Bombus transversalis

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.

[3] Bombus transversalis has adapted to tropical climates and builds its nests on ground surface.

[4] Bombus transversalis is primarily found in the lowland tropical rain forests of the Amazon Basin.

[5] It was thence shown that although the two bees are distantly related, the Bombus transversalis still shows behavior of alerting its colony about food sources leading to increased activity in and out of the nest.

Using the twigs, leaves, and litter on the forest floor, worker bees cut up the debris into fragments and then bring these pieces back to the nest to build onto the canopy.

As such, the trails which have been observed of the Bombus transversalis serve a dual purpose in both foraging and nest construction.

[4] A queen Bombus transversalis must choose its nesting site very carefully if she hopes to have a successful colony.

This will give the workers a base to build the canopy for the colony and provide adequate shade for the nest.

Because of the structure of its nest with an interwoven canopy covering the colony, the bees are able to remain dry even during Amazonian deluges.

[3] Additionally, it is believed that when the sun is at its hottest, workers will stand at the entrance of the colony and fan the nest to reduce temperature and humidity.

[7] Since Bombus transversalis builds its nest on rainforest floors, it is very susceptible to predators on the ground.

Through observation of the Bombus transversalis and these moths, a new parasitoid wasp in the genus Apanteles was also discovered.
