Research on this species in Cuba (Mancina et al 2013) suggests that it may forage higher up in the canopy than P. quadridens or P. parnellii; thus it may be harder for us to detect. In Cuba, diet (from analyses of stomach contents) is dominated by Diptera and Coleoptera; Orthoptera and Hemiptera are consumed less frequently (Silva Taboada 1979). Vertical and temporal segregation likely enables resource partitioning and coexistence with P. quadridens and Mormoops blainvillei (Emrich et al. 2013).

During monitoring efforts using harp traps at Windsor Cave, the male :  female capture ratio was 9 : 1.   Further research is needed to determine if females have a maternity crèche in another cave.  We also note the comment by Genoways et al. (2005): "Based on field observations it is difficult to draw many conclusions about reproduction in this species."
