Morrison’s Bumble Bee came to my attention today in two ways. First, this photo–which I posted on inaturalist last August along with a tentative identification–was confirmed today as truly being Morrison’s Bumble Bee. Second, I read the news that made this sighting all the more precious: the US Fish & Wildlife Service is now considering Morrison’s Bumble Bee for protection under the Endangered Species Act. Numbers have declined by up to 75% and the bee has completely disappeared across much of its range.
According to the Xerces Society, “The Morrison bumble bee historically occurred across much of the western U.S. . . . in grasslands, sagebrush steppe, and woodland edges. It has co-evolved with local plants for thousands of years and is a super-pollinator, contributing to the stability of our wildlands and agricultural systems.” The bee’s decline is attributed to the usual culprits–“habitat loss and degradation, overgrazing, climate change, pesticides, diseases, and competition with honey bees.”
What can we do? Other than not using pesticides (please!), just plant more flowering plants. The bee in my photo is on Rocky Mountain Bee Plant, a fabulous native annual. Bumble bees use all kinds of flowering plants, including milkweed.
In case you like to take photos of plants and animals, check out inaturalist. It is a fun way to engage with the natural world and with other like-minded folks. Upload photos of any living thing, suggest an identity or allow inaturalist to do that for you. For me, this is a fun way to learn more about everything!
