About Polychrysia esmeralda (Oberthür, 1880)
This species, Polychrysia esmeralda, has yellow eggs. Its bright green larvae move in a looper-style gait, like the majority of Plusiinae. Once a larva reaches full growth, it binds leaves together with silk, and spins a gold-colored cocoon inside this tied structure. The wings of adult Polychrysia esmeralda have a shining golden color. Adults resemble Polychrysia moneta closely, but differ in two key traits: the upperside of the wings is paler in P. moneta, and the curved extrabasal line located below the median vein of the forewings is simple in P. esmeralda, while it is double in P. moneta.
