Two crews from the Hawaii Department of Agriculture captured three coqui frogs last night in separate areas of Oahu.
One coqui frog was found on a boat at a residence in Kahaluu and the others at nurseries in Kaimuki and Kunia.
The boat had come from Hilo, according to Scott Enright, chairman of the Board of Agriculture, and Dr. Neil Reimer of the Plant Industry Division of the state Department of Agriculture.
"In this case there was a boat that came in (and) had two frogs on it," said Reimer. "We sent our staff out; they were able to capture one. The other one got away but we know where it's hiding. We'll go out again and get that other one."
All three incidents were reported on Monday and Tuesday of this week by neighbors of those properties who reported hearing the coqui frog's distinct two-tone mating call.
"Our staff on Oahu have been diligent in following up on calls from the public and have been able to eradicate coqui frogs on this island," said Enright. "As with any potential invasive species, we encourage residents to be our eyes and ears and report possible infestations."
It is suspected that the coqui frogs found at the nurseries hitchhiked from Hawaii Island on plant material.
There have been few calls to report coqui over the past few months, but the frogs become more active as the weather gets warmer, which may account for the number of reports this week.
"It's a concern that one's found in one night," said Reimer. "And so what we do is whenever we get reports of coqui frogs on Oahu, we always follow up.
