Green Treefrog

Hyla cinerea



  • adult sizes range from 1-1/4 to 2-1/2 inches
  • the female is larger than the male
  • it tends to match the color of the object it's on but not always (some color variations are shown in the photos above and at the right); usually colors range from shades of green to a putty brown, but other colors include reddish-brown (center column, second photo) and blue
  • it is most easily identified by white "racing stripe" down the side; sometimes the stripe has a dark border and sometimes it doesn't
  • it also has white on back of rear legs (center column at right, third photo down) and tends to have whitish "lips" and a whitish underside
  • it can change color quickly but the stripe is the same color; in rare occasions, the stripe may be minute or missing
  • sometimes the back appears to have small yellow "flecks"
  • toepads are medium sized and observable (photo above) unless the frog is at rest position (right column, first photo)
  • the tympanum is greenish to green-brown while the Squirrel Treefrog's tympanum is more brown to bronze


  • small insects including crickets, beetles, moths, caterpillars


  • regular call
    • a ringing quenk-quenk
    • males call approximately 75 times/minute during mating season
    • from a distance sounds almost cowbell-like
    • calls most frequently prior to rain or on humid evenings, especially when barometric pressure is dropping
    • when males call to attract females, usually on vertical branch no more than 2-3 feet above water surface
    • usually call from April through late October
    • call higher pitched than Cuban or Squirrel Treefrog
  • rain call is a single, high-pitched bark
  • mp3 (recorded by Ralph Arwood)


  • on plant stems, in trees and shrubs near water
  • stays relatively close to the ground
  • most active at night


  • entire state of Florida, and elsewhere in the Southeastern United States


  • can breed toward end of first year
  • breed late spring to early summer
  • breed in water at least several feet deep in permanent ponds (most other frogs breed in shallow temporary ponds created by rainfall)
  • female lays small masses of eggs on roots of floating vegtation; egg mass forms and grows as it absorbs water, eventually appearing jelly-like just below water surface
  • eggs black to very dark brown and white
  • eggs hatch in 4-6 days
  • tadpoles to about 1-1/2 inches, greenish, long pointed tails, usually with creamish stripe from nostril to eye
  • tadpoles change into frogs in about two months, usually from July to early October
