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.
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 ]
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.
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 ...
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.

Carpenter bees sometimes are mistaken for bumble bees, which have a similar appearance. A carpenter bee is about ¾ to 1-inch long and nest in excavated tunnels in wood.
Melittids are typically small to moderate-sized bees, which are well known for their specialist and oligolectic foraging habits. [1] Melittids are strictly solitary and they nest in burrows that they dig in soil or sand. [9] All females can reproduce and tend to emerge from the ground some days before the male.
So the car drove away with 20,00 bees in tow — and they didn't let up the chase for two days. "I have been beekeeping for 30 years and I have never seen a swarm do that.
