GREEN FROG (Lithobates clamitans)

The Green Frog has dorsolateral ridges - two lines down the back. (Bullfrogs don't have dorsolateral ridges)
Male: eardrum larger than the eye and generally a yellow throat
Female: eardrum about the same size as the eye and no yellow on throat
The male is the vocal one and sounds like a banjo string being plucked.
Two subspecies are the bronze frog and the northern green frog:
1) Northern Green Frog (Lithobates clamitans melanota) is native to the northeastern United States
2) Bronze Frog (Lithobates clamitans clamitans) is a subspecies found in the southeastern United States
