Happy National Pollinators Week. It’s well worth celebrating here in Wisconsin, where more than 500 native wild bee species play an essential role in pollinating the state’s food crops, and farmers are becoming more interested in learning about all the different kinds that buzz around their fields each season.

CALS entomology graduate student Rachel Mallinger knows a lot about the native bees of the badger state. Mallinger, who works in the lab of CALS entomology professor and Great Lakes Bioenergy Research Center sustainability scientist Claudio Gratton, has developed an online bee identification guide to benefit farmers, landowners and curious citizens.
