Eumenes fraternus is a species of potter wasp in the subfamily Eumeninae of the family Vespidae. It is native to the eastern United States and Canada. The female builds a miniature pot out of mud in which it lays an egg and places a live caterpillar. Its developing larva feeds on this whereas the adult wasp feeds primarily on nectar.
Wasps in the genus Eumenes can be recognised by the fact that the first abdominal segment is long and slender, very thin at the front and widening towards the back. Eumenes fraternus is about 15 to 20 mm (0.6 to 0.8 in) long and is similar in appearance to other members of the genus. Its colouring is black with a scattering of ivory-coloured markings. The forewings are 8 to 10.5 mm (0.3 to 0.4 in) long in the male and 10 to 12.5 mm (0.4 to 0.5 in) in the female. It has shorter pubescence on the first segment of the antenna than do the otherwise similar E. crucifera and E. verticalis.
Eumenes fraternus is found in the eastern United States and Canada. Its range extends west as far as Ontario, Minnesota, Kansas and Texas. It is on the wing from about April to November in North Carolina and is found in glades... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Fraternal Potter Wasp is recorded against all the insects logged in Dallas (41 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
