Urban bees using plastic to build hives

“Plastic waste pervades the global landscape,” said MacIvor.Although researchers have shown adverse impacts of the material on species and the ecosystem, few scientists have observed insects adapting to a plastic ugg boots uk rich environment, he said.”We found two solitary bee species usin ugg boots uk g plastic in place of natural nest building materials, which suggests inno ugg boots uk vative use of common urban materials.Figuring out that the bees were using plastics in place of natural materials took some detective work by University of Guelph’s Andrew Moore.Moore analysed a grey “goo” that MacIvor discovered in the nests of one kind of bee, Megachile campanulae, which uses plant resins to build its nests.”Scott thought it might be chewing gum originally,” Moore said.M campanulae was occasionally replacing plant resins with polyurethane based exterior building sealant, such as caulking, in its brood cells created in a nest to rear larva, researchers said.They also discovered another kind of bee, Megachile rotundata, an alfalfa leafcutter, was using pieces of polyethylene based plastic bags to construct its brood cells.The glossy plastic replaced almost one quarter of the cut leaves normally used to build each cell.Markings showed that the bees chewed the plastic differently than they d ugg boots uk id leaves, suggesting that the insects had not incidentally collected plastic.”The plastic materials had been gathered by the bees, and then worked chewed up and spit out like gum to form something new that they could use,” Moore said.In both cases, larvae successfully developed from the plastic lined nests. In fact, the bees emerged parasite free, suggesting plastic nests may physically impede parasites, according to the study. PTI
