Make Way for the Weird and Wonderful Wasps
Meet the "meat bees." Yellowjackets, commonly known as "meat bees," in comparison to the "vegetarian" honey bees, will be among the wasps featured at the Bohart Museum of Entomology's open house from 1 to 4 p.m., Sunday, Sept. 25 in Room 1124 of the Academic Surge Building, 455...

Aren't You Supposed to Be Hibernating?
Dec. 22 marked the winter solstice, the first day of winter. But don't tell that to the western yellowjacket, Vespula pensylvanica. It's supposed to be hibernating, not flying. But there it is flying around--and sipping nectar--from flowering Algerian ivy climbing a fence in Vacaville,...

Quit Mimicking Me!
Last weekend a little critter made its first-ever appearance in our family bee garden. It was neither a grand entrance nor a grand insect. "A fly!" I thought, as I looked at its knoblike bristle or arista on the end of each antenna. But its body--what little I could see of it...

What to Do About Yellowjackets
The question begged for an answer. "It's yellowjacket time again. Does anyone have or recommend a good trap?" A Bay Area beekeeper today sought recommendations from ledEric Mussen, Extension apiculturist with the UC Davis Department of Entomology and Nematology. Mussen, who recently...
