There are approximately 5,000 dragonfly species, 20,000 grasshopper, 170,000 butterfly and moth, 120,000 fly, 360,000 beetle, and 110,000 bee, wasp and ant species described to date. Almost all of those can fly. Many could be described as small. Your description leaves us with approximately 785,000 possibilities.
So, either give us some information that approaches even vaguely detailed or google "fruit fly".
