Habitat and Ecology
It is found in leaf-litter, on low herbaceous vegetation, and in and around ephemeral ponds and swamps in primary tropical rainforest. It is an explosive breeder in the above waterbodies; eggs are deposited on the pond surface. It has been recorded from selectively logged areas (Bolivia); and lightly disturbed habitats (Peru). This species has an interesting mutualistic relationship with tarantula species.

Chiasmocleis ventrimaculata

Common name: Dotted humming frog[1]

Chiasmocleis ventrimaculata is a species of frog in the Microhylidae family.[2] It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, swamps, and intermittent freshwater marshes.

The frog is known to have a mutualistic relationship with the burrowing tarantula Xenesthis immanis.[3] The tarantula provides the frog protection from predators and a food source from insects feeding on the remains of its prey. The frog's foraging protects the tarantula's eggs from ants.[4]

This commensalism between microhylids and large spiders is common and occurs in various parts of the world. [5]
