Gray TreefrogsWell who knew? I had seen lots of color and texture variation in Eastern Gray Treefrogs in the past (see my previous post on the frogs and toads of northern Indiana here), but I had never noticed that bright yellow area on the ventral side, or the silvery spot under the eye, or the dark stripe from the snout through the eye to the shoulder. But this individual fits this description very well, and is indead an Eastern Gray Treefrog.
Hyla versicolor LeConte and Hyla chrysoscelis Cope
Identification: Frogs with enlarged discs at the tips of their toes and of highly variable color but with a bright yellow wash on the posterior and lower thighs and a light spot below the eye. Body length of adult frog is approximately 1 1/2 inches. The two species can be distinguished by voice, blood cell size, and chromosome count.
Description: Head wider than long, snout short and blunt; eye of moderate size with horizontally elliptical pupil.... There is usually a dark band from the snout through the eye to the shoulder adn a dark mid-dorsal spot that may cover most of the back or be broken into several spots. A rhomboidal silvery to light green spot below the eye is consistently present.... posterior surface of thighs and underside of tibiae with dark reticulum covered by chrome yellow to orange wash; belly white.
Now that I've written about these characteristics of gray treefrogs, I will probably remember them. But those facts that were new to me in the past that I haven't recorded may be gone from my ever-worsening memory until I hear them again. And this time, I think I will write them down.
