Hawaii’s isolation led to unique bee species found nowhere else on Earth. When you think about the **common bees in Hawaii**, you might picture the familiar honeybee, but the islands are home to a fascinating mix of native and introduced species. Understanding these bees helps you appreciate the delicate balance of Hawaii’s ecosystems.
Most people don’t realize that Hawaii has over 60 species of native bees, all descended from just one or two ancestral species that arrived millions of years ago. These native bees are mostly solitary and don’t produce honey. They are crucial for pollinating native plants like the silversword and ohia lehua.
In addition to natives, several introduced bee species have made Hawaii their home. These include the European honeybee and the large carpenter bee. Each species plays a different role in the environment, from agriculture to backyard gardens.
Let’s look at the most common bees you’ll encounter across the islands. This guide will help you identify them and understand their behavior.
Common Bees In Hawaii
Yellow-Faced Bees (Nalo Meli Maoli)
These are Hawaii’s only native bees in the genus Hylaeus. They are small, black, and have yellow or white markings on their faces. Unlike honeybees, they are solitary and do not have a queen or workers.
You can find them on all major islands, especially in coastal areas and dry forests. They nest in hollow twigs, stems, or holes in wood. They are excellent pollinators of native shrubs and trees.
Sadly, seven species of yellow-faced bees are now listed as endangered. Habitat loss and invasive species are the main threats. If you see one, consider yourself lucky.
- Size: Very small, about 4-7 mm
- Color: Black with yellow/white face marks
- Behavior: Solitary, non-aggressive
- Nesting: In pre-existing cavities
European Honeybee (Apis Mellifera)
This is the most recognizable bee in Hawaii. Introduced by humans for honey production and crop pollination, they are now widespread. You’ll see them in gardens, farms, and wild areas.
Honeybees live in large colonies with a queen, workers, and drones. They produce honey and beeswax. They are generalist pollinators, visiting many different flowers.
In Hawaii, honeybees are vital for agriculture, especially for macadamia nuts, coffee, and tropical fruits. However, they can compete with native bees for food and nesting sites.
- Look for fuzzy, golden-brown bodies with black stripes.
- They are medium-sized, about 12-15 mm.
- They are social and live in hives.
- They sting only when threatened.
Large Carpenter Bee (Xylocopa Sonorina)
This is the biggest bee you’ll see in Hawaii. Females are solid black, while males are tan with greenish eyes. They are often mistaken for bumblebees, but bumblebees are not native to Hawaii.
Carpenter bees get their name from their nesting habit. They chew perfectly round holes into wood, such as fence posts, decks, or dead tree branches. They are solitary but may nest near each other.
They are powerful pollinators, especially for large flowers like passionfruit and morning glories. They are not aggressive, but females can sting if handled roughly.
- Size: Large, about 20-25 mm
- Color: Female black, male tan
- Behavior: Solitary, loud buzzing
- Nesting: In wood tunnels
Small Carpenter Bee (Ceratina Spp.)
These are much smaller than the large carpenter bee. They are dark, metallic blue or greenish in color. They are also solitary and nest in soft pithy stems, like those of sunflowers or blackberry bushes.
You can find them in gardens and disturbed areas. They are important pollinators for many small flowers. They are very docile and rarely sting.
They look similar to some sweat bees, but their nesting behavior is different. Look for them buzzing around stems and small blossoms.
- Size: Small, about 6-10 mm
- Color: Metallic blue or green
- Behavior: Solitary, gentle
- Nesting: In pithy stems
Sweat Bees (Lasioglossum Spp.)
These are small, often metallic bees that are attracted to human sweat for salt. They are common in Hawaii, especially in sunny areas. They can be green, blue, or bronze in color.
Most sweat bees are solitary, but some are semi-social. They nest in the ground, digging small tunnels. They are important pollinators for many native and introduced plants.
They are not aggressive, but they may land on your skin to lick sweat. If you swat at them, they might sting, but the sting is mild.
- Size: Small, about 4-8 mm
- Color: Metallic green, blue, or bronze
- Behavior: Solitary or semi-social
- Nesting: In ground burrows
Leafcutter Bee (Megachile Spp.)
These are medium-sized bees that cut neat circles from leaves to line their nests. You may notice perfect round holes in your rose or bougainvillea leaves. They are solitary and nest in cavities.
Leafcutter bees are excellent pollinators, especially for alfalfa and other crops. They carry pollen on their underside, not on their legs. They are gentle and rarely sting.
They are often mistaken for honeybees but are slightly darker and have a broader abdomen. Look for them carrying leaf pieces to their nest.
- Size: Medium, about 8-14 mm
- Color: Dark with pale hair bands
- Behavior: Solitary, nest in cavities
- Sign: Circular cuts on leaves
Mason Bee (Osmia Spp.)
Mason bees are not as common in Hawaii as on the mainland, but they are present. They are solitary and use mud to build nest partitions. They are usually metallic blue or green.
They nest in pre-existing holes, like beetle burrows or hollow stems. They are very efficient pollinators for fruit trees. They are docile and sting only if trapped.
You can attract them by providing nesting blocks with holes. They are early season pollinators, active when temperatures are cooler.
- Size: Medium, about 8-12 mm
- Color: Metallic blue or green
- Behavior: Solitary, uses mud
- Nesting: In cavities
How To Identify Common Bees In Hawaii
Identifying bees can be tricky. Here is a simple step-by-step guide to help you tell them apart.
Step 1: Look At Size
Is the bee tiny (under 10 mm), medium (10-15 mm), or large (over 15 mm)? Large carpenter bees are the biggest. Yellow-faced bees are the smallest.
Step 2: Check Color
Is it fuzzy and golden? That’s a honeybee. Is it solid black? That’s a female carpenter bee. Is it metallic? That’s a sweat bee or mason bee.
Step 3: Observe Behavior
Does it fly in a straight line or hover? Honeybees fly directly. Carpenter bees hover and dart. Does it land on you? That’s likely a sweat bee.
Step 4: Look At Nesting
If you see a perfect round hole in wood, it’s a carpenter bee. If you see circular cuts on leaves, it’s a leafcutter bee. If you see a ground hole, it’s a sweat bee.
Step 5: Note The Flower
Some bees prefer specific flowers. Yellow-faced bees like native shrubs. Carpenter bees visit large, open flowers. Honeybees visit many different flowers.
Why Native Bees Matter In Hawaii
Native bees are essential for Hawaii’s unique ecosystems. They have co-evolved with native plants for millions of years. Many native plants cannot reproduce without them.
For example, the silversword plant relies on yellow-faced bees for pollination. Without these bees, the silversword would go extinct. The same is true for many rare Hawaiian plants.
Native bees are also more efficient pollinators than honeybees for certain plants. They often carry pollen on their bodies, not just their legs, which increases pollination success.
Unfortunately, native bees face many threats. Invasive ants, wasps, and diseases harm them. Habitat loss from development and agriculture is also a problem. Climate change may further reduce their range.
How To Attract And Protect Bees In Hawaii
You can help bees in your own backyard. Here are some practical steps.
Plant Native Flowers
Native bees prefer native plants. Plant ohia, naupaka, pÅhinahina, and ilima. These provide the right nectar and pollen. Avoid invasive plants that crowd out natives.
Provide Nesting Sites
Leave dead wood and hollow stems in your garden. You can also build a bee hotel with drilled blocks of wood. Ground-nesting bees need bare, undisturbed soil.
- Leave some areas of your garden untidy.
- Do not use pesticides, especially during flowering.
- Provide a shallow water source with stones.
- Plant flowers that bloom at different times of year.
Avoid Harmful Practices
Do not use chemical pesticides or herbicides. These kill bees directly or contaminate their food. Use organic methods instead. Also, avoid weed whacking near ground nests.
If you find a bee nest, leave it alone. Most native bees are not aggressive. If you need to remove a honeybee hive, call a local beekeeper, not an exterminator.
Common Misconceptions About Bees In Hawaii
Many people think all bees are honeybees. This is not true. Hawaii has many native bees that do not make honey. They are just as important.
Another myth is that all bees sting. Male bees cannot sting at all. Female bees sting only when threatened. Most native bees are very gentle.
Some people think bumblebees live in Hawaii. They do not. The large carpenter bee is often mistaken for a bumblebee. Bumblebees are not native to the islands.
Finally, many believe that honeybees are the best pollinators. While they are good, native bees are often better for native plants. They are more specialized and efficient.
