This description is written clearly and is not very long or encyclopedic in tone. It covers basic kinds of solitary bees: carpenter, miner, cuckoo, leaf-cutter, and mason.

There is no worker class among solitary bees, but only fully developed males and females. Each female builds a nest in a protected place. Although many nests may be found close together each female solitary bee provides for her own young and gathers her own food. Like all wild bees, solitary bees are chiefly valuable as pollinators of plants.
