Black and yellow stripes on bees indicate one of two things to potential predators. Either it’s equipped with a toxic bite or sting or it tastes particularly unpleasant when consumed.
Some small flies and wasps will copy the black and yellow stripes on their bellies to make potential threats think they are dangerous.
As an amateur beekeeper and gardening enthusiast, I often find myself fascinated by the different types of bees that visit my flower beds and vegetable garden. One variety I frequently notice buzzing around are bees with bright yellow and deep black stripes. Their colorful patterns make them easy to spot among the flowers. Over time, I’ve learned how to identify some of the most common yellow and black striped bee species. In this article, I’ll share tips on recognizing these striking pollinators.
Why Bees Have Yellow and Black Stripes
The bold black and yellow bands are a key identifying feature for many bee species But why do bees have this color pattern in the first place? The stripes actually serve an important purpose.
For bees, the contrasting colors help them be easily spotted by other bees. This aids with communication and finding the way back to the hive. The patterns also warn potential predators that the bee can sting, acting as a defense mechanism. Additionally, the dark and light stripes help bees absorb and maintain heat while flying.
Things to Look for When Identifying Bees
When trying to identify a specific type of bee, there are some key characteristics to pay attention to beyond just the yellow and black stripes. These include
-
Size – Some bees are tiny, while others can be over an inch long.
-
Amount of hair – Bees have varying amounts of dense hair on their bodies. Some are very fuzzy, others less so.
-
Abdomen shape – The abdomen section can be short or elongated, wide or slim.
-
Nesting habits – Identifying where a bee species typically nests can aid identification.
-
Flight patterns – The way a bee hovers and darts from flower to flower can offer clues to its species.
-
Stinger – Only female bees have a stinger. Males don’t.
-
Pollen baskets – The corbicula, or pollen basket, on hind legs are clues to bees that transport pollen back to the hive.
Combining these visible characteristics with location, season, and bloom period for flowers can help accurately identify different yellow and black striped bees.
Common Yellow and Black Striped Bee Species
Here are some of the most frequently encountered black and yellow bees you’re likely to find buzzing around your garden:
Honey Bee
The Western honey bee (Apis mellifera) is probably the most familiar yellow and black striped bee. These social bees live in large hives and produce honey. They have fuzzy yellow and brown or black bands around their abdomen. A honey bee’s stinger is barbed, so when it stings, it tears away part of its lower abdomen and dies shortly after.
Bumble Bee
Bumble bees are robust, fuzzy bees with black abdomens and yellow bands. They create small nests rather than large hives. Bumble bees are important pollinators for flowers and crops. Their stinger is smooth rather than barbed, so they can sting repeatedly.
Yellowjacket
While not a true bee, yellowjackets are common yellow and black striped insects often mistaken for bees. They are actually a type of wasp. Yellowjackets have less hair, are more slender, and are extremely aggressive, stinging repeatedly when disturbed. They usually build papery nests in trees or holes.
Cellophane Bee
Cellophane bees are medium-sized black bees with transparent wings and pale yellow stripes across their abdomen. They create nests by burying tunnel networks in bare ground. While they can sting, cellophane bees tend to be docile pollinators.
Wool-Carder Bee
One of the largest bees, wool-carder bees are up to 2 cm long and have yellow bands across their dark brown or black abdomen. The females have specialized hairs on their abdomen they use to collect plant fibers to line their nests. The males are very territorial and aggressive.
Leafcutter Bee
Leafcutter bees slice circles from leaves to build their nests. They are black with pale yellow stripes and light-colored hairy undersides designed to carry pollen. These important crop pollinators nest in existing holes and crevices. Their stingers are not very strong.
Attracting Beneficial Yellow and Black Striped Bees
Many types of striped bees are extremely valuable for pollinating backyard gardens, orchards, and wild plants. Here are some tips for attracting beneficial bees:
-
Plant a variety of early and late blooming flowers to provide bees with a constant food source. Prioritize old-fashioned varieties and native wildflowers.
-
Include specific bee-friendly plants like lavender, asters, cosmos, crocus, sunflowers, and butterfly bushes.
-
Allow flowering herbs like mint, thyme, basil, and rosemary to bloom to attract pollinators.
-
Provide fresh water for bees with a bird bath, fountain, or bee bath with floating stones for perching.
-
Install bee houses to encourage nesting. Drill holes in untreated wood or bundle reeds or bamboo tubes.
-
Avoid using pesticides which can poison bees and other beneficial insects.
why do bees have stripes?
A black bee with yellow stripes is a natural evolution. Bees know that their sting is their last line of defense and that their stripes are a much better way to keep bee predators away.
They will quickly learn the hard way that a black and yellow striped bee usually means that a meal is not worth the trouble or pain
This simple evolutionary trait has made it safer for honey bees to gather things like nectar and pollen.
Do all bees have Yellow & Black stripes?
No, not all bees display black and yellow stripes on their abdomen. Even within honey bee colonies, you will find a considerable variety of coloured bees.
This is primarily due to the drones that the Queen bee chooses to mate with. When the queen comes back from her mating flight, her brood will have traits of the drones she mated with.
This means that if one of the drones she made was darker, the young bees will have that trait when they hatch and start to grow up.
Queen honey bees normally mate with 15 to 20 drones during a mating flight.
This is also beneficial for the continued health of the hive or nest. By mating with many different bees, the Queen makes sure that her genes are spread out and lowers the risks that come from breeding with the same bees.
Other yellow and black bee species with stripes include:
- Bumblebees (Bombus spp. Known for having fuzzy fur and black and yellow stripes Various species within the Bombus genus exhibit this colouration.
- Carpenter Bees (Xylocopa spp. Have a shiny black abdomen with yellow or white spots most of the time.
- Sweat Bees (Halictidae family): Some species, like bees from the genus Agapostemon, have black and yellow stripes on their bellies.
- Mining Bees (Andrenidae family): Mining bees, such as Andrena spp. , can exhibit black and yellow abdominal stripes.
- Mason Bees (Osmia spp. Some types of mason bees, like the blue orchard bee Osmia lignaria, can have black and yellow spots.
