Cellophane or Polyester Bee- Colletes
Polyester bees are a diverse group of solitary ground nesting bees represented by over 100 North America species. They resemble and share a similar lifestyle to mining bees and some sweat bees.
The females will often nest in large aggregations making shallow brood cells only 4 to 6 inches deep. These bees line their brood cells with completely waterproof cellophane-like substance allowing them to nest in very wet areas. This material has been studied as a natural plastic substitute that can decompose in as little as five years. The polyester bee provisions her eggs with a liquid form of nectar and pollen.
