How many different types of native bees are there in Minnesota?

"About 500," guesses researcher Dan Cariveau. He doesn't know for sure, but it's one of many questions drawing him from Rutgers University in New Jersey to the 

Cariveau will join other bee researchers in the new Bee and Pollinator research building which breaks ground in August. 

He's the first researcher at the U to focus solely on native bees.

"The state of Minnesota has a lot of interest in figuring out which native bees are here, and how important they are to agriculture and native plants. Very few states at that level of interest," Cariveau told MPR News host Tom Weber.

One bee Cariveau is keen on understanding is the rusty-patched bumblebee. The bee was once commonly seen in Minnesota, but today is nearly extinct. 

"Bees need a specific type of habitat. They all need flower products. Pollen for their young and for themselves,  nectar for themselves. They need good flora resources," he said.  

"I'm interested in what kind of habitat they need and how can we create and build a habitat for these bees to help increase their populations," Cariveau added.

85 percent of plants rely on animals to move their pollen around, and bees are responsible for a majority of that job.

A new researcher is joining the U of M Bee Lab to try and answer many of the questions we don't know about native bees in Minnesota.

There will be a groundbreaking later this summer for a new Bee and Pollinator Research building on the University of Minnesota-St. Paul campus. The center will be a hub of study on bees and will attempt to find out why there have been problems in recent years with some bees, like honeybees, dying off.
