Bombus pullatus is a tropical, eusocial species of bumblebee native to Mexico and Central America. Unlike many bumblebee species, they live in colonies with multiple queens. The majority of this species occurs in the lowlands of Central America, with approximately 90% of colonies being found in Costa Rica. However they have been found at elevations higher than 3 km above sea level. Colonies have been confirmed in Guatemala, Honduras, Nicaragua, Panama and the south of Mexico.
Bombus pullatus is considered a more basal member of the genus Bombus compared to Bombus pauloensis and Bombus transversalis. Historically, Bombus pullatus has commonly been misidentified as Bombus pauloensis and vice versa in many collections. Molecular analyses (such as DNA profiling) of these specimens are required to accurately identify both species. This issue is why the IUCN has agreed to reject data on this species that is more southern than Panama.
This species is known to be quite aggressive, stinging humans within approximately 6 m of the nest if it is disturbed. Unlike most bumblebees, Bombus pullatus colonies contain multiple queens (a form of polygyny... Wikipedia →

With luck
About 10% of wildlife watchers report a Black-Clothed Bumble Bee sighting in Los Quetzales National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 56 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May and June
In those months about 20% of wildlife watchers report a Black-Clothed Bumble Bee in Los Quetzales National Park on a given day, against under 5% in August to April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-Clothed Bumble Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 parks where we can rate Black-Clothed Bumble Bee sightings, Los Quetzales National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Tenorio Volcano National Park (Costa Rica, about 10%) and Arenal Volcano National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-Clothed Bumble Bee is recorded against all the insects logged in Los Quetzales National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
