Flies seem to be in the news a lot lately.
But have you ever looking closely at a common green bottle fly Lucilia sericata, also known as a blowfly?
Ever admired their brilliant metallic blue-green coloration? Ever thought about them as pollinators (they are sometimes!) but of course, that's not what they're known for.
They're known for their forensic, veterinary and medical importance. They are nature's recyclers when the females deposit their eggs in carrion.
But they're also beautiful.
We captured these photos of a green bottle fly on a tropical milkweed, Asclepias curassavica, in our garden. The red and yellow blossoms contrasted nicely with the stunning fly coloration. Nature's art.
Indeed, flies are an integral part of the annual UC Davis Picnic Day (cancelled this year due to the COVID-19 pandemic and precautions). What's a picnic without flies?
Forensic entomologist Robert "Bob" Kimsey of the UC Davis Department of Entomology and Nematology always staffs a booth at Briggs Hall where he holds forth as "Dr. Death" with his microscope and specimens as he encourages--and fields--questions from the thousands of picnickers. (See Bugs at Briggs)
Also at Briggs Hall during the UC Davis Picnic Day, "Maggot Art," is extremely popular. The artists, mostly children and teens, dip a maggot into water-based, non-toxic paint and drop it onto a white piece of paper and let it crawl. The finished product often finds its way onto a refrigerator, inside a frame, or as as an unexpected gift to grandparents. Certainly it's a conversation piece.
Meanwhile, mark your calendar for April 17, 2021, the scheduled date of the next UC Davis Picnic Day.
Dr. Bob, the flies, and the maggots will be waiting.
