Types of Bees: Native bees vs Foreign bees

Sometimes we forget that honeybees aren’t the only types of bees out there.

How many types of bees are there?

There are over 20,000 species of bees all over the world. In the U.S., scientists have found over 4,000 native species. Plants have evolved ways to attract and take advantage of their pollination and honey production services.

When we attribute a third of our food to bees, most of us think of honey bees. Yet, they are just a sliver of the entire bee pie. Without these other species, we would eliminate many of our fruits and vegetables.

Our beekeeping activities affect other beneficial insects in the environment. Hence, protected areas are set up to preserve the ecosystem for native bees. Our interest in honeybees compliments our need to understand other bee species.  

Going through all the native species would require an encyclopedic type of post, and this isn’t one of those. But, what are the most common types of bees? We’ll just go through some of the types of bees commonly found in yards and gardens.

But first, let’s differentiate between native and foreign species.

Native Bees

These unsung heroes are indigenous to the U.S. They are well suited to the climate and adapted to the native plant life, such as berries and squash. Often, they have a taste for a particular plant, with a very short list of alternatives. If that plant is cleared away, that species of bee could get extinct.

Take the Rusty Patched Bumblebee, for example. Agricultural activities have caused their populations to shrink, nearing extinction. 

Most native species are solitary. They nest alone and don’t share child-rearing responsibilities.

Native species are harder to track, unlike their cousins, the honey bee. However, their efficiency as pollinators has motivated some farmers to invest in them. Alfalfa farmers buy alkali bees to aid in the pollination of this vital crop.

Foreign Bees

The early European settlers introduced honeybees, specifically the European dark bee, in the 1600s. Since then, not only have we imported different races of honeybees. We have imported some solitary ones as well, e.g., the Japanese horned bee.

Advantages of foreign bees

One major advantage is the home-grown crop of honey we now love and enjoy. Without these species, honey production would be at its minimum, and we would have to import honey.

It has also allowed us some agricultural benefit because, despite being less efficient than the native species, their numbers make up for this deficit. That has created an industry of its own, allowing beekeepers to increase their income streams by offering pollination services.

They are also less specialized, meaning if one source of nectar is absent, they’ll find the next best thing. With wild spaces and indigenous plants at risk, honeybees’ adaptability to changing food sources gives them a better chance at survival.

Disadvantages of foreign bees

One disadvantage is the introduction of pests and diseases. These have had a devastating effect, such as in the case of varroa mites. Many beekeepers lost colonies because of this tiny arachnid.

The solution is genetic. Some bees exhibit certain hygiene traits that enable them to get the mite off them, e.g., Saskatraz bees. The colony can thrive without chemical intervention because they groom the mites off them.

Another potential problem is bee-human conflict seen especially with Africanized bees. These were accidental imports that have settled down and made this their home.

The original African bee is from the Savannah grasslands in East Africa, where it has to contend with aggressive predators. That has caused them to react explosively when under a perceived threat.

Despite their outbursts of defensive behavior, they do have some advantages. The bees fare well in the presence of mites, and their queens tend to be prolific. They grow and live in colonies at a fast rate.

In Mexico, for instance, they have learned to harness these super defenders and profit from them. Also, the people in Africa have lived with and profited from them, so they are not senselessly destructive. However, as a new beekeeper, it is important to identify aggressive behavior and requeen, if necessary.

Types of native bees

Miners

The miners dig out tunnels in patches of bare soil in your garden. Although they are solitary creatures, they can live in clusters. But there’s no division of labor. Each female is responsible for setting up the offspring for the future.

Some of these superb pollinators include squash bees that specialize in pollinating squash. Alkali bees are mining bees too. Farmers build habitats for them using a tarp and clay.

Cavity seekers

These little ladies move into existing cavities. If you have a bee hotel, these will be some of your frequent visitors. 

Leafcutters and Mason bees

Both of these lead solitary lives. They rely on no one, working and living independently.

Leafcutters, thriving prominently in North America, use their mandibles to cut pieces of the leaf off plants, such as roses. They use these leaves to line the cavity creating some kind of origami tube. They then lay an egg, place food in the form of pollen bread, and seal the chamber.

Mason bees are a type of native bee more common in the US. Smaller than a honey bee but blue-black in color, they got the name by the fact that they have the habit of building their nest and sealing it with mud.

Interestingly, masons are fond of sipping the nectars from flowers. However, only female bees bring pollen back home. Unlike other different types of bees that carry pollen on their legs, mason bees carry the pollen on the underside of their abdomens.

Bumblebees

Bumblebees, with their lovely black and yellow coloring, are great pollinators for plants that require a good shake before giving up pollen. They find abandoned burrows in the ground where they build their nests.

Bumblebees are social, like honey bees, but the colony remains relatively small. Each colony starts with one queen. She lays a few eggs and cares for them until they emerge as adults.

Then, the roles switch. They take care of her, and she starts populating the colony. The colony only exists to bring the next generation of queens. Once the queens emerge, bumblebees find a burrow and hibernate for the winter, and the cycle begins again in spring.

Carpenter bees

If you type ‘carpenter bees’ into any search engine, the first few links will direct you to pest control. Sure, carpenter bees drill holes in wood, as their name suggests, but I wouldn’t call them pests. Unlike termites, carpenter bees don’t eat the wood; they just make tunnels.

Sometimes, more than one carpenter bee will share an entrance tunnel, but they are still solitary bees, so the damage caused would be minimal.

Because of their size, carpenter bees can be intimidating, but they rarely sting.

You’ll usually see a large bee hovering outside a tunnel. That’s usually a male waiting for a female to emerge from the nests. He makes a big fuss but doesn’t have a stinger.

Africanized Honey Bees

Also known as killer bees, this type of bee originated in Brazil and a hybrid of two subspecies, the Africanized and European species. In the US, they prefer to stay in states with warmer climates. As its name suggests, killer bees attack different types of bees and people when their nests are threatened.

With yellow and black colors, it is often hard to distinguish this bee from the European honey bee or Western honey bee. When in doubt as to what species of bees you have in your garden, it is best to consult a pest control specialist before tackling its nest.

Lesser-known bees

There are bee types that delegate child-rearing duties to other bee species. They are referred to as cuckoo bees because they lay their eggs in nests, usually in a solitary bee nest, and fly away to continue life carefree. The egg will hatch, eat the stores left for the intended egg and even eat the other larva.

A testament to how varied the bee family is. Unlike other common types of bees, these don’t make for great pollinators. They have very smooth bodies because, without the need to feed the young, they have no reason to collect and carry pollen.

Final Word

Native bee species are vital for our existence. The attention that a honey bee gets is great for creating awareness for all the terrible things happening to most bees, but we can do more to help our native friends survive.

Let the lawn overgrow, grow flowering plants and native flowers and bushes to encourage some six-legged visitors. Bees such as the azalea bee could benefit from some lovely rhododendrons and azaleas in your garden.

If we all do our part, we can make a difference.
