Legs mainly yellow. Insect on a leaflet of Dockweed.
No interactions present.
So far, in 2013, I have accumulated 15+ observations of small Platypalpus-like flies on vegetation in the body of our Reserve. No Tachydromia or Tachypeza were among them, and these genera may well be exclusively active on surfaces, such as walls, fences and tree bark. (“An iSpot Search: “Stockway Dance Fly” should provide two examples).
Some of the present flies seem blacker than others but I can’t yet exclude an effect of the light.
The Diptera.info Gallery (Hybotidae) includes images of Platypalpus sp. as predators.
