It's Friday Fly Day!
It's Friday Fly Day--and time to post images of a syrphid fly. Syrphid flies, often mistaken for honey bees, are pollinators, too. Also known as flower flies and hover flies, syrphids hover over a flower before touching down. "Most species are predaceous, most commonly...

Behold: A Mexican Cactus Fly on a Mexican Sunflower
It's not often you see a Mexican cactus fly, Copestylum mexicanum, nectaring on a Mexican sunflower, Tithonia rotundifolia. At first glance, you may think the insect is a carpenter bee or bumble bee. Then you see it hovering. Then you see its head. Then you see its...

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...

Flies, Maggots and Forensic Entomologists at Bohart Museum on Sunday, July 9
Do you know the importance of maggots? Have you ever wanted to talk to a forensic entomologist? Ever wanted to create "maggot art" in a family friendly environment?Members of the North American Forensic Entomology Association (NAFEA) will be special guests and presenters at the open house...

Maggot art is created by dipping a maggot in non-toxic, water-based paint and letting it crawl on canvas (paper). This is a popular activity at the campuswide UC Davis Picnic Day. (Photo by Kathy Keatley Garvey)
