Bees in the family Megachilidae carry pollen on the underside of their abdomen. Unlike honeybees, they do not have pollen baskets on their hind legs. [13] Most bees in the genus are small to medium in size, although M. pluto at 38 mm is regarded as the largest bee in the world. [14] Many bees in the genus are referred to as leafcutters.
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.

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 ]
Like many other solitary bees, they can often be found nesting in dense aggregations, [4] sometimes numbering many tens of thousands of nests. In parts of the west European range of the species, Colletes hederae are frequently parasitized by the larvae of the meloid beetle Stenoria analis , [ 2 ] which feed on the supply of nectar and pollen ...

[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 ...
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 ...
