These pictures are of an unknown Picture-Winged Fly, I shot about two months back. I submitted it for identification to experts, but didn't get any reply yet. Picture-Winged Fly is a name used for all species in the family Ulidiidae. They are commonly found in moist places or on plants and flowers. Adults feed on nectar or fluids from decaying plant material. Larvae feed on dung and on decaying plant material. They got the name Pictures-winged Flies, because of the patterns of bands or spots on their wings.

Water lettuce (Pistia stratiotes) is a single species of aquatic plant in the genus Pistia, family Araceae. It’s also called water cabbage or Nile cabbage.
