The coqui frog was accidentally introduced into Hawai'i from Puerto Rico in about 1988. Aside from being a major noise nuisance, the frogs pose a threat to Hawai'i’s island ecosystem. Coqui frogs have a voracious appetite that puts Hawai'i’s unique insects and spiders at risk. They can also compete with endemic birds and other native fauna that rely on insects for food. The frogs are quite adaptable to the different ecological zones and elevations in the state and have been found from sea level to 4,000 feet elevation (at sites in Volcano on Hawai'i).
