About
The Rusty Patched Bumblebee is a critically endangered species that has declined sharply due to habitat loss, pesticide use, disease, climate change, and the loss of diverse wildflower meadows it depends on. Once common in grasslands and prairies across eastern and midwestern United States and parts of Canada, it now survives in scattered, fragmented populations.
Despite this decline, the Rusty Patched Bumblebee plays a crucial ecological role in ecosystems as a highly effective pollinator, especially for wildflowers and agricultural crops like tomatoes, cranberries, and blueberries, using a behavior called “buzz pollination” that many plants depend on.
Due to its sensitivity to environmental change, the Rusty Patched Bumblebee also serves as an important indicator species, meaning its decline signals broader problems in ecosystem health and biodiversity loss.
