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,...

Henrietta and the Drone Fly: The Predator and the Prey
Henrietta, our Stagmomantis limbata praying mantis, perches on a Mexican sunflower (Tithonia). She is as patient as she is persistent. The drone fly, aka syrphid and also known as a hover fly or flower fly, makes the fatal mistake of touching down on the same blossom. Henrietta eyes it hungrily....

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...

Sharing the Nectar--But Not All at the Same Time
Everybody eats in the pollinator garden. Maybe not at the same time, but they all eat. We noticed a syrphid fly, aka flower fly/hover fly, heading toward a Mexican sunflower (Tithonia) in our pollinator garden. Alas for the fly, it was occupied. Occupied by a honey bee (Apis mellifera). No...

Can we share? As the honey bee keeps nectaring, the syrphid comes in for a taste. (Photo by Kathy Keatley Garvey)

About Those Drones,,,
Everyone's talking about the drones. You know, the unmanned aerial vehicles (UAV). Those flying robots cruising over our heads--some with cameras for journalistic and research purposes and others with "need-to-know" purposes. But in the entomological world, the word "drone" usually means a male...
