Tachypompilus unicolor unicolor (Banks) (Western red-tailed spider wasp)

The entire body of this subspecies, including antennae and legs, is bright ferruginous in color, although the common name implies that only the end of the abdomen is ferruginous ( Fig. 11). The overall ferruginous coloration of T. u. unicolor contrasts strikingly with the appropriately named Asiatic red-tailed spider wasp, Tachypompilus analis (Fabricius) , in which only the apical four segments of the metasoma are bright reddish-orange and the rest of the body is black ( Fig. 12).
