Overview
The arroyo bluet (Enallagma praevarum) is a damselfly of the family Coenagrionidae, native to the western United States, south to southern Mexico. It is associated with slow-flowing streams or lake margins with emergent vegetation.
Anatomy and morphology
Male
Males have blue eyes, accompanied by oval, raindrop shaped turquoise spots above each eye. Their abdomen is blue with large black rectangular spots lining the top, ending in an abdomen tip of the same color set.
Female
Females possess the same build as males, but can also be found in tan or lighter blue shades rather than turquoise. Their legs are a lighter brown color (as opposed to black), and the spots above their eyes are usually larger than their male counterparts.
