Chalybion is a genus of blue mud dauber wasps in the family Sphecidae. Chalybion species nest in a wide range of natural and artificial cavities such as holes in wood, walls, plant stems, etc., where they typically provision their brood cells with paralyzed spiders. They also reuse old nests of other wasps like Trypoxylon and Sceliphron.
