It is Friday Fly Day!
And what higher day than a Friday to put up a picture of a syrphid fly nectaring on a tower of jewels, Echium wildpretii? All of us want “fairly” in our lives.
Syrphid flies, often known as “flower flies” and “hover flies,” are pollinators that hover over a blossom earlier than touching down.
“Most species are predaceous, mostly on aphids or mealybugs,” in line with the UC Statewide Built-in Pest Administration Program. “Some syrphids prey on ants, caterpillars, froghoppers, psyllids, scales, different bugs, or mites. About 100 to 400 aphids could be fed upon by every aphid-feeding larva earlier than it pupates, however this varies by the mature measurement of the syrphid relative to the aphids’ measurement.”
Of us who assume that each critter they see in, on, or round a flower is a honey bee ought to know a few distinguishing options: bees do not hover, and syrphids have just one pair of wings, whereas bees have two. “Their giant eyes and brief antenna additionally give them away,” notes Kelly Rourke in her U.S. Forest Service article on “Syrphid Fly (Sphaerophoria philanthus). “The absence of pollinium, or pollen sacs, is harder to see, however is one other distinction from a bee. Of the almost 900 species of flower flies (household Syrphidae) in North America, most have yellow and black stripes.”
Pleased Friday Fly Day!
