Unlike other members of its genus (which utilize Hymenoptera), Anthrax georgicus is a parasitoid of tiger beetle larvae. Adults can frequently be seen hovering in areas with dense tiger beetle congregations as they attempt to oviposit into the larval burrows. Once the egg hatches, the fly larva attaches as an external parasitoid and feed on the hemolymph, developing slowly while the beetle larva grows. Eventually, as the tiger beetle larva nears maturity, the Anthrax larva devours it, and pupates in the burrow. This species can be a major source of mortality for some tiger beetle species, and often a substantial percentage of tiger beetle larvae at a site may succumb to parasitism. (Knisley & Schultz 1997)
