There's an old saying applicable to child-rearing: "First you give them roots, and then you give them wings."
Roots to ground them, to love them unconditionally. And wings for them to lift off and launch new beginnings.
Quote Investigator attributes the origin to newspaper editor Hodding Carter's book, "Where Main Street Meets the River," published in 1953. Carter credited a "wise woman" with saying that:
"A wise woman once said to me that there are only two lasting bequests we can hope to give our children. One of these she said is roots, the other, wings. And they can only be grown, these roots and these wings, in the home..."
But have you ever walked through a pollinator garden and been awestuck by the beauty of wings? The iridescence wings of a female Valley carpenter bee, Xylocopa varipuncta?
It was Sunday, May 21 and the feeding frenzy on our showy milkweed, Asclepias speciosa, was in full swing: it was a pushing, shoving and sipping match for the honey bees, carpenter bees, sweat bees, lady beetles, and syrphid flies.
But it was the wings--and wing venation--of a carpenter bee sparkling in the sunlight that caught our attention.
The wing venation "clearly shows a couple of characteristic features of Xylocopa wing venation: the long slender marginal cell and the 'boot-shaped'" second submarginal ('toe' pointing toward head end)," noted native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis, and co-author of California Bees and Blooms: A Guide for Gardeners and Naturalists.
Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology, also weighed in. "They are lovely. Not too many wasps or bees wings have this iridescence. That's an old lady by the way. Look how worn her wings are."
The LOL loved the showy milkweed. But she's the one that put on the show.
Talk about pollen!
The bumble bees, Bombus vandykei (as identified by Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis), were buzzing all over the Phacelia last week on the central campus.
One bumble bee carried a heavy load of orange pollen (collected nearby), while another, a small load of blue pollen. They both wanted the same flower.
I'll have what you're having! Move, please.
Sorry. I'm not finished here.
She didn't move. Not then.
Both the bumble bee and the plant are natives.
The genus Phacelia, also known by its common name, phacelia, or scorpionweed or heliotrope, is native to North and South America. Its genus includes some 200 species.
VanDyke's Bumble Bee is found in the Pacific Coastal states, including Washington, Oregon and California. Bombus vandykei is one of about 250 described species of bumble bees worldwide. All belong to the genus, Bombus.
The vandykei males are extensively blond, but not the females. In fact, the females are often confused with the yellow-faced bumble bee, Bombus vosnesenskii. (A distinguishing feature: on the vandykei, the yellow abdominal band is on T3 rather than T4.) See BugGuide.Net.
Want to know more about bumble bees and how to identify them? Be sure to pick up a copy of Bumble Bees of North America: An Identification Guide (Princeton University Press), co-authored by Thorp and fellow scientists Paul Williams, Leif Richardson and Sheila Colla. It won a 2015 Outstanding Reference Sources Award, Reference and User Services Association, American Library Association.

It's just like being in a Phacelia patch filled with bumble bees!
It was Saturday, April 18, the 103rd annual UC Davis Picnic Day, a campuswide open house, and several thousand folks filed into the Bohart Museum of Entomology to see the displays. The theme: "Bigger, Better, Buglier: Impressive Science."
Native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology, UC Davis Department of Nematology and Nematology, displayed male Valley carpenter bees he netted in the UC Davis Häagen-Dazs Honey Bee Haven (and later released there).
And in an amazing moment, a young boy, wearing a bumble bee t-shirt, walked up to see the bees. "My kind of guy!" quipped Thorp when he saw Adne Burruss, 6, of Irvine. Thorp is the co-author of Bumble Bees of North America: an Identification Guide (Princeton University) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday). Adne's mother, Sigrid Burruss, a geneticist, is a UC Davis alumnus.
The male Valley carpenter bee (Xylocopa varipuncta), a green-eyed blond, is also known as "the teddy bear bee." The female of the species is solid black. Thorp urged visitors to touch the carpenter bee. "Boy bees don't sting," he assured them. He also displayed specimens of bumble bees and other native bees.
Bohart Museum associate Wade Spencer, an undergraduate majoring in entomology, brought along his pet scorpions. Assisting him was Crystal Homicz, an animal biology major. She periodically pointed a black light on his scorpion to show the fluorescence. (Visitors were not allowed to touch the scorpions, which are known for their venomous sting.)
Entomologist and Bohart Museum associate Jeff Smith, who curates the butterfly and moth specimens, drew in visitors with his colorful butterfly and moth specimens and kept their attention as he talked about the places he's been and the insects he's seen.
Julianna Amaya, 10, of Martinez, was fascinated with the Australia walking sticks. She and sister, Jasmine, 14, and their mother, Rocio, watched it crawl up their hands. "Julianna is really into bugs," mom said.
The Bohart Museum, founded in 1946 and named for prominent entomologist Richard M.Bohart, is located in Room 1124 of the Academic Surge Building on Crocker Lane. Directed by Lynn Kimsey, professor of entomology at UC Davis, it is the home of nearly eight million insect specimens; a live petting zoo (including Madagascar hissing cockroaches, walking sticks and tarantulas); and a year-around gift shop stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Fran Keller, an assistant professor at Folsom Lake College who received her doctorate in entomology from UC Davis (major professor Lynn Kimsey) talked to visitors about insects and also kept busy with sales at the gift shop. Lady beetle t-shirts and monarch t-shirts proved popular.
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.

So here's this lady beetle patrolling a rosebud. It's early spring--April 15--in Vacaville, Calif.--and our little subject is looking for some tasty aphids. Or perhaps a mate.
Oh, a visitor is on my rosebud, heading right toward me. Identify yourself, please!
It's a wasp, a male parasitic wasp from the family Ichneumonidae (as identified by Robbin Thorp, distinguished emeritus professor of entomology at UC Davis).
The Ichneumon wasp is probably looking for a girlfriend. The lady beetle does not meet its expectations.
The wasp hurriedly flies off. Its mate, when it finds one, will lay her eggs in caterpillars, including such pests as armyworms, cabbage loopers, tomato fruitworm and tussock moths, much to the delight and appreciation of agriculturists. The eggs hatch into larvae, which develop inside the host, killing it. Adult wasps emerge and the cycle continues.
The wasp family is aptly named. "Ichneumon" comes from the Greek word meaning "tracker," a reference to its search for a host. Where's a caterpillar when you need one?
Charles Darwin seemed a bit troubled by this, describing these parasitic wasps as "feeding within the living bodies of caterpillars." The caterpillar shrivels up and dies.
Ichneumonidae is a big, big family of feeders. The number of described species? More than 24,000 worldwide. However, "estimates of the total species range from 60,000 to over 100,000--more than any other family in the order Hymenoptera," according to Wikipedia. That's probably more than any other family in the insect world, or for any other family, for that matter.
Says BugGuide.net: "They vary greatly in size and color; many are uniformly colored, from yellowish to black and others are brightly patterned with black and brown or black and yellow; many have middle segments of antennae yellowish or whitish. The majority resemble slender wasps but differ from the stinging wasps (Scolioidea, Vespoidea and Sphecoidea) in having longer antennae with more segments (usually at least 16). Many have long ovipositors, often longer than the body."
"Ichneumonids are notoriously hard to identify: aside from the sheer number of species, there are numerous cases of distant relatives that appear almost identical," BugGuide points out. "Any identification based solely on comparing images should be treated as suspect unless an expert has said there are no lookalikes for the species or group in question."
Have you checked to see what's foraging on your early spring blooms?
Our cherry laurels (Prunus laurocerasus) are blooming and the Andrena (mining) bees are zooming. These fast-moving bees are solitary ground-nesting bees that are early spring bees, according to native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology at UC Davis. The males emerge first.
"Females emerge several days later and, with only a few short weeks to live, waste no time with polite introductions," write and Thorp (who received his doctorate in entomology from UC Berkeley) and UC Berkeley professor Gordon Frankie in California Bees and Blooms: A Guide for Gardeners and Naturalists. The book is also co-authored by UC Berkeley affiliates: entomologist/photographer Rollin E. Coville and botany specialist Barbara Ertter.
"Mating is first on their agenda, followed by a quick meal of pollen to build up their ovaries," Thorp and Frankie point out. "They then dig or forage for materials to construct their nests, and for food for their offspring. At the end of the short flight season, the adults die and the new generation's life cycle continues inside the nest."
Thorp identified the bees below as two females: Andrena candida and A. nigrocaerulea. He and several colleagues teach The Bee Course, "an annual workshop for conservation biologists, pollination ecologists and other biologists who want to gain greater knowledge of the systematics and biology of bees." It's held at the Southwestern Research Station, Portal, Ariz., and this year's dates are Aug. 21-Aug. 31.
"Most North American Andrena species are black, dull metallic blue, or green and moderately hairy, with bands of pale hair on their abdomens," according to the Xerces Society for Invertebrate Conservation. "Females have large, velvety facial depressions (foveae) that look like eyebrows and large pollen-collecting hairs (scopae) on the upper part of their hind legs, seemingly in their 'armpits.' Despite a variety of striking colorations, Andrenan species are difficult to tell part."
If you have sandy soil and shrubs, that's ideal for them. You'll be the landlord and they'll be your tenants. "They nest in the ground, typically in sandy soil and often near or under shrubs. The nest entrance is usually marked by a small mound (tumulus) of soil."--Xerces Society.
Andrena is the largest genus in the family Andrenidae, with more than 1300 species, and about 261 in California. They occur nearly worldwide (Americas, Eurasia and the Old World tropics). The tiniest of the Andrena are only 7 millimeters long.
You may not see them. They're as tiny as they are fast, and they don't stop for photographs!
Sometimes you get lucky...
