Wings up! Let's go! The monarch fall migration is underway. "Unlike most other insects in temperate climates, monarch butterflies cannot survive a long cold winter. Instead, they spend the winter in roosting spots," explains Monarch Watch.
What we've been waiting for all season... A migratory monarch butterfly fluttered into our Vacaville garden at noon today (Tuesday, Sept. 17) and nectared on a Mexican sunflower, Tithonia rotundifola. Then she treated us to a butterfly ballet.
Writing my last blog post as the Livestock and Natural Resources Advisor for Placer, Nevada, Sutter, and Yuba Counties is bittersweet. When I became the advisor in 2017 (filling Roger Ingram's enormous shoes), I assumed I would stay in this job until I retired. Life had other plans for me.

So, here you are, a newly eclosed Western tiger swallowtail, Papilio rutulus, eager to sip some nectar from a Mexican sunflower, Tithonia rotundifola, in a Vacaville garden. It's a warm, windless day, and you're anxious to score, score, score.
From honey bees to butterflies to nematodes--those will be some of the topics when the UC Davis Department of Entomology and Nematology hosts its fall quarter seminars. The seminars begin Monday afternoon, Sept. 30 and continue every Monday through Dec. 2.
On Sept. 6, 2016, it happened. A monarch fluttered into our pollinator garden in Vacaville and touched down on a Mexican sunflower, Tithonia rotundifola. It wasn't just "any ol' monarch"--if there's ever such a thing as "any ol' monarch.
