red/yellow salmon berry.
They mimic leaves in the wind by swaying as they walk, Heydon said. Females can reach a length of 5 inches.
“We got them as nymphs,” Heydon said. “They grow very slowly, probably the slowest of all the insects we’ve ever had at the museum. It took nine months for them to moult and become adults, and they each did it within a day of each other.”
The insects, splotched with red, look like green autumn leaves turning color. “With insect camouflage, there’s never a perfect leaf,” Heydon said. “You see simulated damage.”
Lynn Kimsey, director of the Bohart Museum and UC Davis entomology professor, said she’s always craved walking leaves for the museum. “They are so incredibly bizarre-looking,” she said. “It’s amazing how this insect develops new skin when its abdomen is as flat as paper.”
The Bohart Museum of Entomology, founded in 1946 by the late Richard M. Bohart, former chair of the UC Davis Department of Entomology, is dedicated to teaching, research and service. The insect museum houses more than seven million specimens, the seventh largest insect collection in North America.
The museum also includes live insects such as Madagascar hissing cockroaches, walking sticks, and black widow spiders.
But for now, the walking leaves are the big attraction.
At the Bohart, you can actually "turn over a new leaf"--and it will be an insect.
Do you recognize the native bee that graces the cover of the current edition of California Agriculture, a peer-reviewed journal published by the UC Division of Agriculture and Natural Resources?
Yes, it's a carpenter bee. The spectacular photograph by Rollin Coville captures this native pollinator nectaring a mint flower in an urban
You've probably seen this insect in your own garden. It's about the size of a bumble bee with a decimel level that rivals rush-hour traffic.
The carpenter bee is just one of the native bees featured in the July-September edition.
UC Berkeley entomologist Gordon Frankie, a professor in the Department of Environmental Science, Policy and Management, wrote the lead article with several co-authors, including professor emeritus Robbin Thorp of the UC Davis Department of Entomology. (Thorp, a noted bumble bee expert, recently presented a Webinar at UC Davis on bumble bees.)

The photos drive home the point that not all bees are honey bees, and the bee we know as a honey bee is not a native. In fact, European colonists brought the honey bee (Apis mellifera) to North America
The journal article spotlights bee-pollinator research conducted over a three-year period in seven cities from northern to s
And now, more good news...
The national award-winning California Agriculture journal, edited by executive editor Janet White and managing editor Janet Byron, just reached a major milestone. Their newly launched Web site, two years in the making, offers the full text of nearly 6000 articles published over the past 63 years. Free access. Searchable, too. You’ll want to bookmark the link.
The military has its 21-gun salute. California Agriculture ought to have a 21-field salute.
No, make that a 63-field salute.

So, you spot a bug crawling up and down a plant in your garden.
What is it?
Plant bug? No kidding.
The common name for certain members of the Miridae family is--you guessed it--"plant bug." Entomologist Lynn Kimsey, who directs the Bohart Museum of Entomology on the UC Davis campus, quickly identified this little bugger.
"It's a Hemiptera," Kimsey said. Hemiptera, the fifth largest order of insects, all have a tubular beak for piercing and sucking. They're among the seven million insects in the Bohart Museum.
"Members of the family Miridae are the commonest Hemiptera in most areas of California," write entomologists Jerry Powell and Charles Hogue of UC Berkeley in their book, California Insects. "Many species attain high population densities, and most are specific to certain plants."
They describe the critters as "small, soft-bodied, elongate or oval bugs with prominent eyes and long, thin antennae and legs."
Most mirids, they say, suck plant juices (with their long beak) but some prey on other soft-bodied insects.
In case you're wondering, California has recorded more than 150 species of miriads.
The others, as they say, "await discovery."
In their book, Powell and Hogue list some of the species of plant bugs: ornate plant bug (Closterocoris ornatus), black grass bugs (Irbisia) and tarnishesd plant bugs (Lygus).
You can't go wrong, however, by calling it a "plant bug."
Pretty in pink
Now here's something that will tick you off.
You're taking photos of bumble bees and honey bees in tall grass near a wooded area, minding your own ISO, shutter speed and aperture. All's well with the world.
When you arrive home, there's an eight-legged visitor in your hair from the genus Dermacentor. That's the bad news.
The good news: You discovered the blood-sucking parasite, aka dog tick or wood tick, before it could embed or engorge.
This tick (below) is a reddish brown female dog tick I picked up in Marin County. It took a liking to my hair. My first tick. My first tick photo.
It is not something to crave.
Dog ticks look like spiders when their belly isn't full. They are typically found in tall grasses and wooded areas. They lie in wait for an unsuspecting host, like a dog bouncing through, and then attach themselves.
Not only are dog ticks painful but some can transmit human diseases like Rocky Mountain spotted fever and tularemia. Dog ticks can also induce tick paralysis. Another tick, known as a blacklegged tick, can transmit Lyme disease.
At the Center for Vectorborne Diseases, headquartered at UC Davis, some of the scientists research tick-borne diseases.
So, how do you remove a firmly embedded tick from your dog? Take your tweezers and firmly pull it out.
Preventive measures? The Centers for Disease Control and Prevention offers helpful tips. People are encouraged to wear light-colored clothing, long pants and long-sleeved shirts. Wearing light-colored clothing can help you detect them. Covering your skin can help avoid attachment. Some folks swear by insect repellent, too.
Key point: After a hike, check for ticks.
In your hair, too.
