Coqui frog (Eleutherodactylus coqui)


Regulatory Status: 

Hawaii Injurious Wildlife (Exhibit 5, Chapter 13-124)

Prevention and Control Category: 

Coqui are currently a rapid response species for the Hawaii Department of Agriculture (HDOA) and the Island Invasive Species Committees (ISCs) for all islands.


 The coqui is a small tree frog slightly larger than 2.5 cm (1 in) long. Round body shape. Coloration is variable from light yellow to dark brown. Broad rounded snout with obvious toe pads. Distinctive “ko-kee” vocalization. Found on ground level and in trees and bushes, but calls primarily from 1-2m (3-7 feet). Listen to the distinctive coqui call: and


  • No natural predators to keep populations in check (and no natural competitors), populations have reached 55,000 frogs per hectare in some Hawaii populations (24,000 frogs per hectare in Puerto Rico)

  • Eat huge quantities of insects, removing insects from forest floor to treetops.

  • Loss of insect services such as pollination

  • Disrupt the balance of vulnerable native ecosystems

  • Potential food source for snakes if they were to arriveelecoq2

  • Loud, incessant and annoying call from dusk until dawn

  • Adverse economic impacts on tourism

  • Decreased export plant sales

  • Disclosure requirement for real estate transactions, has resulted in decreased property values in some locations



Coqui frogs do not travel very far on their own, but when given the chance to hop on a nursery plant, flowers, or vehicle, they can quickly spread. Most coqui arrive on new islands through infested nursery plants and flowers. Intra-island, coqui travel by the movement of plants by humans and may hitch a ride on vehicles. The coqui frog is currently widespread on the island of Hawaiʻi, but is only known to be in a few locations on the island of Maui, Kauaʻi, and Oʻahu. They are not present on Molokaʻi or Lanaʻi. If you see them anywhere else on Maui, Molokaʻi, Lanaʻi, Oʻahu or Kauaʻi- let someone know!
