Description

The bell frogs are large, long-lived and mostly aquatic tree frogs, with only small finger and toe pads. The Yellow-spotted Bell Frog is distinguished from other members of the group by its fully webbed toes and yellow spots on the groin and the back of the thighs. Elsewhere it is marbled green and gold, with black spots. This patterning varies greatly, but the pale green mid-back stripe is unvarying. The larger females may be up 9cm long. The call is a series of loud, droning grunts, like a distant motorbike. The tadpoles are large, growing to about 8cm long with a pinkish-grey body and yellowish fins.

Distribution

Historically, this species occurred in two separate highland ranges: on the New England Tableland, and on the southern and central tablelands from Bathurst to Bombala. Following the chytrid virus pandemic in the 1970s, this species went unrecorded for 30 years and was beliebed to be extinct, until it was rediscovered in 2009 on the Southern Tablelands. This population - near Yass - remains the only known extant site of the species.

Habitat and ecology

  • Require large permanent ponds or slow flowing 'chain-of-ponds' streams with abundant emergent vegetation such as bulrushes and aquatic vegetation.
  • Adults are active during spring and summer and bask on sunny days.
  • Move and forage at night on grassy banks or float on the water's surface.
  • Males call at night from the open water and breeding generally occurs during or following rain.
  • Eggs are laid amongst aquatic vegetation.
  • Shelter during autumn and winter under fallen timber, rocks, other debris or thick vegetation.
