The eyes have it.
Look at the compound eyes of an insect. Some are colorful, some are drab. But they are all organs that detect light.
Most insects "have some sight and many possess highly developed visual systems," write UC Davis entomology professors Penny Gullan and Pete Cranston in the fourth edition of their textbook, The Insects: An Outline of Entomology, published by Wiley-Blackwell earlier this year.
"Virtually all adult insects and nymphs have a pair of large, prominent compound eyes, which often cover nearly 360 degrees of visual space," they point out.
If you're studying to be an entomologist--or thinking about entomology as a career--you can learn more about how "the basic components needed for vision are a lens to focus light onto photoreceptors--cells containing light-sensitive molecules--and a nervous system complex enough to process visual information."
If you're photographing insects, you know how quickly they detect movement. Cast your shadow on them and off they go. Move closer and off they go.
Sometimes it's a challenge, but in the end, the eyes have it.
Those yellow-faced bumble bees know how to put on a happy face.
The males and females frequent our bee friendly garden to sip the sweet nectar of lavender, catmint and rock purslane. The females collect both nectar and pollen for their brood.
I think we have a nest of them beneath the catmint.
Plant it, and they will come.
The yellow-faced bumble bee (Bombus vosnesenskii), as its name implies, has a yellow face, a mostly black thorax and abdomen, and a yellow band near the tip of its abdomen.
The ones below are males, according to native pollinator specialist and noted bumble bee expert Robbin Thorp, emeritus professor of entomology at the University of California, Davis. Although officially "retired" (not!), he continues to do research on bumble bees and other pollinators.
Thorp also monitors the half-acre Häagen-Dazs Honey Bee Haven at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis for bee species.
It's a treat to see the bumble bees there.
It's a treat to see them anywhere.
You gotta love those bumble bees.
It's time to pop open a bottle of champagne and do a happy dance.
Finally, finally, we saw a yellow-faced bumble bee (Bombus vosnesenskii) in our yard.
After a 20-year absence.
Dusted with yellow pollen, it (or rather he) was nectaring the rock purslane--he, along with assorted honey bees and hover flies.
This Bombus brought to mind the May 27th Webinar that bumble bee expert Robbin Thorp, emeritus professor of entomology at UC Davis presented on "The Plight of the Bumble Bees" at UC Davis.
At the Webinar, he focused on Franklin's bumble bee (range of southern Oregon and northern California) and now feared extinct.
Thorp, a fellow of the California Academy of Sciences since 1986, is a noted authority on bumble bees. In June he served as a key speaker at a public symposium on "The Plight of the Bumble Bees" at the Smithsonian Institution, Washington, D.C. His topic: "Western Bumble Bees in Peril."
Bumble bees need our protection.
As Thorp says: "“The loss of a native pollinator could strike a devastating blow to the ecosystem, economy and food supply."
A trip today to Marin County, with a side trip to the Marshall Post Office in Marshall, yielded a triple bonus.
A bumble bee, a honey bee, and a syrphid or flower fly all were nectaring flowers on the post office grounds, located right across from a restaurant and marina we were visiting.
They must have known it was National Pollinator Week. They were all sharing the same space.
"Insect pollinators, including honey bees, pollinate products amounting to $20 billion annually in the United States alone," say officials with the National Pollinator Partnership.
About 80 percent of the world's depend on pollination. And almost all pollinators are insects.
What better way to close out National Pollinator Week, which ends June 28, with photos of three pollinators? These images were captured right outside the tiny postage-sized Marshall Post Office.
National Pollinator Week certainly has our stamp of approval.
Signed, sealed and delivered.
A sure sign of approaching spring...
As the cold weather subsides, out come the overwintering queen bumble bees. They're gathering nectar and pollen, building their nests and laying eggs.
Lynn Kimsey, professor and chair of the UC Davis Department of Entomology and director of the Bohart Museum of Entomology, found a young queen bumble bee (Bombus melanopygus) on campus yesterday.
The confused queen managed to fly into Briggs Hall, home of the UC Davis Department of Entomology.
These particular bees, native to North America, are nicknamed "the orange-rumped bumble bees." They're basically your fuzzy-wuzzy, yellow-banded black bumble bees.
Last year UC Davis entomologist Robbin Thorp tended a nest of Bombus melanopygus on the Harry H. Laidlaw Jr. Honey Bee Research Facility grounds at UC Davis. The story behind the story: an area resident was seeking a temporary location for the bumble bees, which were nesting in his birdhouse. Thorp obliged.
The photos below:
Kimsey's queen bumble bee (which rates a solid 10 on a scale of 1 to 10 for fuzzy-wuzziness) and a bumble bee ready to take flight from the birdhouse. The bumble-bee-in-the-birdhouse photo, taken Feb. 29, 2008, received an online presence when the North Carolina State University Museum asked to borrow it to illustrate some text.
All hail the humble bumble bee...ever beautiful and ever resourceful./o:p>
