Black Bees? How to Differentiate a Bumble Bee vs Carpenter Bee

About Carpenter Bees

Carpenter bees and bumble bees are often confused for one another. Both are approximately the same size and can be found in some of the same places, including your garden. If you see large black bees in your yard, there are some easy tell-tale signs for distinguishing between the two.  

Bumble bees are important pollinators and are one of the few bee species who can pollinate. Specifically, they are excellent buzz pollinators, which is the process of dislodging pollen from the flower by the vibrations of their flight muscles. Currently, the pollinator population is declining, therefore, it is crucial we protect the species.

On the other hand, carpenter bees are not strong pollinators. They are known for robbing pollen from plants by creating a hole near the base of the flower to easily access the nectar. This avoids the transferring of pollen all together. In addition, carpenter bees can cause damage to your home if they nest in the wood. Carpenter bees could be the problem if you're seeing big black bees near your home.

Appearances:

A quick and simple way to tell the difference between a carpenter bee and bumble bee is to compare the appearance.

Bumble bees have soft/fuzzy hair covering their entire body called pile. It is patterned with the iconic contrasting colors of black and yellow; this type of pattern is also known as aposematic coloration. Bumble bees tend to be more plump and have a stouter-body. A bumble bee has a proboscis, which is a long tongue-like feature,  which is for gathering nectar and pollen.

The carpenter bee is not as soft/fuzzy as the bumble as it has only a small portion of hair on its middle abdomen. As for color, some carpenter bee species are all black while some have similar yellow markings to the bumble bee but only on their head. The lower abdomen has little to no hair and appears black and shiny which is why they are occasionally referred to as black bees. A female carpenter bee has mandibles on the front of her head for the purpose of drilling holes into wood.

By no means do we want to make you more confused, but let’s briefly review the appearance of a honey bee to prevent any confusion. First off, honey bees are more commonly mistaken for bumble bees due to their color similarities. However, honey bees tend to have more stripes and a few gray/white stripes on the abdomen compared to a bumble bee. Additionally, honey bees have short tongues and therefore mainly pollinate open flowers.

Behavior:

Both of these bees have extremely different behavior.

The bumble bee is a social bee and lives in an underground colony which can hold as few as 50 bumble bees; the colony is not large like a honey bee colony. Living underground allows them to avoid overheating and direct sunlight; nests in temperate regions will only last one season. The queen bee feeds constantly to gain fat, which allows her to go into a resting state and hibernate all winter. Once spring rolls around, she will emerge and create a new colony. The female bumble bee, known as a working bee, spends its days gathering nectar and working on the colony. The male bumble bee, known as a drone, also works in the colony.

The carpenter bee is a solitary bee and does not live in a colony. The female carpenter bee will find a male carpenter bee to mate and nest with. The female spends her day building the nest for the family. She has mandibles on the front of her head that vibrate quickly against the wood grains, allowing her to build impressive nests in a short amount of time. The male carpenter bees’ days are spent protecting the female and the nest. Once the nest is built, the female will lay the eggs, each in a separate chamber and pack them full of nectar. When the task is done, the female and male will die in the nest. The next spring the young carpenter bees will emerge and eat the nectar left by the female.

If you are still confused as to which type of bee is buzzing around you, try to see if you can follow it to its home. A black carpenter bee will most likely nest within the wood of your home while a bumble bee will go underground. If the suspicious bee does in fact go into a wood portion of your home,  our Best Bee Trap will help you safely and easily remove the carpenter bees and prevent damage to the wood.
