HABITAT AND ECOLOGY
This species is usually found in anthropogenic habitats such as agricultural areas, ditches, artificial ponds, and lakes. It is also found in swamp forest (A. Diesmos pers. comm. March 2018). It breeds by larval development in nearly any body of available water.

THREATS
Available information indicates that this species is not subject to any significant degree of disturbance, which could threaten its survival at present. However, it is harvested for food, although not at levels that constitute a major threat to it. Invasive species Hoplobatrachus rugosus and Kaloula pulchra are now widespread across the Philippines and, in areas where this species occurs, there have been some possible observed declines in subpopulations although it is not considered to be a major threat (A. Diesmos pers. comm. March 2018). In areas where all three species co-occur, local communities have shifted to harvesting the two invasive species for food, which may have lessened the impact on this native species (A. Diesmos pers. comm. March 2018).
