Urban bees use plastic to build hives

Thursday, May 1, 2014

Scott MacIvor and Andrew Moore published their findings in Ecosphere in December. By observing trap nests in Toronto, they discovered that the Megachile campanulae hives, traditionally made with plant and tree resins, had bits of polyurethane exterior house sealant incorporated into them. And the hives of Megachile rotundata (leafcutter bees), usually made with leaves, contained chewed-up pieces of plastic bags.
