The southern corroboree frog has a very distinctive pattern of black with bright yellow stripes. They are very small, only around long when fully grown. The female frog is usually larger than the male and can be as big as They mainly eat bugs, like ants, beetles and mites. They have a very different breeding cycle to most other frogs. Most frogs breed in spring, but these frogs only breed in summer during January and February. They use the wet areas to dig small holes for their mating and nesting. They lay between 16-40 eggs. The eggs hatch 4–6 months later when water levels rise and flood the nests. The frogs live as tadpoles for another 6–8 months. They change into frogs at the start of summer in December. They become sexually active after another two years. The frogs are not known to survive a second breeding season.
