The feature species for July 2026 is Crinia tinnula, the Wallum froglet. The Wallum Froglet (Crinia tinnula) is a small (up to approx. 20mm) species of frog found in the coastal habitats of Queensland, ranging from as far north as Bundaberg, down to the very south-east corner of the State. These frogs are specialised, living predominantly in acidic, freshwater wetlands, such as Melaleuca swamps. Unlike many other species, the Wallum Froglet may breed throughout any season of the year, waiting for suitable weather conditions instead of a particular period on the calendar.

In addition to its small size, Crinia tinnula can be difficult to identify due to its highly variable colours and patterns. The back may be a variety of browns, greys, beiges or even red, and the underside, while typically white, can have dark patterns such as spotting or patches. This froglet also has no webbing present on its feet, and lacks padding or discs on its toes.
