The southern bell frog is New Zealand’s largest and most frequently encountered introduced frog. Its green and bronze-brown back is warty and has a pale central stripe; this rough skin separates it from the smoother green and golden bell frog.
Introduced in Canterbury in the late 1860s, it was spread widely through New Zealand apart from Rakiura/Stewart Island. It gives a deep rasping growl and eats beetles, slugs, earthworms, freshwater animals, frogs and small lizards.
Ponds and wetlands throughout much of New Zealand are productive, particularly on warm evenings during calling.
