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.
