Larvae and adults of these brine flies are abundant in hypersaline ponds isolated from main body of the Salton Sea. Larvae feed on algae. Both larvae and adult flies are probably significant food items for some of the birds feeding along the Salton Sea shoreline.

The distribution of this aquatic insect includes the southern United States, Carribean Islands, the west coast of the Americas from Peru to northern California, where it is found in a wide range of salinities. At the Salton Sea it occurs mainly in protected embayments or isolated pools at the fringe of the lake, where salinity is usually higher than the main body of the lake but where fish are scarce or absent. In tropical regions this species reproduces continuously, but in colder regions produces only 2-3 generations per year.
