Etymology

The word Adversaeschna is a combination of two Latin words: adversus, meaning opposite in physical position; and aeschna, derived from the genus Aeshna named by Danish entomologist Johan Fabricius in 1775.^[5] Adversaeschna brevistyla was described by Tony Watson in 1992 as being taxonomically isolated from other dragonflies in the genus Aeshna.^[1][5]
