Do Masonry Bees Build Nests
Yes, masonry bees do build nests.
They are named for their habit of using mud or other “masonry” products to construct their nests.
These nests are made in naturally occurring gaps such as cracks in stones or other small dark cavities.
Some species of masonry bees preferentially use hollow stems or wood holes made by wood-boring insects.
Overall, masonry bees are solitary and each female makes her own nest, gathering pollen and nectar to create a provision mass for her eggs.
Did You Know?
1. Masonry bees, also known as mason bees, are solitary pollinators that prefer building their nests in pre-existing holes, such as empty snail shells or abandoned insect burrows.
2. Unlike honeybees, masonry bees do not produce honey or beeswax. Instead, they utilize mud to construct their nests, hence the name “masonry bees.”
3. Masonry bees are highly efficient pollinators, capable of visiting up to 2,000 flowers per day. Their primary objective is to collect pollen for their offspring, making them vital contributors to ecosystem health.
4. These bees do not live in colonies or hives like honeybees. Instead, each female masonry bee creates her own nest, lays eggs, and provisions them with pollen before sealing the nest with mud.
5. One fascinating fact about masonry bees is that they have been proven to be excellent artists! While constructing their nests, they strategically arrange materials like pebbles or petals outside their homes, creating visually appealing patterns that serve as clues to potential mates.
Masonry Bees And Their Nest-Building Techniques
Masonry bees, scientifically known as Osmia in the genus Osmia, are part of the Megachilidae family and are esteemed for their unique nesting habits. They have earned the name “masonry” bees due to their remarkable ability to construct nests using mud or other similar materials. These nests are created in naturally occurring gaps such as cracks in stones or other small dark cavities. Some species of masonry bees, however, exhibit a strong preference for hollow stems or wood holes made by wood-boring insects.
One interesting characteristic of masonry bees is their nesting technique. Unlike social bees, Osmia species are solitary bees, and each female is fertile and constructs her own nest. These bees do not excavate their own nests; instead, they utilize existing narrow gaps and naturally occurring tubular cavities, like hollow twigs or abandoned nests. The material used for constructing the nest cell can vary, ranging from clay, mud, grit, to chewed plant tissue. In a captivating display of creativity, certain species, such as O. avosetta, line their nest burrows with delicate and colorful flower petals.
Natural Habitat And Nesting Preferences Of Masonry Bees
With over 300 species found across the Northern Hemisphere, masonry bees thrive predominantly in temperate habitats within the Palearctic and Nearctic realms. These bees are well adapted to various environments and can be observed in diverse locations, from lush meadows to urban gardens.
When seeking suitable nesting sites, female masonry bees inspect several potential nests before settling on one. They carefully evaluate each option, considering factors such as accessibility, protection from predators, and proximity to reliable sources of pollen and nectar for provisioning their nest.
While some species favor readily available nesting locations like cracks in stones or small crevices, others display a preference for specific materials or structures. Hollow stems and wood holes created by wood-boring insects, for example, are particularly appealing to certain masonry bees. By exploiting existing gaps and cavities, these resourceful bees can efficiently construct their nests without the need to excavate a new burrow.
The Diversity Of Osmia Species In The Northern Hemisphere
The genus Osmia encompasses an impressive diversity of species, showcasing a wide array of colors and morphological variations. The metallic green or blue hues that adorn many Osmia species are a striking sight in nature. However, it is noteworthy that not all masonry bees possess these vibrant colors; some species can exhibit blackish or rust-red hues, adding to the charm and uniqueness of these bees.
To better understand the incredible diversity found within the Osmia genus, it is important to note that the majority of these species reside in temperate habitats throughout the Palearctic and Nearctic realms of the Northern Hemisphere. This widespread distribution allows masonry bees to thrive in a range of environments, adapting to the specific conditions present in their respective habitats.

Solitary Behavior And Reproduction Of Masonry Bees
One of the defining characteristics of masonry bees is their solitary behavior. Unlike social bees, such as honeybees and bumblebees, masonry bees do not have worker bees. Each female masonry bee is fertile and responsible for constructing her own nest. This solitary lifestyle allows masonry bees to exhibit fascinating behaviors and engage in unique reproductive strategies.
The life cycle of masonry bees begins as the males emerge from their cocoons and wait near the nest sites for the arrival of the females. Once the females emerge, they mate with one or several males until the males eventually die. Following the mating process, the females search for suitable nesting sites to prepare for reproduction. Their nesting behavior involves gathering pollen and nectar, which they collect and store as provisions for their offspring.
- Key characteristics of masonry bees:
- Solitary behavior
- No worker bees
- Life cycle:
- Males emerge from cocoons and wait for females
- Females mate with one or several males

Nest Construction And Provisioning Of Masonry Bees
The construction of the nest and provisioning process carried out by masonry bees is remarkable. After a female masonry bee gathers a sufficient provision mass of pollen and nectar, she lays an egg on top of the mass. The female meticulously seals the cell to ensure the safety and nourishment of her future offspring. This process is repeated for each nest cell, with the female carefully selecting and provisioning multiple cells throughout her nesting site.
The material used to construct the nest cell varies among masonry bee species. Clay, mud, grit, or chewed plant tissue may be used, depending on the availability and suitability of the resources in the environment. These materials are carefully manipulated and shaped by the females to form a protective structure that safeguards the developing larva until it is ready to emerge as an adult bee.

Frequently Asked Questions
Do mason bees hive?
Unlike honey bees, mason bees do not hive in traditional bee hives. Instead, they prefer to nest in tubes or holes, making them quite unique and different from other bee species. This nesting habit makes mason bees low-maintenance and great companions to have. Moreover, their preference for tubes or holes means that you don’t need any fancy equipment or elaborate hives to raise them, making them an easy and hassle-free option for bee enthusiasts.
How do you get mason bees to nest?
To attract mason bees to nest, it is essential to provide them with suitable conditions. Firstly, having a clay-like mud source within proximity, ideally within 50 feet, is crucial as mason bees use mud to construct their nests. Additionally, the placement of the nest is vital—choose a location within 200-300 feet of pollen-rich plants and trees that bloom in spring. By ensuring the bees have easy access to their food source, they can save energy and time that would otherwise be spent foraging for food. With these elements in place, you can create an inviting environment for mason bees to nest and thrive.
Do mason bees lay eggs?
Yes, mason bees do lay eggs. These remarkable bees lay their eggs in the spring, and after a period of time, the eggs hatch into larvae. However, these larvae do not immediately emerge from their cocoons as adults. Instead, they wait until the following spring to emerge, mate, and build nests of their own. Despite their short lifespan of six to eight weeks, a female mason bee can lay up to 30 eggs during her lifetime, ensuring the continuity of their species.
Where do you put a mason bee nest?
To provide an ideal habitat for mason bees, it is recommended to place their nest 6 to 7 feet above the ground, ideally under the eave of a building such as your house, garage, or shed. This location offers protection from the elements and provides a safe and convenient shelter for these solitary pollinators. By situating the mason bee house here, you create an environment that promotes their pollination activities and contributes to the overall ecosystem’s well-being.
