Fun Facts
Did You Know?
The Cajun chorus frog belongs to the genus Pseudacris, which translates to "false locust" in Greek. The name refers to the insect-like quality of the call, which early naturalists apparently thought sounded like locusts. It does not sound like locusts. It sounds like a small motor or a ratchet or someone running their thumbnail across a comb very rapidly. But "false locust" is the name we're stuck with, and the frog is unbothered by the inaccuracy

Cajun Chorus Frog:Cajun Chorus Frog
If you are in North Louisiana on a warm, rainy evening in late winter and you hear what sounds like a small motor running somewhere in the vegetation near a pond, you have not discovered a mechanical problem. You have discovered Cajun chorus frogs. Pseudacris fouquettei is a small frog with a loud voice, a name that means "false locust" in Greek, and a mating call that sounds like someone rapidly shaking a ratchet wrench in the bushes. The Cajun chorus frog is not subtle about its presence during breeding season, which is the entire point of breeding season from the frog's perspective. The male who calls loudest, longest, and most persistently wins breeding opportunities. The male who is quiet and shy does not win anything except more time to sit in vegetation and contemplate his life choices.
A Few More Facts
How they hunt and forage: Cajun chorus frogs are carnivorous and eat a variety of small invertebrates. The menu includes flies, mosquitoes, beetles, ants, spiders, worms, snails, slugs, and other small invertebrates that can be caught and swallowed whole. They may also eat smaller frogs or tadpoles if the opportunity arises, though this is not the primary diet. They feed mostly at night, hunting by vision in low light. The large golden eyes are adapted for nocturnal hunting, and the frog sits motionless in vegetation waiting for movement. When something small moves within strike range, the frog strikes with its sticky tongue, grabs the prey, and swallows it immediately. The entire sequence happens in a fraction of a second.

Cajun chorus frogs are easiest to experience by sound during warm, rainy evenings from February through April. Visitors with low or no vision can locate breeding sites by the rapid mechanical trill, then remain on firm ground or established paths while listening from a safe distance from wet ditches and pond margins. Night searches require a flashlight, careful footing, insect protection, and respect for private property and wetland edges.

Frequently Asked Questions
Does Cajun Chorus Frog live in North Louisiana?
Yes. If you are in North Louisiana on a warm, rainy evening in late winter and you hear what sounds like a small motor running somewhere in the vegetation near a pond, you have not discovered a mechanical problem. What else might you mistake for a Cajun chorus frog in North Louisiana?. If the frog you're looking at is small, brown, striped, and in North Louisiana, it could be either species, and you may need to hear it call to be certain.
How do you identify Cajun Chorus Frog?
Cajun chorus frogs are explosive breeders. They breed in late winter and early spring — typically February through April in North Louisiana — during brief windows when warm, rainy weather creates ideal conditions. Males move to breeding sites — temporary or permanent bodies of water including ditches, flooded fields, marshes, and pond edges — and begin calling. The movement is triggered by temperature and rainfall, and on the first warm, rainy evening after winter cold breaks, dozens or hundreds of male chorus frogs emerge simultaneously from upland habitat and converge on breeding pools. The males arrive first and establish calling positions. They do not defend territories in the conventional sense — there are no boundaries, no exclusive areas — but they do maintain spacing between calling males, and crowding is resolved through aggressive calling or brief physical interactions. A male that gets too close to another calling male will be challenged vocally, and if the intruder does not back off, the resident may approach and push or bump the intruder until he moves.

Is Cajun Chorus Frog dangerous to people?
How do Cajun chorus frogs and humans interact?
Cajun chorus frogs benefit humans primarily through ecological services. They control insect pests by eating mosquitoes, flies, and other nuisance insects. They pollinate plants — yes, frogs pollinate plants, though not as effectively as insects, they do visit flowers and transfer pollen incidentally while hunting insects on blooms. They serve as food for other animals, supporting populations of snakes, birds, and mammals that humans may value for other reasons.
They also benefit from some human activities. Agriculture, irrigation, and conservation efforts that create or maintain wetlands provide habitat for chorus frogs. Temporary pools in agricultural areas — flooded fields, ditches, livestock ponds — often support breeding populations of chorus frogs. The frogs are adaptable and can use a wide variety of wetland types as long as water is present during the breeding season.
On the other hand, Cajun chorus frogs suffer from human activities that destroy or degrade habitats. Urbanization, deforestation, pollution, and climate change all negatively affect chorus frog populations. The species requires both aquatic breeding habitat and upland terrestrial habitat for the non-breeding season, and development that eliminates either habitat type reduces population viability.
Cajun chorus frogs are not currently endangered or threatened, but they are vulnerable to population declines due to habitat loss and fragmentation. They are protected by state and federal laws that prohibit killing, collecting, or harming them without a permit. They are also monitored by wildlife agencies and researchers who study their distribution, abundance, behavior, and genetics to track population trends and identify conservation concerns.
