Life History, Abundance, Activity, and Special Behaviors
Habits: Has only been found in primary forest and breeds in slow-moving stretches of forest brooks. Calling males were observed during the night. Males call from vegetation, 20-50 cm above the water in slow-moving portions of small streams.
Calls: A long pulsed chirping note and a rapid series of 5-6 short pulsed notes.
Eggs and tadpoles: Near the calling males at Andasibe, the remaining jelly of some clutches, probably belonging to this species, was still hanging from the vegetation over the brook (0.7 m above water).
