Abstract: Plastic waste pervades the global landscape. Although adverse impacts on both species and ecosystems have been documented, there are few observations of behavioral flexibility and adaptation in species,
especially insects, to increasingly plastic-rich environments. Here, two species of megachilid bee are described independently using different types of polyurethane and polyethylene plastics in place of natural materials to construct and close brood cells in nests containing successfully emerging brood.

The plastics collected by each bee species resembled the natural materials usually sought; Megachile rotundata, which uses cut plant leaves, was found constructing brood cells out of cut pieces of polyethylene-based plastic bags, and Megachile campanulae, which uses plant and tree resins, had brood cells constructed out of a polyurethane-based exterior building sealant. Although perhaps incidentally collected, the novel use of plastics in the nests of bees
could reflect ecologically adaptive traits necessary for survival in an increasingly human-dominated environment.

BLOG STATS As of 01.29.2017 onward have been counting the number people who have read each post. WHY CUT PLASTIC About 100 million tons of plastic are produced each year and much of it is used to make one-use, disposable items. Because plastic doesn't biodegrade these items, though only used for moments can last for decades, centuries, possibly forever. We are creating ever lasting rubbish in unsustainable amounts. It is polluting the environment, maiming even killing animals, poisoning fish and may be poisoning us.
