Which of the following is identified as an endangered species of bumblebee?

The rusty patched bumblebee is recognized as an endangered species due to significant population declines driven by factors such as habitat loss, pesticide exposure, climate change, and diseases. Conservation efforts are ongoing to protect this species, as it plays a crucial role in pollination, contributing to the health of ecosystems and agriculture. The identification of the rusty patched bumblebee as endangered highlights the importance of biodiversity and the specific threats facing certain bee species, which are vital for pollination and ecosystem stability.

Other bee species listed, like the honeybee, carpenter bee, and leafcutter bee, may face their own challenges but are not listed as endangered and are generally more adaptable. Focusing on the rusty patched bumblebee emphasizes the need for targeted conservation actions and increased awareness of the decline in specific pollinator populations.
