Mining bees are wild bees that live underground

Once you start studying the pollinators in your garden, you will see many different types. If you start recognizing some of your visitors, you will look forward to seeing those old friends and indentifying new ones. People seem to care more about the things they can put a name to, so I encourage you to spend some time with identifications.

The different species within the genera are very difficult to discern, but most people can learn to identify down to genus. That in itself is an accomplishment!

For instance, take the genus Andrena. The 1300 species in this genus are also called “mining bees” because they nest in the ground. Like most bee species, they are solitary, which means that all females are fertile and each one builds a nest by herself, provisions the nest with pollen and nectar, and lays the eggs. Unlike a honey bee colony, there are no workers, no honey production, nor any comb building.

The eggs hatch and the young bees progress through the larval stage to the pre-pupal stage before winter sets in. During the winter they remain in the pre-pupal stage until early spring when they complete their metamorphosis into adult bees, both male and female. The adults emerge from the ground, mate, and the females of this new generation begin to build their homes in a new underground chamber.

Solitary bees are often oligolectic, and Andrena bees are no exception. An oligolectic bee is one that collects pollen from only a select few plant species. Often these plants are very closely related—in the same family or even the same genus. In fact, some species of Andrena bees are monolectic, meaning they collect pollen from one—and only one—species of plant. It is easy to see that if that plant becomes rare or extinct, so does its pollinator. No wonder our wild bees are in trouble!

Andrena bees range from about 8-17 mm long. The females in this genus can be distinguished from other bees by the velvety patch of hair between the eyes and the antenna bases. They also have well-developed corbiculae—or pollen baskets—on the sides of the thorax and hind legs. Since the males do not collect pollen, they are not as hairy as the females. The males are also shorter and narrower than the females.

Because Andrena bees build their nests underground, they are adversely affected by farming practices such as tilling, plowing, disking, and spading. They also do not thrive in ground that has been completely cleared of vegetation because they like nesting sites that are protected from weather extremes by bushes or trees. Heavy mulch is also bad for Andrena bees because the females are not able to dig through mulch to get to the soil.

Needless to say, insecticides readily kill Andrena bees and herbicides kill the plants on which they are dependent. Maintaining a pesticide-free garden with plenty of bare soil and many plant varieties—including native species—is the best way to attract and conserve most native bees, including Andrena.

It’s really hard to say. About 4000 species of bees live in North America alone, and most live underground. A picture would help, otherwise I would be guessing.

It’s cool, though. I’m glad you noticed them and you are trying to find out what they are. If you do find out, please let me know.

Hi. My father-in-law put a plant in the ground Tuesday the 14/06/2011 and when he got up in the morning he noticed that the leaves on the plant had gone. When we sat in the garden today 16/06/2011 we saw a couple of bees going into the ground. Do you know if they eat plant? Would be nice to have some reply on this because it is weird and I have never seen them before.

Thanks a lot

Danny,

If what you saw were really bees, they would not have eaten the leaves. Bees take nectar and pollen from plants, but they don’t eat leaves. Some bees, like leafcutters, will take a small part of a leaf for their nests, but they don’t strip them bare. Even wasps and hornets don’t eat leaves.

If the leaves disappeared so quickly, I would say it was most likely slugs or snails–or even deer or rabbits–that did the damage, not bees.

This is the second year I have had a bee–huge, but docile–does not sting, but butts disapproval. I cannot pinpoint species. 1-1 1/4 inches long. Black with wing veining. Bright yellow furry “goatee” on black head. Thorax has three rows of dingy (muddy) yellow “fur” and black. The abdomen is half the size of the bee and black, hairless or sparsely so.

He is the guardian of my enclosed patio, chases other mining bees much smaller away. If I leave the gate open, he disapproves and flies in and out of it, to my sliding door and back, repeating until I shut it. If a wind is blowing, he is upset and checking each of my moving, hanging objects. I have a large batch of potted yellow-orange pansies that are fragrant, violets, and basket of Gold in front of the patio.

He brought his mate around for me to see one day–I know it was a mate, because he didn’t chase the similar-sized bee away. BEE, as I call him, will come when I call him, and he hovers a foot away from my face. If I have guests, he checks them out. I warn all, that he is doing just that and will not sting. However, when I hired a friend to clean out my car of glass from a baseball coming through, we had the gate open a long time. I sat and watched the antics. BEE was chasing much smaller mining bees away, sometimes several at a time. One knew it was not his territory and didn’t breech where the gate had been shut.

My friend came in at the end and sat talking with me. Neither of us thought to close the gate and he butted her in the back of the head–she was closest to the gate and had used it more than me. We shut the gate and that was the end of that. One windy day I didn’t get my key out fast enough for him, and he kept butting the glass door next to my head, encouraging me to move in out of the wind, I gathered. He tolerates my guests, even if eating lunch on the patio. I cannot see it (happens fast), but he may butt with the thorax and not the head. That being why his goatee is so free of soil? I live north of Columbus, OH. BEE has “pet” status. The same bee, second year!

Interesting stuff. I know that some bees are very territorial and will chase other bees away, and I know bees will butt large creatures like dogs and humans, but your bee sounds pretty darn persistent. I have no idea what it is.

We live in the mountains of WNC. My husband used a machete and weed eater on the front yard before we left for out of town. Upon our return late last night, he was stung on the back by what we at first thought was a yellow jacket.

This morning I found an open nest in the ground with layers of “combs” around the yard that he either 1) hit with his machete, or 2) was dug up by a wild animal as we have thousands of deer as well as fox, coyote and bear in the area.

Now I’m wondering what bee is at our front doorstep. If it’s yellow jackets, I’m going to have to destroy the nest as I have children and pets and that’s our main entrance to our home (I’m physcially disabled). If it’s honey/wild mining bees then I’ll have to bite the bullet and work with stairs for awhile until they find new digs. If that is the case, any suggestions on how to help them “move” along without hurting them?

Carole,

They sound like yellow jackets, or some similar wasp, to me. Yellow jackets have combs that are usually round disks that look a lot like honey combs. This is where the young are raised. Honey bees normally nest above the ground in a tree, under an eave, or in a wall. Mining bees are usually solitary—a single bee raises a small batch of young in a small ground cavity. Mining bees do not build combs. Without any pictures, my money is on yellow jackets.

We’re about to set up a new hive in our suburban backyard. Our backyard is seriously aerated by ground bees. Should we expect any interaction between the bee varieties, especially from the ground bees robbing the honey producers? Thanks!

Dave,

You are so lucky to have native bees digging up your lawn! Seriously, I’m jealous.

The ground bees won’t affect the honey bees, although the honey bees will probably have an adverse effect on the ground bees. Honey bees are hoarders, taking as much nectar and pollen as they can possible find, whereas your ground bees take just enough to moisten their pollen balls and have an occasional snack. It is a minute quantity compared to what a single honey bee will take.

Also most ground bees, other than bumble bees, forage very short distances–a couple hundred yards, whereas honey bees can forage for miles. Once the honey bees use up what’s close, they’ll go further and further in search of food. This may wipe out your ground bees because once the honey bees take everything, the small bees may not be able to find food close enough to home. It’s possible the ground bees may forage on different plants, which would be good for them and might save them. The ground bees are in no way a threat to the honey bees and will not rob the hives. Yellowjackets and other wasps, however, often rob honey bee hives.

We have had ground bees in our yards for YEARS. I have felt they were pests until recently learning of the declining bee population. I’m now, after reading this article and others, hesitant to really pursue removing them from the yard. Is there any way to provide additional food sources for them? We live on the corner of a very busy street so our yard is limited.

Also, I just want to make sure they are not producing honey of some sort that we could use. They are sure collecting a lot of pollen compared to the honey bees I’ve seen in our backyard.

Any additional insight would be very much appreciated as I am now coming to learn to live with, and appreciate, these bees.

Thanks!

Kristin,

Ground-dwelling bees, like other native bees, are an important part of our environment and responsible for a lot of pollination, as you already noticed. They collect very little nectar compared to a honey bee. Each female lays a dozen or two eggs. For each egg she collects a ball of pollen held together with nectar. The ball is about the size of a pea. She lays the egg on top of the ball and seals up the compartment she laid it in, and then goes on to the next one. That tiny bit of nectar, along with some she eats herself, is all she ever collects. The new bee doesn’t emerge until the following spring.

We have THOUSANDS of mining bees and I can’t bring myself to try to get rid of them, each year their nests spread further across our lawn, even the grassy areas. But what an experience! In the weeks they are active it sometimes looks like our lawn is moving because so many of them are hovering. My children have learned to accept them, and explain them to their friends. The bees will hover on their hands, my children run the yard with flip flops on, no one has ever been stung. The only negative…in the fall our yard is taken over by the American Oil Beetle which I understand feeds off the bee larvae and I HATE the oil beetle!

Suzann,

That is so, so cool. I am jealous. I’ve heard people say that the ground can look like water with all the movement and the sun glinting off the bees. Some have even said it makes them feel “seasick.” Most of the the mining bees are small and, although they have stingers, they are not large enough or strong enough to pierce human skin. Seeing all those little bees is something you and your kids will never forget. And they are important pollinators, so hang onto them.

Hi, I currently live in Germany and I noticed a lot of bee burrows in the yard mowing. Looking closer they seem to be mining bees which I’m happy to have because they are beneficial to our yard and garden. The problem I have right now is I’ve found what look to be some wasp (yellow jackets) and am not fond of them whatsoever. My question is will the mining bees take care of the wasp, or should I try and handle them myself? My dilemma is that I’m not 100% sure which burrows belong to who? Any suggestions? Thanks!

The mining bees you have are probably the type that live singly—each bee having it’s own burrow. Yellowjackets live in big groups. They should be fairly easy to tell apart. Mining bees won’t be able to handle yellowjackets. Most of the mining bees are a fraction of the size of yellowjackets.

My mining bees come every May to my sweet corn patch. It’s approximatley a half an acre, and this year I was late getting in, and they have taken over about half of it, the sandy portion of course. I traced one of their holes once, seemed to start vertical, then angle or curve horizontal, for about a ft or so. It seems that after a couple months they, (the adults), are no longer there? There are weeds coming that I must kill with either glyphosate, or 2,4-D. I could possibly wait till the adults are gone and the holes are covered up naturally in a month or so.

Each year I till, and sometimes plow the soil, does that mean I’m killing the young or covering them with several inches of dirt on the top of their tunnel and they won’t be able to dig out next year? Why do they come back each year to the exact same spot, or is that the young adults digging their way out, and starting all over. If the adults come from somewhere, where do they come from and where do they go when they leave? I don’t want to remove them entirely, and am willing to work with them, however I need to use my plot also? Your help would be appreciated.

Such an interesting question and good observations.

First off, the term mining bee is generally used for many different species of bee that live underground, so I can’t tell you exactly how deep they go or some of the other details because there are different possibilities.

But your observations are good. The tunnels generally go straight down and then branch off, either horizontally or at an angle. One tunnel usually has a number of branches. At the end of each branch is a chamber where the bee will lay one egg on top of a ball of pollen and nectar. You are also correct that the adults live only a few weeks, then they die. The egg will hatch into a larva, and then the larva will eat the ball of pollen and nectar, and then it will spin a cocoon. In the cocoon, the bee overwinters as a pupa. When I say overwinter, it really means the entire rest of the year.

When the adult emerges from the cocoon in the spring, she first mates and then builds the tunnels and chambers to lay her eggs. Once a chamber is ready, she collects the nectar and pollen, lays an egg on top, and then builds another chamber. She does this until she dies.

So, you see, the adults don’t go anywhere. They are hatching in your field, mating, laying eggs, and dying. Then next year the new generation emerges from the same holes their mothers built. Yes, if you plow or disk the soil, you are probably destroying many of the young. Like I said, though, different species go different depths, so I can’t say for certain how deep yours are going. The reason they nest in the same place is they like sandy soil, which you said you have.

Can you tell me where you live? Just generally, like what state or province? I might be able to tell you more based on that.

I have some sort of either a bee or a beneficial wasp in my yard. The first year I noticed a bunch if holes about the size if a pencil. One day outside I saw the insects. There was a swarm of them all flying to where the holes are and each one would land and then wiggle down the hole. I can walk along this area when they are coming in for landings and have never had them sting or actually come near me. The ones I have seen close I can’t see a noticeable stinger. I am not wanting to eradicate my yard of them if they are peaceful, but I don’t know what they are. I realize that you can’t ID these guys by my description alone, so if I can catch one to get a good photo of is there an email address I can send a photo to? Thanks for your help.

Stacey,

Most solitary bees that live in the ground seldom sting. Many of them have stingers that are too small to go through human skin. You should leave them alone and let them pollinate. They will only be active for a few weeks and then you won’t see them again for a year.

I have been obsessed with finding out how to get rid of my bee problem. We have hundreds of holes in the ground and I was worried considering I have three kids. After doing a lot of research I just found out that I have miner bees. I have a new understanding for the little creatures and I feel bad for wanting to kill them. I have a friend who is a beekeeper (in MT) so I have a secret obsession to want to do that. Now that I have a miner bee colony, I can say with some reservation that I am a beekeeper and I will visit my little guys/girls regularly. I am a nerd.

Me likey miner bees,

Certainly if you are keeping them and not killing them, you can safely call yourself a beekeeper. Thank you so much for seeing the light. The little uncelebrated bees of the world provide services to our ecosystem that we don’t fully understand, but we know enough to know they are important. There is some variation among the species, but most of the mining bees are so small their stingers can’t puncture human skin, so they aren’t much of a threat to you or your family.

You are lucky to have the bees. I’m preparing to travel a great distance just to photograph ground-dwelling bees and their homes, so I consider you blessed. If you want a challenge, try to photograph them coming and going from their burrows. If you get a good one, I’d be happy to publish it here on the site.

So congratulations! You are a beekeeper . . . and you don’t need the reservations.

I have been out cutting the grass outside in my front garden this morning and noticed a lot of what looked like honey bees emerging out of the ground! I had no idea that bees could dig into the ground until I have looked this up…I know there is a decline in bees in England so I’m really hesitant to destroy the nest! Are these bees easily annoyed at all? I have children but can direct them to stay away from where I have found this nest so could I just leave them alone?

Rusty
Reply

Shell,

I can’t give you a good answer. Basically, there are 20,000 species of bees worldwide and 70% of them live in the ground. I don’t know how many live in England, but probably a lot. Many of the ground dwellers look similar to honey bees, especially some of the Anthophora and some of the Andrena. Honey bees generally do not live in the ground, although they do occasionally. Bumble bees usually live underground as well. Many solitary ground-dwellers live in groups or communities, so even though they each have a separate nest, the nests are close together. Most solitary bees are not at all aggressive, and many have stingers that cannot penetrate human flesh even if they wanted to.

Hi,

I was weeding today while slowly walking through ankle-deep ground cover (vinca). After I pulled a weed, I suddenly felt a sharp pain on my arm and then felt “bees” zipping all around me. I started to run and it took a couple minutes to shake the bees! I was stung several times on both arms (and it killed!).

When I went back to the ground cover to figure what kind of bees they were, I saw several buzzing around the ground, some of them seemed to be slowly flying back into the area under the ground cover. I couldn’t get one to stay still for a picture with my cell phone, but they did NOT look like wasps and definitely were not yellowjackets. The best way to describe them were maybe somewhat like a honey bee?? Maybe a little darker? I googled about “ground” bees and most websites say that they are not aggressive and rarely sting. This bee was aggressive! What do you think it could be? If it’s native, I don’t want to hurt/remove them… its in an area where not many people go. Just curious… love nature!

Hi Karen,

I’m just guessing, of course, because I can’t see the bee. But if it looks a lot like a honey bee–generally the same size and shape–it could be an Anthophora or maybe an Andrena. Both types live in the ground. Anthophora are often confused with honey bees. These are large groups of bees with many species. Most are gentle most of the time, but if they get riled up they can definitely sting, especially the larger ones. The very small ones usually are not strong enough to penetrate human skin.

You probably got close to an aggregation of nests. These bees are solitary ground dwellers, but although each bee has her own nest they often live in groups or communities. The other possibility is some type of ground-dwelling wasp. Some of the less familiar wasps and bees are very difficult to distinguish in the field. Not only that, but many solitary wasps have evolved to imitate the appearance of bees. This is so they can easily invade the bee’s nest and lay their eggs there.

At any rate, I’m glad you are willing to let them live. Most of these solitary bees and wasps are active for only a few weeks a year and then you won’t see them again until the same time next year.

This morning I noticed a hole in my garden under my lavender bush. Something had been digging, there were bees flying around obviously unhappy. As I was putting the soil back the bees kept chasing me away. I know there are bees that live underground but from what I have read they don’t produce large amounts of honey. What animal would want to get at their nests? I do have skunks that frequently visit my yard, could it have been them and what were they looking for?

Rusty
Reply

Mary,

When mammals invade bee nests–and this includes big ones like bears–they are not looking for honey as much as bee larvae. The larvae (the grub stage) are extremely high in protein and are an excellent food source. It could have been a skunk, or even something smaller, that was looking for bee larvae. The larvae are plentiful this time of year, so it would not surprise me at all.

I discovered a hole the size of a basketball where some animal had unearthed a nest. On the ground were large pieces of combs that appear empty. Bees are still coming in & out of this hole from deeper in the ground. Will the bees dig out if I fill in the hole? Did the animal excavation eliminate the survival of this particular nest?

Rusty
Reply

Maureen,

To me it sounds like a wasp nest. Are the combs round like plates or some other shape? If the insects are still coming in and out, they may be able to recover from the attack. If you fill the hole too tightly, they will likely become trapped. If you fill it loosely, they can probably dig through it. If they are wasps, and if you live in a place with cold winters, the colony will die out with the first freeze.

While mowing today, I discovered a large hole in my yard, at least as big as a softball, with many., many little bees going in and out of the hole. They are not yellow jackets or sweat bees. One of the little buggers stung me through my thin top! I don’t want to destroy them, but I have to mow there or it will be a jungle! I live in Kentucky. Do you have any advice?? Can you send an email to me to help me decide what to do?

Rusty
Reply

Karen,

It sounds like a semi-social bee that is using a common entrance area. I’m guessing they have individual nests coming off separate tunnels under the ground. Or it may be a primitively eusocial type of bee. In any case, fully 70% of the 20,000 species of bee live underground, so it is difficult to say what it is. You say it’s not a sweat bee, although I am less sure of that. There are something like 500 species of sweat bee in North America. They are very different from each other and many of them have some degree of sociality, like what you describe.

These bees are important pollinators and part of a healthy ecosystem, so it makes no sense to destroy them. The nest will soon go inactive as cold weather approaches. Put on some heavier clothes and just mow over it. Or mow around that area. Sometimes conserving valuable resources causes some amount of inconvenience in our lives, but imagine where we would be without them.

In my chili pepper field (Indonesia), there are some insect like bees. It’s black, digging on soil, making its home inside, eating caterpillar that eat my chili leaf (HELP ME A LOT). It’s solitary I think, but many of them, hundred maybe thousand. Soil that it dig have some like earth worms shit, it’s also like heat of sun, because on field full of weed (shade from sun), the population is small, it’s also pollinate my chili. That bee resist Deltamethrin, Chlorpyrifos, Imidacloprid, Abamectin, and even tobacco leaves extract, because it’s population growing even when I spray my chili field against leaf mites (on recommended dosage of course), but sadly, it’s gone if raining. It’s not aggressive even when walked near them (but of course who want to touch them!), is that a real bee family or some kind of other beneficial bugs??? Help me please. Oh yeah, it is sized around 1,5 cm long.

Arya,

It’s impossible for me to say for sure, but if it looks like a bee, burrows in the soil, lives in communities, likes full sun, pollinates chilis, and eats caterpillars, my guess it that it is some type of wasp. It’s not a bee if it eats caterpillars. That you have any living thing in your field is a miracle, given your spray regimen.

Hi!
Thank you for this wonderful information. I have a question–can I put rocks down on top of where the mining bees came out this spring? Will the bees be ok? I will leave spaces between the rocks for them to get in and out, but it won’t be the stretch of dirt that was there before. (I won’t use gravel; the rocks are softball-to-basketball sized.) And once the bees have come out of their holes and stopped buzzing around, is that the time to put the rocks down? Thank you!

Rusty

Stacy,

Is that like Monmouth College in NJ?

Bees definitely like areas of bare dirt, but as long as you leave space between the stones I think they will be okay. It depends to some extent on the type of bee you have. Some nest randomly, wherever they find room. Others like to build large, extended communities where they benefit from each others ability to find off intruders.

As soon as they emerge they will mate and start to build more nests. So as they are emerging is probably the best time to add the rocks. At least you know where the old and new openings are so you won’t cover them up.

That’s Monmouth College as in Monmouth, Illinois. The same Scottish Presbyterians who founded Monmouth College (now Monmouth University) in New Jersey kept moving west and founded Monmouth College out here in the prairie, where, apparently, mining bees are very happy!

Thank you so much for your helpful response. I will get out there this coming weekend to try to reposition the rocks selectively and decoratively!

Matt,

You are so lucky to have native bees in your yard! What an asset! Please don’t kill them.

I’m sure you’ve heard that bees are in trouble all over the world and we have to do everything possible to save the ones we have left. Most solitary mining bees do not sting or sting only lightly. They are not dangerous, and they are active only a few weeks per year. It depends on the species but, most probably, at the end of a month or so, you won’t see them again until next year.

Rather than keep your kids away, show them the holes and explain that by pollinating the flowers, bees allow seeds to be formed and plants to grow, including the plants we eat. I don’t know the age of your kids, but if they are school age, they will be the most popular kids in town once their friends know they have mining bees.

Your kids face many greater risks than those posed by bees: riding in a car, crossing the road, exposure to pathogens at school, riding bicycles, even falling off a curb are all more dangerous.

Please see the bees as an opportunity: a learning experience for the kids, a chance to better the environment, and most importantly, a way that you can do your part to help the bees.

Rusty’s right. We’ve had mining bees for years. They aerate the soil and do their pollinating. We’ve walked on them, run lawn mowers over them, and never have been stung. I still feel guilty about my first silly and futile attempts to eradicate them.

Dave–True! My mining bees appear for about ten days in the spring, and then they’re gone. They do no harm and they’re a lovely harbinger of spring. My son and the neighbor boys have played around them every year—and no one has ever been stung or harmed in any way.

Matt, I hope you can find a way to co-exist. If you don’t use that part of the yard for a week or so, it should be ok, in my experience.

I am glad I came across your website. We have mining bees that have grown to cover a good percentage of our yard. We were thinking of spraying pesticide to get rid of them because we have children. We have educated them and assure them they are harmless but with a special needs child afraid of bugs she becomes frantic and has anxity attacks. Hopefully we can ease her fears because I believe they are more beneficial as neighbor’s after reading your blog.
