Dianthidium
Pebble bees, resin bees
Dianthidium is a genus of solitary bees in the family Megachilidae, commonly known as pebble bees or resin bees. The genus comprises at least 20 described species in North America. These bees are distinguished by their use of plant resins in nest construction, gathering resins from various plant sources to build and seal their nest cells. They are cavity-nesting bees that utilize pre-existing hollows such as beetle borings in dead wood or hollow twigs. Dianthidium species are important pollinators and serve as hosts for parasitic wasps in the family Leucospidae.

Heriades
Armored Resin bees
Heriades is a genus of solitary bees in the family Megachilidae, comprising more than 130 species worldwide. These small, typically black bees are notable for nesting in pre-existing wood cavities and using plant resin to construct and seal nest cells. The genus spans eight subgenera with distributions across all continents; in North America, roughly 25 species occur, though only three are native east of the Rocky Mountains. Several species, particularly Heriades truncorum, serve as important research models for studying bee sexual communication, urban ecology, and pesticide effects.
