(Twitter, Elaine Evans @fuzzybumblebee) Why are grasses in pollinator mixes if bees don’t feed on them? Besides food for endangered butterflies like Dakota skippers, deep roots for water filtration & soil retention, native grasses makes great bumble bee nesting material.

(The University of Vermont) Researchers discovered that two well-know RNA viruses found in honey bees were higher in bumble bees collected less than 300 meters from commercial beehives. And they detected viruses on 19% of the flowers they sampled from sites near apiaries.
(Twitter, Sheila Cola @SaveWildBees) “We are using trained dogs to find bumblebee nests because they are so dang hard to find, but important to find for conservation. Wish us luck!”
(Xerces Society) To help further our understanding of, and conservation efforts for, bumble bees, The Xerces Society has launched the Nebraska Bumble Bee Atlas. This community science project offers locals the opportunity to work alongside researchers to collect data that will shed light on the distribution, status, and habitat needs of Nebraska’s bumble bees.
(JD Supra/Nossaman LLP) The Commission voted 3-1 that listing four subspecies of bumble bee may be warranted under the California Endangered Species Act (CESA). The decision was made after the Xerces Society, Center for Food Safety, and Defenders of Wildlife filed a petition to list the Crotch bumble bee, Franklin’s bumble bee, Suckley cuckoo bumble bee, and western bumble bee as endangered species.
(UC ANR) Dr. Robbin Thorp, a global and legendary authority on bees and a distinguished emeritus professor of entomology at the University of California, Davis, passed away Friday, June 7 at his home in Davis, surrounded by family. He was 85. A tireless advocate of pollinator species protection and conservation, Dr. Thorp was known for his expertise, dedication and passion in protecting native pollinators, especially bumble bees, and for his teaching, research and public service.
(UC Riverside) “Our study is the first to look at diet during this stage where queen bumbles are trying to start a nest, and to show that the diets they have access to impact how quickly they can transition to having helpers.” And without a variety of pollens available, the queens are constrained to fewer options, some of which appear to be bad for them.
(Imperial College London) Realistic exposures caused bumble bee to fly significantly shorter distances and for less time, reducing the area in which colonies can forage for food by up to 80 percent. Intriguingly, exposed bees seemed to enter a hyperactive-like state in which they initially flew faster than unexposed bees and therefore may have “worn themselves out”.
