Triatominae are insects notorious as vectors of Trypanosoma cruzi, which is the etiologic agent of Chagas disease, and other trypanosomatids. Triatomines of the genus Rhodnius are primarily sylvatic, nevertheless the occurrence of native species that invade households suggests their possible role in the transmission of Chagas disease. Rhodnius montenegrensis was first described in 2012, but the biological aspects of this species are still unknown. This study aimed to analyze the biological aspects of R. montenegrensis under laboratory conditions. The emergence rate was 63.0%, the mean time required for the emergence was 13.9 +/- 1.7 days, the biological cycle from egg to adult phase occurred in 105.2 +/- 9.2 days, the number of bloodmeals required for each nymphal stage to reach the next stage varies between a minimum of two and a maximum of seven. The weight gained after a bloodmeal varied between 10.6 times on 1st-instar nymphs and 3.9 times on 5th-instar nymphs. The adult specimens had the lowest gain of weight, reaching 2.2 times on females and 1.6 times on males. The sex ratio observed was 1:1. These data are relevant to understand the life cycle of this new described species and to elaborate more effective vector control strategies
