分舌花蜂科( Colletidae )又称穴泥蜂科是蜂族的一个科，通常被称为作为泥水匠蜜蜂或聚酯蜜蜂，由于平滑墙与它们的口器应用巢细胞分泌物的方法统称，这些分泌物干成玻璃纸像衬。分舌花蜂科有5亚科，54属，2000种以上，它们都明显孤立，尽管在许多巢聚合。

The Colletidae are a family of bees, and are often referred to collectively as plasterer bees or polyester 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. The five subfamilies, 54 genera, and over 2000 species are all 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 crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop.
