Native Flowers for the Rusty Patched Bumble Bee
About this community science project
We partner with community scientists to grow and inventory host plants for the Rusty Patched Bumble Bee. By uploading photos of plants and bees to iNaturalist, you can contribute to research to assess and conserve habitat for the Rusty Patched Bumble Bee and other important pollinators.
The Rusty Patched Bumble Bee
This native pollinator was once common in the Chicago area and 30 other states and provinces in the Midwestern and Eastern United States and Canada. Its population has declined over 87% in the last 20 years because of pathogen spillover, habitat loss, pesticide use, and climate change. Bumble bees are important pollinators for native flowers and the crops that we eat, and they provide many benefits for people and the ecosystem.
You can bee a host!
Native wildflowers organically grown in residential yards and urban green spaces can provide significant foraging resources for pollinators. The Rusty Patched Bumble Bee relies on 38 flowering host plants, many of which are common in yards. You can create habitat in your yard by growing host plants that bloom throughout the season, eliminating pesticide and chemical use, and letting sticks and leaves remain.
Help us assess and create habitat by:
• Growing host plants
• Uploading photos of plants and bees to iNaturalist
Rusty Patched Bumble Bee Identification:
The Rusty Patched Bumble bee can be identified by a thumbtack shaped black marking and a distinctive rusty colored back on their backs.
