Abstract - The duration of the development phases of workers, males and gynes was studied in Melipona beecheii, an economically important stingless bee species in southern Mexico. We also determined if gynes and male cells were distributed in clusters on the combs as in other Melipona where laying workers exist. The results showed that the total length of development for the workers was 52.72 ± 1.28 days. In the case of the gynes and males, it was 50.80 (± 1.52) and 53.43 (± 1.12) days, respectively. We found that clustering of male cells in M. beecheii was an uncommon occurrence. We suggest that the main factor explaining the reduced frequency of male cell clusters is that males are not worker-produced in this species, compared to other species of Melipona in which males are worker-produced. Factors related to pollen availability could determine the presence of clustered males in some colonies of this species.
