Description
Physical Description
Species Hyla squirella
Size: A small Treefrog, 2.2 - 3.8 cm (7/8 - 1.5 in) in length
.
Color: Bright green to dark brown, with many variations
. An individual may be different colors at different times, depending on temperature
, activity, stress, and other factors
. It may or may not be spotted, depending on these same factors. There may be a light stripe
extending along its side from the top of the mouth
to the thigh. This stripe has an indistinct lower edge
. It may also have a dark mark
between the eyes.
The Squirrel Treefrog is a smaller frog
attaining lengths under 2 inches. This species is highly variable in color and pattern
. A given individual can change color from green to brown and from spotted to plain
. There may also be a light stripe along the side of the body. It is therefore generally suggested that this treefrog be identified by a process
of elimination: Gray and Bird-voiced Treefrogs have a white spot under each eye; Pine Woods
Treefrog has light, round spots on the rear
of the thigh; the Cuban Treefrog is larger and warty; the lateral
light stripe, when present, has an indistinct lower border
in contrast to the Green Tribe
that has a well defined lateral stripe
; Chorus Frogs in general have smaller toe discs and less toe webbing than Treefrogs.
Habitat
It can be found among trees or shrubs , in open pine woods , in swamps , under leaf litter , or even around housesAdults can be found hiding under bark , in hollow tree holes, or really anywhere that is close to moisture and food. This frog is nocturnal , hiding in vegetation during the daytime. . At night it is common around outdoor lights where it hunts insects.
Ecology: Open woods
, cities, and towns; thick low vegetation near water; wherever there is adequate moisture, hiding places, nearby standing water
, and insect food. When inactive
, hides under loose
bark
, palm leaves, in tree
holes
, in gardens, and in other protected sites. There is a non-breeding "rain call
" given by males from trees and bushes when rainfall is impending. Eggs
and larvae develop in flooded roadside ditches, flat woods ponds
, swamps
, and small, semi permanent stock-watering ponds. Males call from debris
and twigs
above water, on ground
near water, or hidden in grass
clumps
adjacent
to permanent or temporary rain pools
of moderate depth (Schwartz and Henderson 1991).[1]

Biology
Reproduction
This Treefrog breeds
from March to late August or early October. Usually breeding takes place in vegetation. Their call
sounds
like a duck's quack or sometimes like a squirrel.
Fertilization is external. The female lays
up to 1,000 eggs
in shallow, standing water
with abundant vegetation. Hatching
to transformation
takes six weeks.
Behavior
The Squirrel Treefrog is nocturnal . It spends the day resting in moist hiding places. It is called a "rain frog" because it is one of the species that calls only during and after summer showers.
In addition to mating calls , the Squirrel Treefrog has a call that it makes when it rains. This call is usually made from sites far from the breeding pond and sounds like some of the sounds that squirrels make, hence the name .

Similar Species
At least eight species can be confused with this Treefrog. Identification is largely by a process of elimination. The Squirrel Treefrog does not have spots or stripes on the inner thighs like those found on the Pine Woods Treefrog and on Northern and Southern Cricket Frogs. It does not have dark spots on its flanks as does the Ornate Chorus Frog. It does not have light spots under its eyes like the Gray Treefrog and Bird - voiced Treefrog do, or a stripe through the eye like that found on the Little Green Frog. It also lacks the "X" on the back that distinguishes the Spring Peeper. The Squirrel Treefrog usually does have a light side stripe, but its bottom border is not as distinct as on the Green Treefrog. The Squirrel Treefrog also has larger toe disks and more webbing on its back feet than other Chorus Frogs do. The ranges of all the Chorus Frogs in Georgia except the Mountain Chorus Frog overlap the Squirrel Treefrog range.
