Bombus pullatus is a tropical, eusocial species of bumblebee native to Mexico and Central America.

The majority of this species occurs in the lowlands of Central America, with approximately 90% of colonies being found in Costa Rica.

Molecular analyses (such as DNA profiling) of these specimens are required to accurately identify both species.

[4] This bee forages on many kinds of plants, including Miconia sp., Monochaetum sp., Solanum sp.

This bee can be rare in parts of its range with wet tropical climates because it is difficult to find a suitable dry nesting site and maintain it in such moist conditions.

[4] Their colonies are thought to consist of approximately 300 workers, however this is based on only counts from two individual nests.
