[2] These bees reside mainly in the forests of Brazil, nesting on the surface of the ground.

[4] In South America, most of the bumble bees are distributed among the Andes mountains and in temperate regions, with a few species being observed in the warmer lowlands.

Five of these six are very closely related, but the sixth, the Bombus morio, belong to a distinctive clade.

Instead, the excretion system in Bombus morio, consisting of the Malpighian tubules, ileum, and rectum, gives the bees an efficient method of keeping homeostasis.

The Malpighian tubules are significant for excretory features by throwing out excess and unnecessary solutes.

Together, the two organs work together to achieve homeostasis within Bombus morios bodies despite the lack of rectal papillae.

[8] The midgut of Bombus morio is made up of three cell types that play crucial roles in the digestion, absorption, and hormone production.

In this manner, the Bombus morio are able to remove the pollen from the anthers of the flowers with stamens.

This, combined with its deposition on the stigma of flowers with pistils, allow the Bombus morio to be extremely effective pollinators.

It was observed that a single visit from the Bombus morio was enough for pollination systems to lead to fruitification.

[14] The Bombus morio display a specific type of behavior to release the pollen from the flowers called the buzz pollination.

[4] The Bombus morio make their nests in the neotropical regions on the surface of the ground.

When humans are stung by the Bombus morio, serious injury and even death can occur when not properly taken care of.

When stung, victims experience immediate intense pain, and a reddish-orange spot appears, indicating bleeding traumatic lesions at the site of the bite.

Within two hours of the bite, the stings can cause nausea, chill, and vomits, which can be paired with heavy sweating, dizziness, and headache.

One of these parasites is the tachinid fly larvae that can be found inside the abdomen of foraging females.
