Plonking Frog

Neobatrachus wilsmorei (Parker 1940)

Species Info Card | Updated 7 years ago

A medium to large-sized robust frog. The back is brown with five distinct narrow yellow stripes: a vertebral stripe plus two lines at each side that meet near the shoulder thus forming a 'W' on the back (easy to remember - W as in wilsmorei). The lower surfaces are creamy white and the toes have moderately extensive webbing. Maximum size is about 6 cm.

Breeding Biology

Breeding occurs in claypans and other shallow areas on warm evenings after summer rains and thunderstorms.

Eggs laid amongst vegetation. Tadpoles similar in appearance to other Neobatrachus tadpoles but attain larger sizes.


Arid and sandy areas that flood seasonally in summer.


Likely named after UWA chemist Norman Wilsmore, active in the early 20th century. One of the few species where a large initial of the species name appears on the back! ('W').


The call of this species is similar to the Shoemaker Frog, but has a more 'hollow' quality to it.
