A leaf-cutter bee showing abdominal scopa. Megachilidae is a cosmopolitan family of mostly solitary bees.Characteristic traits of this family are the restriction of their pollen-carrying structure (called a scopa) to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families), and their typically elongated labrum.

The genus Megachile is a cosmopolitan group of solitary bees, often called leafcutter bees or leafcutting bees; it also includes the called resin bees and mortar bees. While other genera within the family Megachilidae may chew leaves or petals into fragments to build their nests, certain species within Megachile neatly cut pieces of leaves or ...
Northern colletes are solitary bees, though females may nest in what are termed aggregations – sites where the bees nest close together, but do not form colonies as social bees do. [1] They nest underground in soft (often sandy) soil, digging burrows up to 20 times their body length. [ 2 ]
Andrena prunorum, otherwise known as the purple miner bee, is a species of solitary bees in the family Andrenidae. [1] It is commonly found in the continental United States as well as much of North and Central America. [2] [3] Andrena prunorum is a spring-flying, ground-nesting bee that serves as a ubiquitous generalist in ecological settings ...
Unlike honey bees or bumblebees (Bombus), Osmia species are solitary; every female is fertile and makes her own nest, and no worker bees for these species exist. [1] Eastern snail shell mason bee (Osmia conjuncta) Hornfaced bee (Osmia cornifrons) When the bees emerge from their cocoons, the males exit first. The males typically remain near the ...
These are solitary bees and do not live in colonies and do not overwinter as adults. They nest in clay-sandy soils, especially in loess hills and soft-rock cliffs. [ 4 ] Like many other solitary bees, they can often be found nesting in dense aggregations, [ 4 ] sometimes numbering many tens of thousands of nests.
Solitary bees, such as leafcutters, do not form colonies. Unlike social insects (ants, yellow jackets, honeybees), leafcutters work alone building isolated nests. [ 2 ] Similar to honeybees , female bees perform nearly all essential tasks of brood rearing.
