This survey focuses on bumble bee populations in the Twin Cities Metro area, one of the last homes of the endangered rusty patched bumble bee.
Several bumble bee species appear to be in decline. Bombus affinis and Bombus terricola are rarely seen in Minnesota. Bombus fervidus and Bombus pensylvanicus also are in decline. Multi-year surveys are needed to establish current population statuses and gauge variability between years. Plus, chasing bees through fields of flowers is a great way to spend a summer day.
