Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [5] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
After inspecting the nectar-like substance, these insects enter the flower laterally and land on the downward-facing labellum. When this occurs, the labellum rises, pressing the fly against the viscid pollinium and trapping it. To exit, the fly backs up, causing the viscidium to adhere to its thorax.
