The bumblebee is a small, fuzzy, and often overlooked creature that plays a critical role in the ecosystem.
These industrious insects are not only important pollinators of wildflowers and crops but also the exclusive pollinators of some rare and imperiled wildflowers.
They are also the only known pollinators of potatoes worldwide, making them essential for the world’s food supply.
Bumblebees are social bees that live in colonies of between 50 and 500 individuals.
Unlike most native bees, but like honey bees, bumblebees are social insects that live in colonies.
The vast majority of our native bees are solitary and don’t form hives or have queens.
Bumblebees are central place foragers, meaning they fly out from their nest to collect nectar and pollen from flowers within a radius of about 100 meters.
This makes them incredibly efficient pollinators, as they are able to visit more flowers in a shorter amount of time than solitary bees.
Despite their importance, bumblebee populations are declining due to habitat loss, pesticide use, and climate change.
By creating bee-friendly gardens and providing nesting sites, we can help support bumblebee populations and ensure their continued role as pollination powerhouses of the garden.
The Life and Times of Bumblebees
Bumblebees are fascinating creatures that play a crucial role in pollinating gardens and crops.
They are known for their fuzzy and plump appearance, and their distinctive buzzing sound as they fly from flower to flower.
But what do we really know about these pollination powerhouses? Let’s dive into the life and times of bumblebees.
From Birth to Flight: The Bumblebee Lifecycle
Bumblebees have a unique life cycle that starts with the queen bumblebee emerging from hibernation in early spring [1].
The queen will have spent the entire winter underground, using up reserves of energy stored as fat in her body.
When she first emerges, she feeds on flowers, drinking nectar to gain energy.
Once she has built up her strength, she will search for a suitable nesting site.
After finding a suitable location, the queen will start laying eggs, which will hatch into larvae.
The larvae will then pupate and emerge as adult worker bees.
These worker bees will take over the duties of foraging for nectar and pollen, and caring for the queen and future generations of bumblebees.
The colony will continue to grow throughout the summer, with new generations of workers and drones being produced.
In late summer, the queen will start to produce new queens and males. These new queens and males will mate, and the males will die soon after.
The new queens will then hibernate underground for the winter, ready to start the cycle anew in the following spring [2].
The Queens and Their Colonies
The queen bumblebee is the heart and soul of the colony. She is responsible for laying all the eggs that will hatch into workers, drones, and future queens.
The queen bumblebee is also responsible for choosing the location of the nest, and for defending it against predators and other threats.
Bumblebee colonies are relatively small compared to other bee species, with only a few hundred individuals at most [3].
However, they are highly organized and efficient, with each individual having a specific role to play in the colony.
The workers are responsible for foraging for food, caring for the young, and defending the colony against predators.
Winter Woes: Hibernation and Survival
Bumblebees face many challenges during the winter months.
As temperatures drop, food sources become scarce, and the bees must find a way to survive until spring.
Bumblebees have adapted to survive the winter by hibernating underground [4].
The queen will find a suitable location, such as an abandoned rodent burrow, and hibernate there until spring.
During hibernation, the queen will enter a state of torpor, in which her metabolic rate slows down to conserve energy.
This allows her to survive on the fat reserves she has built up during the summer months.
Bumblebees are also able to regulate their body temperature by shivering their flight muscles, which generates heat [5].
In conclusion, bumblebees are fascinating creatures that play a vital role in pollinating our gardens and crops.
From their unique life cycle to their highly organized colonies, bumblebees are a testament to the wonders of the natural world.
So next time you see a fuzzy bumblebee buzzing around your garden, take a moment to appreciate all the hard work they do.

Pollination is the process by which pollen grains from the male part of a flower (the stamen) are transferred to the female part of the same or another flower (the pistil), leading to fertilization and the production of seeds.
Pollination is essential for the reproduction of flowering plants and the production of many crops that humans rely on for food, such as tomatoes, blueberries, and peppers.
How Bumblebees Pollinate Plants
Bumblebees are one of nature’s most effective pollinators. They have a special adaptation that allows them to carry pollen from flower to flower.
When a bumblebee lands on a flower, it uses its strong jaws to grip the base of the flower and then vibrates its wings at a high frequency.
This vibration causes the flower to release a cloud of pollen, which sticks to the bumblebee’s hairy body.
The bumblebee then flies to another flower, transferring the pollen to the pistil and fertilizing the flower.
Buzz Pollination: A Bumblebee Specialty
Bumblebees are also unique in their ability to perform a special type of pollination called buzz pollination.
This is when a bumblebee vibrates its wings at a specific frequency to release pollen that is tightly held within a flower.
This type of pollination is particularly important for crops such as tomatoes, blueberries, and peppers, which rely on buzz pollination for efficient fertilization.
The Mutual Benefits for Bees and Blooms
Pollination is not only important for plants, but also for bees. Bees rely on the nectar and pollen from flowers for their survival.
Nectar is a sugary liquid that provides bees with energy, while pollen is a rich source of protein and other nutrients.
As bees collect nectar and pollen, they inadvertently transfer pollen from flower to flower, pollinating the plants and ensuring their continued survival.
In conclusion, the humble bumblebee plays a critical role in the art of pollination.
Their unique adaptations and behaviors make them one of nature’s most effective pollinators, benefiting both plants and bees.
So, next time you see a bumblebee buzzing around your garden, take a moment to appreciate the important work they are doing to keep our world blooming and thriving.
