It's a fly, not a wasp

Eleanor Tauber took this picture of a Transverse Flower Fly [Eristalis transversa] yesterday, Aug 1 . Quite appropriate to its name, this insect was on a sunflower located a little north of Turtle Pond, close to 5th Avenue. For those interested in classification, it is in the order Diptera [as are all flies] and in the family Syrphidae.
