The flowers are pollinated by a number of native bee species, especially genus Osmia.

She published a monograph on the Osmia genus.

Osmia females like to nest in narrow holes or tubes, typically naturally occurring tubular cavities.

Mason bee is a common name for species of bees in the genus Osmia, of the family Megachilidae.

Dioxys is a brood parasites of Megachile, Anthidium and Osmia.

Main hosts are Osmia, Eumenes and Odynerus species.

The flowers of this penstemon are pollinated by bees of genus Osmia, which feed on their nectar.

Osmia Identification Guide (female)

The North American bees of the genus Osmia (Hymenoptera: Apoidea).

Most Osmia species are found in places where the temperature drops below 0 C for long durations, like Canada, and they are well-adapted to cold winters.

The flowers bloom in April and May and are pollinated by bees of the genera Anthophora, Bombus, and Osmia.

Neue Arten und Varietaten der Gattung Osmia Panz.

Mimulus lewisii is pollinated by bees (primarily Bombus and Osmia), which feed off of its nectar and transfer its pollen.

Osmia cornifrons, commonly known as the hornfaced bee, has been used commercially for several decades in Japan to pollinate apples, as it is now in the US.

The pale yellow flowers open in May and are visited by several species of bumblebees and solitary bees, including species from the genera Osmia and Anthophora.

Unlike honey bees (Apis) or bumblebees, Osmia are solitary; every female is fertile and makes her own nest, and there are no worker bees for these species.

According to Christopher O'Toole's The Red Mason Bee, Osmia rufa is a much more efficient pollinator of orchard crops than the honeybee.

Nest cavities are often linear, for example in hollow plant stems, but not always (snail shells are used by some Osmia, and some species will readily use irregular cavities).

The flowers are pollinated by several species of bees, including Ceratina nanula, Synhalonia fulvitarsis, Dioxys pomonae, Stelis pavonina, and many species of Osmia.

These orchids are mainly pollinated by some beetles (Oedemeridae and Lymexylidae family) and by Hymenoptera (genus Ceratina, Eucera and Osmia).

O. lignaria is a common species used for early spring fruit bloom in Canada and the United States, though a number of species of other Osmia are cultured for use in pollination.

Die Bienengattung Osmia Panz., als Erganzung zu Schmiedeknecht's 'Apidae europaeae', col. II, in ihren palaerctischen Arten monographisch bearbeitet.

They resemble small Osmia, but they are oligolectic (specialized on a few subfamilies of Asteraceae) and use resin from conifers, as well as plant fibers and sand, as cell wall material.

Some of the bee species that interact with R. flagellaris are mason bees (of the genus Osmia), leaf-cutting bees, cuckoo bees (of the subfamily Nomadine), and miner bees.

Osmia cornutaare also known as the builder bee, because when they build their nest in either the ground or structures that allow them to lay their eggs, it is usually the female who digs to find an adequate nest.
