Bowl traps are little plastic bowls, in blue, yellow, and white, that are filled with soapy water and set out to catch bees. In a new article published in May 2020 in Annals of the Entomological Society of America, a group of researchers points out that bee bowls often don’t catch a representative sample of the bees seen on nearby plants, and they urge the bee research community to work toward developing new methods for monitoring bees.
