This species is similar in overall appearance to H. chrysoscelis. Fairly large, forest-dwelling treefrog reaching 2.38 inches in snout-vent length. Skin is granular and warty. Dorsum is gray, brown or green in coloration with large, irregular dark blotches. Flash colors located on back of thigh are yellow or yellow-orange. Light spot below each eye. Highly arboreal. Call is a harsh trill and is heard from late March to early September. In the audio file to the right, both Hyla chrysoscelis and H. versicolor can be heard calling together. Hyla chrysoscelis is the faster paced and slightly higher pitched species. Females lay up to 2,000 eggs in groups of 6 to 45 in the water. The groups are either left floating freely or attached to aquatic vegetations. Species occurs primarily in longleaf pine forests in west-central Louisiana.
