The larvae of the splayed deer fly feed upon algae and organic matter in damp muddy soils. The adult female flies feed on mammalia blood, in order for their eggs to mature properly. When they bite, they inject saliva with an anti-coagulating agent that prevent the blood clotting. The structure of the ommatidia in the midregion of the eyes of the females of these bloodsucking flies could subserve high polarization assisting in host-finding. Adult males and females feed also on nectar and pollen of flowers.
