A Quest for Bumble Bee Nests

We know bumble bees have three basic needs:
  1. Food, free from pesticides, in the form of nectar and pollen
  2. Nest sites
  3. Overwintering sites

Of these three habitat needs, we know very little about bumble bee nesting requirements. Bumble Bee Watchers already provide valuable insight into the needs of bumble bees by submitting observations of bumble bees and also observations of nest sites on Bumble Bee Watch . However, nests can be cryptic, often tucked into grass tussocks or in old rodent burrows, and therefore are rarely documented. Researchers at York University have endeavored to learn more about this missing link. To do this, they are enlisting the help of volunteers to document nest sites, as well as detection dogs, which will be trained to sniff out nests.
Submit Your Sightings!

Spring has sprung, and you know what that means: bumble bee sightings! We are eager to see and hear about your newest sightings, so please make sure to submit to Bumble Bee Watch .
