Colletidaeとは 意味・読み方・使い方

Colletidae is a family of bees, and are often referred to collectively as plasterer bees, due to the method of smoothing the walls of their nest cells with secretions applied with their mouthparts; these secretions dry into a cellophane-like lining. There are 5 subfamilies, 54 genera, and over 2000 species, all of them evidently solitary, though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa) that otherwise characterizes most bees, and instead carry the pollen in their crop. These groups, and in fact most genera in this family, have liquid or semi-liquid pollen masses on which the larvae develop.
