Adults range from 1.9-5.6 cm in length. Specimens are either greenish or brownish in color, often with dark stripes that often run the length of the body (Stebbins 2003). Males have a tan or greenish throat while the throat of females is typically white. Hyla eximia tadpoles have a brown dorsum with minute silvery-gold flecks, and a dark venter tinged with pale gold (Stebbins 2003).
