Tabatha Yang saw it first.
She's the education and outreach coordinator for the Bohart Museum of Entomology at UC Davis.
What she saw--in a grassy field at the Harry H. Laidlaw Jr. Honey Bee Research Facility, west of the central campus--was a golden ladybug, aka lady beetle.
It looked just like a yellow jelly bean.
Systemic entomologist Natalia Vandenberg of the Agricultural Research Service, U.S. Department of Agriculture, identified it as Coccinella septempunctata.
Tabatha is "holding an adult ladybug that is newly eclosed from the pupa," Vandenberg said. "Note that the flight wings are yellow in the teneral adult instead of grey and they are stretched out so that they can expand fully and dry properly. The pronotal markings and body shape identify this as a member of the genus Coccinella. When the adult first leaves the pupa the dark pigment of the pronotum is already present, but the elytral spots develop gradually."
"If you had watched the beetle for 15 minutes the spots would begin to show. There is a spotless Coccinella that occurs in California (C. californica), but what you have is most likely to be a 7 spot that hasn’t developed the spots yet."
We watched it for several minutes and then released it back into its habitat.
By now, it's no doubt formed those characteristic spots.
Somewhere out there is a yellow jelly bean....with spots.

The overwintering ladybugs tucked in the leaves of our tangerine tree are gone.
Sunny temperatures hit 75 degrees, and off they went. Guess they thought it was spring.
Anyhow, they made a glorious sight as emerged from the folds of a tangerine leaf. One perched on the top of a tangerine tree and then crawled up and down the leaf.
Natalia Vandenberg, a USDA employee with the Systematic Entomology Lab, Smithsonian's National Museum of Natural History, identified these as an introduced species, Coccinella septempunctata.
