Bats of T. robustula were usually found associated with bamboo groves in both intact and disturbed habitats at elevations ranging from lowland up to 1200 m (Tu et al. 2017). They usually roost in small groups in bamboo internodes, entering through narrow vertical slits created by beetles (Phillipps and Phillipps 2016). The reproductive phenomenon of this species is likely to be similar to that of other bamboo bat species found in Peninsular Malaysia such as often give birth to twins. January–July is the major reproductive period coinciding with abundance of insect prey (see Medway 1972).

The species is tentatively regarded to be distributed on Borneo, Java, and Sumatra and the surrounding islands within the Sundaic region. On Sumatra, it was recorded at elevation of 1,200 m a.s.l. (Tu et al. 2017).

This species has been recorded from many protected areas.
