Honey bees are fond of strawberries, but solitary bees are always present

(Georg-August-Universität Göttingen) While honey bees might prefer strawberry fields over flowering oilseed rape, honey bees are less common in among strawberries when the oilseed rape is in full bloom. In contrast, solitary wild bees, like mining bees, are constantly present in the strawberry fields. “Wild bees are therefore of great importance for the pollination of crops… our results also show that wild bees in the landscape should be supported by appropriate management measures.”

Tall hemp attracts more bees

(Boulder Weekly) The Cornell team collected bees at 11 hemp farms in central New York in the summer of 2018. Their findings show that hemp plants at least 2 meters tall attract nearly 17 times the number of bee visits compared to short plants. The number and species of bees increased proportionally with plant height, with 16 different bee varieties making cannabis pit stops.

Gulf Coast bee, Delaware firefly move toward endangered species protection

(Center for Biological Diversity) The U.S. Fish and Wildlife Service announced today it will move forward with considering Endangered Species Act protection for the Gulf Coast solitary bee and Bethany Beach firefly. Both coastal species face increasing threats from climate-driven sea-level rise, unchecked coastal development and pesticides.

Wild pollinators get the job done in the pumpkin patch

(Entomology Today) Commercial pumpkin growers routinely rent honey bees so they have enough insects to pollinate their crops, but a new study found that wild bumble bees and squash bees could easily handle the pollination required to produce a full yield of pumpkins. “When we multiplied the number of visits times how much pollen they were depositing, we were blown away to find that bumble bees and squash bees combined were doing more than 10 times the pollination that was necessary.”

Study sheds light on ‘overlooked’ bee species

(Phys.org/Angli Ruskin University) The U.K.’s first citizen science project focusing on solitary, ground-nesting bees has revealed that they nest in a far broader range of habitats than previously thought. “This information on nesting behaviour is highly valuable because it puts us in a better position to provide advice to land owners on how to manage their land sympathetically in order to protect these important, ground-nesting solitary bees.”

Fish and Wildlife Service announces it will review petition to list Mojave poppy bee as endangered

(Center for Biological Diversity) The U.S. Fish and Wildlife Service announced today it will consider Endangered Species Act protection for the Mojave poppy bee. Today’s positive finding comes in response to a petition filed in 2018 by the Center for Biological Diversity. Although it once thrived across much of the Mojave Desert, the quarter-inch-long, yellow-and-black bee is now only found in seven locations in Nevada’s Clark County. The bee is tightly linked to the survival of two rare desert poppy flowers. The bee has disappeared as those plants have declined, as well as facing ongoing threats from grazing, recreation and gypsum mining.
