The story behind our funniest animal name will definitely make you laugh. Howard Ensign Evans, an American entomologist, traveled around Australia in the late 1970s, collecting wasps to bring home and study. He mailed some to his friend and colleague, Arnold S. Menke.

Menke looked at the wasps and identified a couple of new species. He exclaimed, “Aha! A new species!” but his colleague, Eric Grissell, responded doubtfully, " Ha!”. Menke turned out to be correct, and the wasps were newly identified species of the Sphecidae family.

He named the first wasp Aha evansi to honor his friend Howard Evans and the second one Aha ha, as a joke.
