Nest Architecture of Tetragona clavipes (Fabricius) (Hymenoptera, Apidae, Meliponini)

The aim of this study was to describe the nest architecture of Tetragona clavipes colonies, and to compare its features with other stingless bee species. The measurements were made on 10 colonies in terms of brood chamber, brood cells, royal cells, food pots, pillars between combs, and population. Brood chamber (= 3117.9 ± 1230.6 cm3) of spiral-shaped combs were all in the center of the nest. The values of equatorial diameter of brood chambers (= 14.33 ± 3.03 cm) can be useful to scale bee boxes. The height and width of food pots (= 3.42 ± 0.39 cm; = 2.21 ± 0.23 cm), and brood cells (= 6.37 ± 0.32 mm; = 3.73 ± 0.35 mm) were statistically different among colonies. The measurements of the internal nest structures of T. clavipes were similar to the few other reported studies of this species. T. clavipes nests presented only few differences from other stingless bee species. This species has large potential for honey production, which has not yet been explored and deserves attention in future studies.
