Day 6 of National Pollinator Week: Meet the Drone Fly
It's Day 6 of National Pollinator Week. Meet the drone fly (Eristalis tenax), often mistaken for a honey bee. The late Robbin Thorp, UC Davis distinguished emeritus professor of entomology, used to jokingly call it "The H Bee," pointing to the "H on its abdomen. It's not a bee, though,...

A Case of Mistaken Identity
They can't drain your bank account. They can't open up new credit cards. They can't get medical treatment on your health insurance. But they are identity thieves, nonetheless. Meet the drone fly (Eristalis tenax), often mistaken for a honey bee. Indeed, it's about the size of a honey bee. In its...

Pollinators on the Beach? Fancy Meeting You Here
So you're walking along Doran Regional Park Beach in Sonoma County on Tuesday, Oct. 16 and thinking about the pollinators in your back yard. (Don't we all?) And then: what a delight to see. Apis mellifera (honey bees) and Eristalis tenax, syrphid flies (better known as a "drone flies")...

Musical Flowers: Jockeying for Position
You've heard of "musical chairs," that anxiety-driven elimination game involving chairs, music and players. When the music stops and a chair is eliminated, the players race for the remaining seats. No one wants to be the first loser. Well, insects, too, play "musical chairs," but with...

A Fly, Oh, My!
A fly, oh, my! On the approval scale, they don't rank nearly as high as honey bees, but some are often mistaken for them. Take the Eristalis stipator, which belongs to the family Syrphidae, the hover flies. It's about the same size as a honey bee and it's a pollinator. We recently spotted this...
