Bombus morio is one of the few bumblebee species found in South America. These bees reside mainly in the forests of Brazil, nesting on the surface of the ground. They are one of the biggest species of bumblebee and are important pollinators. They are one of the few species of bees that exhibit buzz pollination to collect pollen from the flowers.
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. Out of these bumble bees, only six are known to exist within Brazil, and they all belong in the same subgenus of Fervidobombus. Five of these six are very closely related, but the sixth, the Bombus morio, belong to a distinctive clade. Phylogenetic analysis has shown that the Bombus morio, are exclusively distinct.
There are known to be around 250 Bombus species. Most of these species occur in the northern climate zones of America and Eurasia. Only a few species reside in the southernregions, and one those is the Bombus morio. These bees are dependent on the forest, and reside in temperate regions of Brazil.
They reside in the mid-lands and are principally surface nesters. However, their nests can also be found below ground.
The Bombus morio is a bumble bee, and thus shares certain features with other bumble bee species. They have three main body parts: head, thorax, and abdomen. The difference between female and male genders can be distinguished by the number of thorax segments. For the female, there are 6 segments, while the male holds 7 segments. Additionally, the males have 12 segments on their antenna, while the females have 13. The females also have pollen baskets, a rimmed segment with long hairs on their back legs, which are used to carry pollen back to the nest, while males do not have pollen baskets.
It is very important for the bumble bees to have bodily homeostasis over their body. However, the Bombus morio do not have a rectal pad. Instead, the excretion system in the Bombus morio, consisting of the Malpighian tubles, ileum, and rectum, gives the bees an efficient method of keeping homeostasis. An analysis of these organs showed that the Bombus morio Malpighian tubles are made up of two cell types, and the ileum four types. The Malpighian tubles are significant for excretory features by throwing out excess and unnecessary solutes. Ileum, on the other hand, has the function of balancing the ion, water, organic compounds, and protein balance in the body. Together, the two organs work together to achieve homeostasis within the Bombus morios bodies despite the lack of rectal papillae.
