For the very first time, scientists have documented a wild bee nest built entirely out of plastic trash. The plastic nest was discovered during the 2017-2018 summer season in the rural farmlands of San Juan, Argentina by a team led by Mariana Allasino of the National Agricultural Technology Institute. This is the first time worldwide that plastic has been revealed to be the sole material used in the total construction of a bee nest. "The use of plastic as the only resource for the construction of the nest could be associated with the preference of this material over natural ones. Some evidence shows that the use of synthetic materials in nesting could bring adaptive advantages," the researchers wrote in a study published in the Apidologie journal.
