Cricket Frogs

Go to a pond in the southeast and walk along the muddy edge, and you’ll likely see tiny frogs leaping into the water ahead of you. You’ll rarely see the frog beforehand; the first hint of its existence will be a little splash. They launch themselves many times their body length, springing from the weeds into the water as if assisted by wings. From the opposite side of the pond, you’ll hear repeated clicks, like stones being struck together.

If you can find one sitting still long enough to get a good look, you’ll see that it’s about an inch long: a slender, long-legged creature, with bumpy skin and a triangle on the back of its head. It will be some combination of brown, black, green, and gold.

There are two species of cricket frogs: northern and southern. The northern species has slightly longer legs and a slightly more rounded snout, but they are otherwise very similar. They sometimes interbreed where their ranges overlap. (Those shown in this post are the southern species or hybrids of the two.) Between the two species, they cover most of the eastern half of the US.

The breeding season depends on the local climate; in Florida they may breed year-round, while in the northern edge of their range it’s limited to spring. Adults eat insects and spiders, while the tadpoles are vegetarians and feed on algae. The tadpoles are actually longer than the adults, if you include their tails, which are long, transparent, and often black-tipped. The black tip may be useful in confusing predators into grabbing for the tail instead of the body. This is good, because cricket frog tadpoles are eaten by just about everything else in the water — dragonfly larvae, salamanders, fish, snakes, other frogs… The lucky tadpoles which survive can take anywhere from 4 to 12 weeks to metamorphose into adults.
