Tiny - 3mm - black-and-beige bodied fly scuttling around on leaf-litter in Lusaka East (Zambia), close to a couple of artificial ponds but not so close as to clearly indicate association. Flicked its wings a lot.
Present from April-August at the very least. On one occasion, two of them seen within about 10cm of each other (whether either was responding to the other was unclear).
