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.
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 ]
In contrast, all males die in the fall. Overwintered females found new nests in April. Their offspring emerge in June, and proceed to found nests of their own by the end of the month. Males tend to emerge from the first cells built, and females emerge shortly thereafter. [8] Males in the laboratory live on average about 14.88 days. [10]
This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees.
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.
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 ...
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.
