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.

Some folks like to watch the grass grow, flowers bloom, or clouds drift.
Others just like to sit back and look for insects.
We spotted this seven-spotted lady beetle (aka ladybug) last Monday morning in the Häagen-Dazs Honey Bee Haven, a half-acre pollinator garden on Bee Biology Road at the University of California, Davis.
It's a predator, a beneficial insect, and an icon. As one of the most recognizable of all insects, it inspires clothing, art and jewelry themes; home décor; and video games, not to mention all things entomological and the citizen-scientist Lost Ladybug Project. It even prompted five states--Delaware, Massachusetts, New Hampshire, Ohio, and Tennessee--to declare it their official state insect. Never mind if these states are, in the political sense of the word, red or blue, denoting Republicans or Democrats. When it comes to state insects, they're all red!
Lady beetles are especially known for their voracious appetite for aphids, scale insects, mealybugs, mites and other soft-bodied insects. A gardener's friend. A biocontrol dream. An aphid's nightmare.
It's easy to see why the seven-spotted lady beetle, Coccinella septempunctata, is so named. Seven large black spots dot its red wing covers or elytra.
Indeed, if you know Latin, you know that its scientific name, septempunctata, means seven (septem) and spot (punctus).
We watched our seven-spotted friend prowl for aphids on a color-coordinated California fuchsia (Zauschneria californica mexicana).
It was "walking the line," Johnny Cash-style, keeping a close watch on...tasty aphids.

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!

It was lovely day today, in more ways than one.
During the lunch hour, we stopped by the Häagen-Dazs Honey Bee Haven on Bee Biology Road, University of California, Davis, and discovered more than just blossoms in the planter box filled with fava beans.
Ladybugs, aka lady beetles! Coccinellids!
We spotted five of them, and two were...ahem...in the process of providing the garden with more ladybugs. That's quite nice of them. We need more ladybugs to eat those pesky aphids and other soft-bodied insects.
Meanwhile, as the sun warmed the garden (60 degrees!), honey bees foraged among the blossoms and assorted ants and aphids crawled up and down the leaves.
The half-acre Häagen-Dazs Honey Bee Haven, located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, is living up to its name as a place for pollinators.

Photographers never tire of capturing images of ladybugs, aka lady beetles.
First of all, they're beneficial insects. You know when you photograph them that they're about to scoot, crawl or fly off to grab a tasty lunch--an all-you-can-eat aphid buffet.
Second, they're colorful. They brighten a garden, standing out like red Corvettes on a freeway.
Third, they're among the most recognizable of insects. Halloween costume companies relish in creating polka-dotted attire for the 5-and-under set. Nobody will ask "What are you supposed to be?"
Fourth, they're quite common. California alone has some 125 species of Coccinellids.
Worldwide, there are some 5000 described species.
Not too many people know, however, that many species in the family Coccinellidae secrete a nasty fluid. As UC Berkeley retired entomologist Jerry Powell writes in his book, California Insects, "...when disturbed, many species secrete a bitter, amber-colored fluid that is believed to have poisonous effects on vertebrates..."
Indeed, their red and black coloring warns "Leave me alone!"
