Physical Description
The slender pickerel frog
has bulging eyes, long legs, a lanky body, two big ridges between its
back and sides, and smooth skin. Pickerel Frogs are spotted, but with
irregular rectangular brown spots in rows. The basic color is yellow
brown with orange on the underside of the back legs. Pickerel frogs are
1 3/4 to 3 1/4 inches long. This frog's croak sounds like a long snore.
Diet and Feeding Habits
Insects
and other small invertebrates are favorite foods. Pickerel frog tadpoles
also eat plants. So they would be carnivores, and their diet consists
mostly of small insects & other invertebrates. And frog is a prey
for snakes.
Reproduction
Pickerel frogs begin
to reproduce at two years of age. In spring males begin calling to
attract females. The female lays a blob of 700 to 3,000 eggs in the
water. It takes about two weeks for the eggs to hatch and 8 to 11 weeks
for tadpoles to develop into frogs.
Habitat
Pickerel Frogs often inhabit
cool, wooded streams, and seeps. In the summer they are found in grassy fields.
Their habitat has to be wet & moist.
Role in the Ecosystem
Pickerel Frogs are
nocturnal and rouse from hibernation in early spring. They hibernate
from October until around March & April. You may hear a steady
low croak, that maybe calling from under water. It's a carnivore,
it eats insects. This species does not seem to adversely affect humans
at all. These frogs are not of great economic importance to humans. They
are not kept as pets due to their skin secretions. They are occasionally
used as fishing bait for anglers.
