About Eumenes fraternus Say, 1824
Wasps in the genus Eumenes can be recognized by their long, slender first abdominal segment: this segment is very thin at the front and widens toward the back. Eumenes fraternus is a member of this genus, measuring 15 to 20 mm (0.6 to 0.8 in) in total length, and has a similar appearance to other species in the genus. Its body is black with scattered ivory-colored markings. Forewing length differs by sex: males have forewings 8 to 10.5 mm (0.3 to 0.4 in) long, while females have forewings 10 to 12.5 mm (0.4 to 0.5 in) long. Compared to the otherwise similar species Eumenes crucifera and Eumenes verticalis, Eumenes fraternus has shorter pubescence on the first segment of its antenna. This wasp is distributed in eastern Canada and the eastern United States, with its range extending west to Ontario, Minnesota, Kansas, and Texas. In North Carolina, adult wasps are active on the wing from approximately April to November. It can be found in glades, rough shrubby areas, and forest verges.
