1. Bumblebees Belong to a Genus of 265 Species
The IUCN SSC Bumblebee Specialist Group recognizes 265 species of bumblebees in the world, but the conservation status of many of them remains unknown. Some species are difficult to determine, as they don't differ much in features. In the U.S., the widely distributed eastern bumblebee is one of the most recognized thanks to its signature yellow and black stripes, but other species are known for having darker coloration and even red stripes.
2. They Do Not Produce Honey
Honeybees collect honey to survive through the winter, but bumblebees don’t need to prepare for the cold because they die in the fall. Only new queen bumblebees hibernate and make it until spring—their naturally depressed metabolism gives them a longer lifespan than the rest of the colony. While wild bumblebees do collect sugary nectar, they always consume it before they have a chance to convert it into honey.
3. They Can Detect the Nutritional Quality of Pollen
Along with nectar, bumblebees also collect the pollen made by flowers. In 2016, researchers at Penn State found that bumblebees can actually detect the nutritional quality of pollen, an ability that helps them choose the best plant species and optimize their diets. Bees can do this by sensing a chemically complex substance in pollen to determine its nutritional content.
This ability comes in handy, especially considering that pollen makes up a bumblebee’s primary source of protein and lipids (they get their carbohydrates from nectar). The study’s findings will also help identify the prime plant species that provide high-quality nutrition for bumblebees to aid in their conservation.
4. They Beat Their Wings 200 Times per Second
Bumblebee wings move faster than the human eye can detect, so scientists use high-speed cameras and computer vision techniques to analyze their wingbeats. Using a combination of virtual stereo systems and intersecting laser beams, researchers in Querétaro, Mexico, found that a bumblebee’s wings beat an impressive 200 times each second.
5. They Create a Vibrating Pulse for Pollination
The wingbeat helps create the vibrating buzz that makes bumblebees such great pollinators. Studies on pollination strategies of a critically endangered lily species found that bumblebees made up over 81% of flower visits, but they spent significantly less time on each flower than other bee species, suggesting a faster efficiency as well.
6. Bumblebees Have Five Eyes
Bees need their complex eye system to navigate and pick up colors, shapes, and UV markings on flowers. For that reason, bumblebees have five eyes, including two main ones with about 6,000 facets and three smaller ones on the top of their heads. The small eyes sit close to each other but give the bee different perspectives.
Bumblebee eyes are larger than honeybee eyes and lack the interfacetal hairs on the eye surface—scientists aren’t sure why.
7. They Have Impostors
Just like a cuckoo bird leaves its eggs in a foreign nest for another bird to raise, species of cuckoo bumblebees sneak into other colonies to lay their eggs. In many cases, cuckoo bumblebees lose their social ability to rear and produce workers over time, so they must rely on established hives to do the work for them. Unlike cuckoo birds that just have to trick one or two birds, a cuckoo bumblebee must fool an entire colony—just one of the reasons why they are so rare and, in some cases, critically endangered
