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 ...
Solitary bees, such as M. campanulae, do not form colonies. While social insects (ants, yellow jackets, honeybees) work in colonies, leafcutter and resin bees work independently building nests. [11] Similar to honeybees, female bees perform nearly all essential tasks of brood rearing.
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]
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. [1]
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.
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 ...
Bees of the genus Ptilothrix are solitary. Unlike honeybees or other eusocial bee species, the members of Ptilothrix do not form a hive or have division of labor of individuals. Females nest individually in hard-packed soil and oviposit eggs into brood cells provisioned with masses of pollen and nectar, which provide nutrients for their offspring.
