The Life Cycle of Mason Bees

August 13, 2024

Mason bees are some of the most efficient pollinators.

 

Often overlooked in the shadow of their more famous honeybee cousins, Mason bees have the ability to pollinate 95% of the flowers they visit.

 

With just a few mason bees, one can significantly boost the productivity of their fruit trees, flowers, and vegetables.

 

These tiny allies bring great value to the garden.

 

However, in order to truly appreciate their importance, it’s important to understand their fascinating life cycle.

 

We’ll take you through the journey of a mason bee, from its early spring emergence to its crucial role in pollination, and finally, how it prepares for the next generation.

 

So, without further ado, let us get going.

 

The Basics of Mason Bees

 

Mason bees are small, friendly bees that are amazing for your garden.

 

Unlike honeybees, they don’t live in hives or make honey; each female mason bee works on her own to build a little nest, usually in a small hole or tube. They get their name because they use mud, like a mason, to seal up their nests.

 

Even though they work alone, mason bees are super pollinators, visiting and pollinating way more flowers than honeybees can. They're easy to have around and are a great way to boost your garden’s productivity.

The Mason Bee Life Cycle

 

Early Spring: Emergence

 

In early spring, when fruit trees start to bloom, mason bees wake up from their winter rest. Male bees come out first, hanging around potential nesting spots while waiting for the females. When the females emerge, they quickly mate with the males. After mating, the females start the important job of finding places to lay their eggs.

 

Mating and Nesting

 

Female mason bees look for good nesting spots, like hollow tubes or natural holes in wood. These spots are where they’ll lay their eggs. Gardeners can help by providing nesting blocks or tubes in a sheltered area. This way, mason bees have a safe place to create their nests.

 

Egg-Laying and Larvae Development

 

Once a female finds a good nesting spot, she fills each nest cell with pollen and nectar to feed her eggs. After laying an egg in each cell, she seals it with mud. The larvae that hatch eat the food in their cell, grow, and then spin a cocoon around themselves.

 

Summer: Development and Dormancy

 

Throughout the summer, the larvae continue their development within the safety of their mason bee cocoons. They transform into pupae and eventually into adult bees, though they remain dormant inside the mason bee cocoons. This period of dormancy is critical, as it allows the bees to conserve energy and complete their development, preparing them for emergence the following spring.

 

Autumn and Winter: Hibernation

 

As fall comes, bees hibernate inside their mason bee cocoons throughout the winter.

 

To protect them, gardeners can make sure their nesting sites are safe from cold and wet conditions. Keeping nesting blocks in a dry, protected place helps ensure the bees will be ready to come out in the spring.
