Fly ID - SE TX, USA:

Oh yessssssssssssssssssssssssssssssss, this is a hoverfly, called Oblique Streaktail (Allograpta obliqua), family Syrphidae. Hoverflies that visit and pollinate flowers, as a group, are often called Flowerflies, as well.

A hoverfly larvae I found climbing over the flax during the rain. Either Allograpta (Streaktails) or Sphaerophoria (Globetails). Most hoverfly larvae in the Syrphini, and the wider subfamily, are predators of aphids, but if there were any on the flax they were probably half-drowned.
