Mexican wedgetail

Description

Acanthagrion quadratum, or Mexican wedgetail, is a pond damselfly of the family Coenagrionidae. It was first described by Edmond de Sélys Longchamps in 1876. Acanthagrion is a genus of damselflies. It is the dominant genus of damselfly at ponds and lakes in the Neotropics but A. quadratum is the only one found in North America. They are commonly known as Wedgetails because of the raised tip of the abdomen.
