Bombus transversalis
In 3 days ~50% in a week ~80%
Bombus transversalis is a bumblebee specifically native to the Amazon Basin. It is most notable for its surface-level colonies which are built by the workers on the rainforest floor. Unlike its relatives, B. transversalis is able to thrive in a humid climate and fend off a wide range of predators because of its resilient nests. While there is great deal of information pertaining to their nests and foraging abilities, there is much more to be learned about relationships within the colony and life cycle of the bee.
Bombus transversalis is in the order Hymenoptera, which consists of bees, ants, wasps, and sawflies. It is in the family Apidae and in the genus Bombus. Most Bombus live in temperate climates and build their nests underground from abandoned tunnels. Bombus transversalis has adapted to tropical climates and builds its nests on ground surface. It is classified under the subgenus Thoracobombus. An example of a related species would be Bombus pauloensis. However, Bombus transversalis is the only one of this subgenus known to build their own nests out of leaves and twigs.

Possible
About 20% of wildlife watchers report an Amazonian Bumble Bee sighting in Manu National Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 366 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report an Amazonian Bumble Bee in Manu National Park on a given day, against about 10% in May, July–August and December–March, the lowest months. That is one of Manu National Park's driest months, with about 90 mm of rain against 290 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Amazonian 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.
Yes
Of the 2 parks where we can rate Amazonian Bumble Bee sightings, Manu National Park has the highest daily chance: about 20%. Next come Yasuní National Park (Ecuador, about 10%).
Same family: Apidae
The closest relatives of the Amazonian Bumble Bee that you can see in Manu National Park (family Apidae, Honey Bees, Bumble Bees, and Allies) are Belted Orchid Bee (about 10%), Three-Sectioned Orchid Bee (about 10%) and Melipona eburnea (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Amazonian Bumble Bee is recorded against all the insects logged in Manu National Park (39 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.
