Response Statement - Rusty-patched Bumble Bee

This species, which has a distinctive color pattern, was once commonly found throughout southern Ontario. Active searches throughout its Canadian range have detected only one small population over the past seven years which suggests a decline of at least 99% over the past 30 years.  It is threatened by disease, pesticides, and habitat fragmentation, each of which could cause extirpation in the near future.
