It's Friday Fly Day, when folks post images of flies.
Flies seem to the entomological equivalent of Rodney Dangerfield's "I-don't-get-no-respect" quote.
So how about a black syrphid fly, a Mexican cactus fly, Copestylum mexicanum, nectaring on a Mexican sunflower, Tithonia rotundifolia?
The genus Copestylum includes more than 350 species in the new world, according to Martin Hauser, senior insect biosystematist with the Plant Pest Diagnostics Branch of the California Department of Food and Agriculture (CDFA).
The female Mexican cactus fly lays its eggs in rotting or dying cactus tissue.
This fly, about 3/4 of an inch long, is a delight to see in a patch of Mexican sunflowers mostly frequented by honey bees and Gulf Fritillaries. It's big. It's bold. And it's beautiful.
Happy Friday Fly Day! Respectfully...
