Other Common Names
Potter Wasps, E. fraterna (-us) is called "The Potter Wasp"
Explanation of Names
Probably comes from mythology. Menes was a king of Egypt, the king who united upper and lower Egypt in Greek accounts. Prefix eu- is Greek for good, true, thorough. An allusion to construction habits of the wasps, since the Egyptians were such builders? (Based on Internet searches.)
