Help collect data

There are many questions we still need to answer about bees and you can contribute to efforts to gather data to answer these questions.

Honey bees

If you are a beekeeper, help us monitor mite loads by participating in Mite Check 

Bumble bees

If you live in or want to visit the Twin Cities, help us monitor bumble bee communities by participating in the MN Bumble Bee Survey

If you are anywhere in MN, you can help us monitor bumble bees by taking a class and adopting a bumble bee route for the MN Bee Atlas

If you are anywhere in North America, pick up your camera and share photos of bumble bees with the Bumble Bee Watch app for you phone or web app.

Cellophane bees

Keep your eyes open for Colletes inaequalis! Researchers at the University of Minnesota are studying Colletes (also known as cellophane bees) and we need your help identifying nesting locations in Ramsey, Hennepin, Washington, Dakota, and Anoka counties in Minnesota. Help us find cellophane bees as they make their nests in mid April to mid May.

What to look for:

  • About the same size as honey bees
  • Heart-shaped faces
  • Mostly found in sparsely vegetated areas
  • Nest mounds resemble ant nests but have larger entrance holes
  • Nest in groups on south-facing, sandy slopes

Piles soil along sandy slope

Piles in sandy soil with wide openings

Share your finds. Think you've found Colletes? Take pictures of the bee and the nest, and record your observation in iNaturalist. If you think you've found a nest but you don't see any bees, please take a photo and send it along with location info to broka028@umn.edu.
