Ah, Ladybugs!
Consider the lady beetle, aka ladybug.
It's not a bug, but a beetle. It belong to the family Coccinellidae, and scientists have described about 5000 species worldwide, and about 450 in North America.
Some quick facts...
Ladybugs are not always red with black spots. The colors can be red, yellow, orange, gray, black, brown and pink. And, not all ladybugs have spots. Some have stripes and some have neither spots nor stripes.
Coccinellid are omnivores, dining on soft-bodied insects such as aphids, as well as plants. Aphids? A single ladybug can eat some 5000 aphids during its short life span of three to six weeks.
Ladybugs are considered good luck. If a ladybug lands on you, Lady Luck is supposed to smile on you.
This ladybug (below) landed on me on the grounds of the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis.
I'm still waiting for Lady Luck.

Ladybugs Coming Up in the World
Decisions, decisions...
Where's the best spot for the new residents of my garden?
I acquired two ladybugs last Saturday during the 99th annual UC Davis Picnic Day. Background: as part of the campuswide celebration, the Department of Entomology annually hosts an all-out bugfest at the Bohart Museum of Entomology and at Briggs Hall. And keeping with the Briggs Hall tradition, the UC Statewide Integrated Pest Management Program gifted picnickers with the treasured ladybugs.
Now ladybugs aren't really "bugs"; they're beetles. Neither are they all "ladies"; some have manly qualities. (Gender issues may confuse us, but not the lady and gentlemen beetles.)
A ladybug is a good beneficial insect. It can devour an estimated 5000 aphids in its lifetime (three to six weeks).
So, every year for the past several years, I've adopted two ladybugs, chauffered them home, and tucked them in our garden. "Please eat the aphids," I tell them.
And they do.
They're good at following instructions.
Last year they took up residence in a bed of red roses. This year, they're coming up in the world--a high rise. A tower of jewels (Echium wildpretii) is "home sweet home."
Life doesn't get any better than this if you're a ladybug (and any worse if you're an aphid).

Sure Sign of Spring
What's red and black with yellow all over?
Ladybugs, aka lady beetles or ladybird beetles, laying their yellow eggs.
It's a sure sign of spring when aphids emerge, and ladybugs feast on them. One ladybug can reportedly eat 5000 aphids in its lifetime.
That's a lot of aphids!
Meanwhile, the aphids in the fava beans at the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden on Bee Biology Road, University of California, Davis, are doing their part.
The garden, located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, is teeming with aphids on the fava beans.
And teaming with ladybugs in the process of adding more ladybugs to the garden.
If you're looking to get involved with ladybugs as a citizen scientist, Cornell University, Ithaca, N.Y., hosts "The Lost Ladybug Project" to spotlight the ladybugs of North America. On the website, you can learn to identify them, understand their biology, and upload photos.
And it wouldn't hurt to include a photo of a ladybug dining on a scumptious aphid.

Home Sweet Home
These displays inform, educate and entertain.
The California State Fair, Sacramento, traditionally features an Insect Pavilion, which includes exotic and invasive species. This year's state fair also showcased UC Davis displays: insect specimens (and live ones, too) from the Bohart Museum of Entomology and a bee observation hive from the Harry H. Laidlaw Jr. Honey Bee Research Facility.
For the last several years, the Dixon May Fair's Floriculture Building has housed Bohart specimens and a Laidlaw bee observation hive.
The 63rd annual Solano County Fair, Vallejo, now under way, is also bee-and-bug friendly. If you head over to McCormack Hall, the first thing you see is a skep or dome-shaped bee hive. (Beekeepers in many parts of the world still use skeps, commonly made of twisted straw.)
The McCormack Hall skep symbolizes "Home, Sweet Home," the theme of the fair.
Last Sunday we watched McCormack Hall superintendent Elisa Seppa and assistant superintendent Gloria Gonzalez prepare the ceramic skep/bees/bears display (on loan from the California State Fair), as another Solano County Fair employee Deborah Miller lent her artistic touch to the exhibitor displays.
The fair, which opened Wednesday, Aug. 1 and continues through Sunday, Aug. 5, also includes a number of insect-themed work from exhibitors. This is sort of like BYOB (Bring Your Own Bug.)
Rachel Dalmas, 15, of Fairfield is exhibiting a close-up image (and a best-of-division winner) of a flameskimmer dragonfly. Desirae Rivas, 8, of the Travis Youth Center, painted a ladybug and titled it quite succinctly: "Lady Bug Painting." It won a blue ribbon.
Is there a (future) entomologist in the house?

Ladies (and Men) in Red
I don't know how long they'd been in the container, but they were anxious to leave. If you're a ladybug, a house is not a home without aphids.
Members of the California State Grange distributed these tiny containers of ladybugs at the California Agriculture Day on Wednesday on the State Capitol grounds. Grateful little kids excitedly exclaimed "Ladybugs! Ladybugs!" Their parents murmured "Yes! Yes! Great for the garden."
And that's exactly what we did with ours.
We had a red rose bush just waiting for them.
We removed the lid, tipped the container, and the two ladybugs raced out, right to an all-you-can-eat buffet of juicy aphids.
If you're yearning for your very own ladybugs, be sure to attend the 98th annual UC Davis Picnic Day on Saturday, April 21. The statewide UC Integrated Pest Management Program (UC IPM) traditionally gives away ladybugs at the entrance to Briggs Hall.
The UC Davis Department of Entomology, housed in Briggs Hall, will be hosting cockroach races, termite trails, maggot art and honey tasting and scores of other activities. This year, due to popular demand, Extension apiculturist Eric Mussen will be doubling the amount of honey. (Check out last year's entomological photos at Briggs Hall and at the Bohart Museum of Entomology.)
Meanwhile, the good folks planning the campuswide Picnic Day invite all to attend. They wrote on their website: "This family friendly event is free for all to come and experience the richness of diversity and achievement at UC Davis and the surrounding community in the areas of research, teaching, service and campus life."
And experience the wonderful world of ladybugs!
