Abstract - Colletidae are unique among bees for certain aspects of their nesting biology. In this review, attributes of colletid nesting are evaluated and discussed in light of a novel phylogenetic hypothesis for the family. Some predictions made about evolution of certain traits, such as the cocoon-spinning behavior of Diphaglossinae, are confronted with phylogenetic evidence. The cellophane-like cell lining of Colletidae is a synapomorphy of this bee family, formed by polyester and characterized for being thick and strong, waterproof, and insoluble in different solvents. Historical developments towards the understanding of nature of the cell lining applied by colletids are summarized along with an account of diversity of some aspects of nesting of these bees.
