    Ecology: Instream habitat: Larvae are usually found in mud and detritus or in algal mats and aquatic mosses in standing and flowing waters.
    Feeding ecology: Both larvae and adults are predacious on other insects, mainly Diptera.
    Habit:
    Life history: Adult emergence occurs from August to October for most Australian species. Some genera, especially of the subfamily Empidinae, have an elaborate courtship display in which prey is used as an essential stimulus initiating copulation, giving rise to the common name of ‘dance-flies’. Swarms are usually connected to mating behaviour.
