Don't you just love watching bumble bees?
This morning we watched a yellow-faced bumble bee (Bombus vosnesenskii) foraging on lavender. It moved quickly from one blossom to another, barely allowing us time for a "bee shoot." It was "bee gone" every time we aimed the camera.
Finally, it cooperated.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, identified it as a male, the first (photo of a male Bombus vosnesenskii) he's seen this season.
He thinks a prize is in order.
Thorp, co-author of the newly published Bumble Bees of North America: An Identification Guide (Princeton Press), and Davis photographers Gary Zamzow and Allan Jones and yours truly usually have a friendly competition to find and photograph the first bumble bee of the year, of the month, of the day, of the minute. Well, almost. It's "Bumble Bee Alert" a lot. On Christmas Day, I managed to capture an image of a black-tailed bumble bee, Bombus melanopygus, foraging on jade blossoms at the Benicia Capitol State Historic Park, Solano County. (The black-tailed bumble bees emerge much earlier than the yellow-faced bumble bees.)
Now a Bumble Bee Watch group has launched a website to track bumble bee populations across the U.S. and Canada. This is a collaborative effort among several conservation groups and universities, according to the website and they need your sightings, including photos. As a spokesperson said: "The information will help researchers determine the status and conservation needs of bumble bees, and help locate rare or endangered populations. They will also help with identification!"
Well, today, I watched one male Bombus vosnesenskii, and he watched me.
My prize? Just enjoying--and appreciating--nature at its finest.
(Note: How can you distinguish a male from a female Bombus vosnesenskii? Said Robbin Thorp: "Boy bumble bees have an one more segment in the antenna and the abdomen than females do. The tip of the abdomen is also more rounded. Male bees do not have any pollen transport structures. In bumble bees, this means that the hind tibia is much more slender than in females which have corbiculae (pollen baskets). In Bombus vosnesenskii there is a second partial yellow band on the abdomen on T-5."
"The most accurate test of female vs male bumble bees, is to pick up a specimen with a bare hand. If you get stung, it is a female, if not, it is a boy bee. Boy bees can't sting, because they have no stinger. But I do not recommend this test unless you already know the answer! :)"

Robbin Thorp saw it first.
Talk about an eagle eye.
Thorp, a native pollinator specialist and emeritus professor of entomology at the University of California, Davis, was monitoring the Häagen-Dazs Honey Bee Haven on Bee Biology Road, UC Davis, on July 23 when something caught his eye.
The California buckwheat was waving at him.
"While looking closely at the California buckwheat flower heads, I noticed a piece of one waving but there was no wind," recalled Thorp. "I watched a linear group of florets march across to another head. I tried to get a close-up on a flower head as background, but could not get the focus right."
So he placed the "unusual life form" on his finger to capture a better image. He captured it all right: a larva covered with buckwheat florets.
Later insect photographer Allan Jones of Davis, a regular visitor at the haven, obtained a spectacular photo of the camouflage.
Thorp identified the "unusual life form" as the larva of an emerald moth Synchlora (see http://bugguide.net/node/view/747823/bgimage). "The larva pupates with its camouflage still on then turns into a delicate green geometrid adult," he said. (See http://bugguide.net/node/view/316178/bgimage for the life cycle: caterpillar to moth).
Maybe it was serendipity, but Thorp found the larva during National Moth Week, July 23-29.

The photo just begs for a caption.
The praying mantis, with a female sweat bee grasped in its spiked forelegs, suddenly turns its head to look at the photographer.
Actually, three photographers: Davis insect photographers/bee enthusiasts Allan Jones and Gary Zamzow and I. We were shooting images in the Häagen-Dazs Honey Bee Haven, the half-acre bee friendly garden located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis.
Jones, admiring the first image (below), commented "I love the way the mantis has set breakfast aside to stare directly at you." With that, Jones served up three captions:
"Oh, is that your bee?"
"What are you looking at?"
"Threat or prey?"
Meanwhile, we were obviously interrupting the praying mantid's bee breakfast.
"The female sweat bee is carrying some pollen she toiled to provide for her young," said native pollinator specialist Robbin Thorp, emeritus professor of entomology at the UC Davis Department of Entomology. "The mantid is also ducking under a spider webline, and needs to be careful that it does not become the meal of another sit and wait predator. It's a real jungle out there!"
Thorp, who has been monitoring the garden since October 2009, a year before it was planted, has so far discovered 75 different species of bees--and counting.
Yes, sometimes amid the predators and the prey, it's definitely a "real jungle out there."
