New Jersey’s suburban gardens and preserved forests host surprising numbers of ground-nesting bee species. When you think of bees, you probably picture honeybees in hives, but the truth is that most of the bees in your backyard live alone in tiny tunnels underground. Understanding the different types of bees in New Jersey helps you support these vital pollinators right where you live.
Bees are not just for beekeepers. They are for anyone who grows tomatoes, enjoys flowers, or cares about a healthy ecosystem. New Jersey has over 400 species of native bees, plus a few introduced ones. Each type has its own habits, favorite plants, and nesting style.
This guide covers the main groups you will encounter in the Garden State. You will learn to identify them, understand their life cycles, and make your yard more bee-friendly. Let’s start with the most famous one.
Honey Bees In New Jersey
Honey bees are not native to North America. They arrived with European settlers in the 1600s. Today, they are the most recognized bee in New Jersey, thanks to their role in agriculture and honey production.
These bees live in large colonies with a single queen, thousands of workers, and a few hundred drones. They are social insects that communicate through dances and pheromones. You will see them on almost any flower, from dandelions to apple blossoms.
Honey bees are generalists. They visit many plant species, which makes them excellent pollinators for farms. New Jersey’s blueberry, cranberry, and peach crops depend heavily on managed honey bee hives brought in during bloom time.
If you see a bee with a fuzzy, golden-brown body and a striped abdomen, it is likely a honey bee. They are medium-sized, about half an inch long. Their colonies can survive winter by clustering together and eating stored honey.
Honey bees are not aggressive unless you disturb their hive. They sting once and die. If you find a swarm, call a local beekeeper rather than an exterminator.
Bumble Bees
Bumble bees are the gentle giants of New Jersey’s bee world. They are large, round, and covered in dense hair. Their black and yellow stripes are easy to spot, and they have a slow, buzzy flight pattern.
Unlike honey bees, bumble bees are native. They live in small colonies, usually in abandoned rodent burrows or under piles of grass. A bumble bee colony has a queen, workers, and males, but the colony dies each fall. Only the new queens survive winter by hibernating underground.
Bumble bees are excellent pollinators because they can buzz pollinate. They grab onto a flower and vibrate their flight muscles, shaking loose pollen from tight blossoms. This is essential for tomatoes, peppers, and blueberries. Honey bees cannot do this.
In New Jersey, you will find several bumble bee species. The common eastern bumble bee is everywhere. The rusty patched bumble bee is endangered and rare, but it has been spotted in northern counties. If you see a bumble bee with a reddish patch on its abdomen, report it to the state wildlife agency.
Bumble bees are docile. They can sting multiple times but rarely do unless you step on them or grab them. They are early risers, coming out in early spring to start new colonies.
Carpenter Bees
Carpenter bees look like bumble bees at first glance. They are large and black with yellow hair on their thorax. But there is one big difference: carpenter bees have a shiny, hairless abdomen. Bumble bees have a fuzzy abdomen.
These bees are solitary. They do not live in colonies. Instead, a female chews a perfect round hole into wood, then tunnels along the grain to create a nest. She lays eggs inside and provisions each chamber with pollen and nectar.
Carpenter bees prefer unpainted, weathered wood like decks, fences, and eaves. They do not eat the wood; they just excavate it. The sawdust piles below the hole are a telltale sign.
Males are territorial but harmless. They hover near the nest entrance and buzz at you, but they have no stinger. Females can sting but rarely do unless provoked. The real damage is cosmetic, though repeated tunneling over years can weaken structures.
To deter carpenter bees, paint or varnish exposed wood. You can also plug old holes with wood putty or a wooden dowel after sealing them. Do not use insecticides; they kill beneficial insects and do not solve the problem long-term.
Despite their reputation, carpenter bees are good pollinators. They visit open-faced flowers like sunflowers and daisies. They are active from spring through summer.
Mason Bees
Mason bees are small, metallic blue or green bees that look nothing like honey bees. They are about the size of a grain of rice. Their name comes from their habit of using mud to build nest walls inside cavities.
These bees are solitary and extremely efficient pollinators. A single mason bee can pollinate as many flowers as 100 honey bees. They work in cool, wet weather when honey bees stay inside.
Mason bees nest in pre-existing holes like hollow stems, beetle tunnels, or holes drilled in wood blocks. They do not dig their own tunnels. The female collects mud, carries it to the nest, and builds a series of cells. Each cell gets one egg and a ball of pollen.
In New Jersey, the most common mason bee is the blue orchard bee. It emerges in early spring, just as fruit trees bloom. If you have apple, cherry, or pear trees, mason bees are your best friends.
You can attract mason bees by putting up a bee house with paper tubes or drilled blocks. Place it in a sunny, sheltered spot facing south or east. Make sure the tubes are clean and replaced yearly to prevent mites and diseases.
Mason bees are gentle. Males have no stinger, and females only sting if crushed. They are a joy to watch as they zip from flower to flower with mud on their legs.
Leafcutter Bees
Leafcutter bees are medium-sized, dark bees with pale bands on their abdomen. They get their name from the neat, circular pieces they cut from leaves. You might see half-moon shapes on your rose bushes or lilacs.
These bees are solitary and nest in cavities. They use the leaf pieces to line their nest cells, wrapping each egg in a cozy green blanket. They prefer soft, pliable leaves like rose, lilac, and redbud.
Leafcutter bees are important pollinators for alfalfa, carrots, and onions. They are also common in gardens. They are active in mid-to-late summer, later than mason bees.
They are not aggressive. The females can sting but rarely do. The leaf damage they cause is mostly cosmetic and does not harm the plant. If you see cut leaves, leave the bees alone. They are doing you a favor.
To support leafcutter bees, provide nesting materials like hollow stems or drilled wood blocks. Plant a variety of flowers that bloom in summer, such as coneflowers, zinnias, and bee balm.
Sweat Bees
Sweat bees are small, often metallic green or bronze bees. They get their name because they are attracted to human sweat, which they drink for salt. They are harmless but can be annoying on hot days.
These bees are mostly solitary, though some species nest in loose groups. They dig shallow tunnels in bare, sandy soil. You might see tiny mounds of dirt with a hole in the center in your garden paths or lawn edges.
Sweat bees are generalists and visit many flowers. They are important pollinators for wildflowers and crops. They are active from spring through fall, with different species peaking at different times.
There are dozens of sweat bee species in New Jersey. The most common are the green metallic sweat bees, which are bright emerald or coppery. They are about a quarter-inch long and very fast.
If a sweat bee lands on you, do not swat it. Just blow gently or brush it off. They rarely sting, and if they do, it is mild. They are beneficial insects that help your garden thrive.
To attract sweat bees, leave some bare, undisturbed soil in a sunny spot. Avoid using mulch or ground cover everywhere. They need open ground to nest.
Mining Bees
Mining bees, also called andrenid bees, are among the first bees to appear in spring. They are medium-sized, fuzzy, and often reddish or dark brown. They dig tunnels in the ground, sometimes in large aggregations.
These bees are solitary but nest close together. You might see dozens of small holes in a patch of bare dirt, each belonging to a different female. They are not social; they just share the same real estate.
Mining bees are important early pollinators. They visit willow, maple, and fruit blossoms before other bees are active. They are generalists but prefer certain spring flowers.
In New Jersey, the most common mining bee is the spring beauty bee, which specializes in spring beauty flowers. Others visit dandelions, clover, and wild mustard.
Mining bees are very docile. They rarely sting and are easy to observe. If you see a patch of ground with many small holes in early spring, you have a mining bee aggregation. Do not disturb it; they will be gone in a few weeks.
To support mining bees, plant early-blooming native flowers. Avoid tilling or disturbing bare soil patches in early spring. They need that ground for nesting.
Long-Horned Bees
Long-horned bees are named for the long antennae on the males. They are medium to large bees, often with striped abdomens. The males have antennae longer than their bodies, which they use to sense females.
These bees are solitary and nest in the ground. They dig tunnels in sandy or loamy soil. They are active in summer and prefer sunflowers, asters, and other composite flowers.
Long-horned bees are fast fliers and can be hard to photograph. They are important pollinators for many native plants. In New Jersey, the most common species is the sunflower bee, which specializes in sunflowers.
They are not aggressive. Males cannot sting, and females are reluctant to sting. They are a sign of a healthy, diverse garden.
To attract long-horned bees, plant native sunflowers, black-eyed Susans, and coneflowers. Provide bare, sandy soil for nesting. Avoid pesticides, which kill these beneficial insects.
Plasterer Bees
Plasterer bees, or colletid bees, are small to medium bees with a distinctive face shape. They have a short, broad head and a tongue that ends in a notch. They get their name from the way they line their nests with a cellophane-like secretion.
These bees nest in the ground or in hollow stems. The female secretes a clear, waterproof material that she spreads inside the nest cavity. This lining protects the eggs and pollen from moisture.
Plasterer bees are early to mid-spring bees. They visit willow, maple, and fruit trees. They are generalists but prefer flowers with open faces.
In New Jersey, the most common plasterer bee is the yellow-faced bee. It is small, black with yellow markings on the face. It is easy to overlook but common in gardens.
Plasterer bees are gentle and rarely sting. They are important for early-season pollination. To support them, plant early-blooming native shrubs and trees.

How To Identify Bees In Your Yard
Identifying bees takes practice. Here are some tips to tell them apart.
- Look at size. Honey bees are medium. Bumble bees are large. Sweat bees are tiny.
- Check the abdomen. Shiny and hairless? That is a carpenter bee. Fuzzy? Bumble bee or honey bee.
- Watch the flight. Slow and buzzy? Bumble bee. Fast and darting? Sweat bee or long-horned bee.
- Look at the face. Yellow markings? Plasterer bee. Long antennae? Male long-horned bee.
- Notice the nest. Hole in wood? Carpenter bee. Hole in ground? Mining bee or sweat bee. Cavity with mud? Mason bee.
Use a field guide or app for help. Take clear photos from above and the side. Note the date and flower type.
Why Native Bees Matter More Than Honey Bees
Honey bees get all the attention, but native bees are often better pollinators. They are adapted to local plants and weather. They work in cool, wet conditions when honey bees stay home.
Native bees also do not suffer from colony collapse disorder. They do not need human management. They are self-sufficient if you provide habitat.
Many crops, like tomatoes and blueberries, are more efficiently pollinated by native bees. A study in New Jersey found that wild bees alone provided enough pollination for some farms.
Supporting native bees is simple. Plant native flowers, avoid pesticides, and leave bare soil for nesting. You do not need a hive to be a bee hero.
Common Mistakes People Make
Many people accidentally harm bees. Here are mistakes to avoid.
- Using pesticides on flowers. Even organic ones can kill bees.
- Removing dead wood or stems. These are nesting sites.
- Mulching every inch of soil. Ground-nesting bees need bare dirt.
- Mowing too early. Spring bees need dandelions and clover.
- Killing carpenter bees without understanding them. They are pollinators too.
Small changes make a big difference. Leave a patch of your yard wild. Plant a bee garden. You will see more bees and healthier plants.
Frequently Asked Questions
What is the most common bee in New Jersey?
The most common bee is the honey bee, but it is not native. Among native bees, the common eastern bumble bee and various sweat bees are very widespread.
Are there killer bees in New Jersey?
No. Africanized honey bees, or “killer bees,” are not established in New Jersey. They are found in warmer states like Texas and California. The bees you see are safe.
How can I tell a bee from a wasp?
Bees are fuzzy and have flat, wide back legs for carrying pollen. Wasps are smooth, narrow-waisted, and often more aggressive. Bees are vegetarians; wasps eat other insects.
What should I do if I find a bee nest in my yard?
Leave it alone if it is not in a high-traffic area. Most bees are harmless and will not bother you. If it is a ground nest, mark it and avoid stepping there. If it is a honey bee swarm, call a beekeeper.
Do all bees sting?
Only female bees have stingers. Males cannot sting. Most bees are not aggressive and sting only in self-defense. Solitary bees rarely sting at all.
Understanding the types of bees in New Jersey helps you appreciate the diversity buzzing around you. Each species has a role. By making small changes in your garden, you can support them all. Start by planting a few native flowers and leaving some bare soil. The bees will thank you with better pollination and a healthier yard.
