Terra Typica (Kaloula pulchra taprobanica): Punduloya, Ceylon, 4000 feet

K. taprobanica is distributed in Nepal, India and Sri Lanka. In Sri Lanka it is fround in the wet and the dry zone up to elevation of 500 m asl.

Life History, Abundance, Activity, and Special Behaviors
K. taprobanica is a fossorial species, but is also a good climber. This species is easier found after heavy rain next to human settlement: in rice fields and in water ponds along roads. Mating begins when the rain starts, and sometimes large aggregation can be found. Males call while swimming in ponds. Eggs float in a single layer on the surface of ponds. The tadpoles are black. This species is nocturnal. K. taprobanica feeds on a large variety of insects. De Silva (1995) reported feeding K. taprobanica with termites in capivity. The author has fed K. taprobanica with greater flies.
