Happy Valentine's Day!
While everyone else hands out little pink candy conversation hearts proclaiming "Bee Mine," "Miss You," "Call Me," "Kiss Me," and "I Love You," insect enthusiasts post photos of bugs "keeping busy."
We spotted an unforgettable scene recently in a flower patch behind the UC Davis Lab Sciences Building. The ladybugs (actually they're "lady beetles" because they're not bugs) were devouring aphids on the brittlebush (Encelia farinosa), a desert shrub we see throughout California, northwestern Mexico and the southwestern United States.
Quite contentedly, we might add. And doing a great job, we might also add.
But that's not all they were doing.
Brittlebush makes a good dining room, living room and bedroom.
Soon the flower patch will turn into a nursery.

Love is where you find it.
And sometimes you find it in a bean field.
Take the UC Dry Bean Field Day on Sept. 5 at UC Davis. As researchers, growers, UC Cooperative Extension personnel, industry representatives and other interested personnel fanned out in the bean fields west of the central campus, they may not have noticed the red among the green.
Two lady beetles, aka ladybugs, were doing what comes naturally.
We need more beneficial insects!

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.

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).

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.
