The Ant-lions Of Florida. Glenurus Gratus (Say)

One of the most striking ant-lions in Florida is Glenurus gratus (Say) (fig. 2). The richly dark-marked wings (fig. 2) are distinctive in Florida according to Stange (1980a). The unusual, 2-toothed mandibled larva (figs. 1,4,5,6) lives in tree holes (fig. 3). Adults can be seen flying in forested areas during the summer months and sometimes are attracted to lights. This species is found throughout peninsular Florida, and new records are given here from the Florida Keys. There are 8 known species in this predominately Neotropical genus. Banks (1922, 1928) has published keys to many species, and Stange (1970) has provided a catalog and discussed the taxonomy of the genus.
