hile the decline of European honeybees in the United States and beyond has been

well publicized in recent years, the more than 4,000 species of native bees in North

America and Hawaii have been much less documented. Although these native bees

are not as well known as honeybees, they play a vital role in functioning ecosystems and also

provide more than $3 billion dollars in fruit-pollination services each year just in the United

States.

For this first-of-its-kind analysis, the Center for Biological Diversity conducted a systematic

review of the status of all 4,337 North American and Hawaiian native bees. Our key findings:

Among native bee species with sufficient data to assess (1,437), more than half (749) are

declining.

Nearly 1 in 4 (347 native bee species) is imperiled and at increasing risk of extinction.

For many of the bee species lacking sufficient population data, it’s likely they are also

declining or at risk of extinction. Additional research is urgently needed to protect them.

A primary driver of these declines is agricultural intensification, which includes habitat

destruction and pesticide use. Other major threats are climate change and urbanization.

These troubling findings come as a growing body of research has revealed that more than 40

percent of insect pollinators globally are highly threatened, including many of the native bees

critical to unprompted crop and wildflower pollination across the United States.

For this report we assembled a list of all valid native bee species and their current conservation

status as established by state, federal or independent researchers. We then conducted a

comprehensive review of all literature on those species as well as records documenting their

occurrence. From that research we identified those bees with sufficient data to assess their status,

including current and historical range, behavioral observations and studies, arriving at the first

comprehensive analysis of the status of North American and Hawaiian native bees.

We also highlight five native solitary bees species that are seriously imperiled. These

remarkable, underappreciated pollinators offer a snapshot of the threats driving the alarming

declines in many native bee species — declines that must be reversed to save these irreplaceable

native bees and the health of the ecosystems that depend on them.

Bees are in serious trouble. Native bees

indispensable to the health of the natural

world are declining globally due to

accelerating threats from agricultural

expansion, habitat loss and climate change.

[1][2] They are perilously underprotected.

Bees are the world’s primary pollinators.

With more than 20,000 species globally,

they are an essential component of

functioning ecosystems. [1][3] Without their

pollination services, many wild plants and

cultivated crops would be unable to thrive.

[1][4][5] But bees are declining across the

planet, [2][6][7][8] with more than 40

percent of insect pollinators — primarily

native bees — highly threatened. [8]

For this report we undertook the first

comprehensive review of the status of all

4,337 native bee species in North America

and Hawaii. The report showcases the

results of our overview and highlights five

extraordinary native bees that are in need of

immediate help to survive. Our analysis

concludes that more than 50 percent of

native bee species for which sufficient data

is available are declining, while 24 percent

are in serious peril.

The honeybees (Apis mellifera) most

Americans associate as essential for food

production are actually an introduced

species from Europe. [9] The majority of

native bees in North America are solitary,

ground-nesting species that collect

everything from pollen, nectar, leaves, petals

and floral oils to be used as adult food

sources, larval provisions or nest linings.

Almost 90 percent of wild plants are

dependent on insect pollination, making

bees indispensable pollinators in most

ecosystems. [1][8] Pollination services

provided by bees contribute to seed sets and

plant diversity, [1][2] as well as crop

pollination that provides 35 percent of the

global food supply or one of every three

bites of food. [8] Native bees contribute to a

significant portion to annual crop value, [10]

are critically important to their ecosystems

and can be more effective pollinators than

honeybees. [11] Native bees have

profoundly shaped the world around us; they

are a keystone to many habitats and have

inspired our culture, from children’s rhymes

about bumblebees to the poetry of Emily

Dickinson. Without these tiny, tireless

creatures our world would be a less colorful

and interesting place.

Bees are declining globally, [6][7][8]

including in North America. The most

comprehensive global report thus far on the

status of pollinators found that more than 40

percent of them, mostly bees, are facing

extinction. [2] Europe is now tracking these

declines, finding that 9.2 percent of

European native bees are threatened with

extinction and 37 percent are declining.

[8][12] Their assessment likely greatly

underestimates the magnitude of the threats

because more than half the bee species

native to Europe are too data-deficient for

scientists to evaluate their status. [12]

Prior to our analysis, a similar

comprehensive overview had never been

conducted for North American and

Hawaiian bees. Status review provides

critical new information that should spur

more extensive study and protection of

North American and Hawaiian native bees.

a. Methodology

Past attempts to understand the status of

North American native bees provided the

foundation for our review, including the

Xerces’ Society Red List of Bees;

NatureServe Explorer’s list of bees and their

conservation status; and the IUCN’s

Bumblebee Specialist Group report.

However, these works focus only on small

snapshots of current trends in North

America’s bees. The Xerces Society Red

List names only 57 bees of conservation

concern, [13] while NatureServe Explorer

provides a conservation rating (Figure 1) for

287 North American native bees [14]. The

IUCN’s Bumblebee Specialist Group, which

looked at all species of North American

bumblebees, determined that 28 percent, or

13, of all North American bumblebee

species, are threatened or endangered. [15]

The limitations of past studies make clear

that there is an urgent need for scientists to

devote research efforts to native bees. Some

of the information used to determine

conservation status in these lists has not

been updated in a decade or longer. Given

the rapid rate of habitat destruction, massive

increases in pesticide use and broad

disruptions caused by climate change, the

current status of these bee species could

very likely be direr than presented.

For this analysis, we reviewed all bees

native to North America and Hawaii, a

figure often given as more than 4,000, which

we found to be 4,337 described and valid

native bee species as of January 2016. They

are valid species based on Intergraded

Taxonomic Information System (itis.gov)

through the World Bee Checklist Project

(2008-2009).

For our analysis we used the best existing

available data. We found that only 7.28

percent of North American and Hawaiian

native bees had a global conservations status

(refer to Figure 2). This number includes the

seven yellow-faced Hawaiian bees protected

under the Endangered Species Act, bees

listed by the Committee on the Status of

Endangered Wildlife in Canada, or

COSEWIC; on the Xerces Red List and on

federal or state lists of species of concern.

Figure 2: North American and Hawaiian native bees that hold a global conservation status.

Based on these existing databases and lists,

more than half of all the native bees holding

a conservation status (58 percent, or 184) are

in trouble (Figure 2). That number

encapsulates species that are: possibly

extinct; critically imperiled; imperiled; and

vulnerable (GX to G3), and is a finding that

illustrates the dire status of these insects.

To better understand the status of native

bees, we expanded further on existing

scientific information to identify additional

bees in decline. Through a literature and

occurrence record review, we began by

identifying native bees without conservation

ranking that had, at a minimum, current and

historical range available and behavioral

records from floral and nesting studies or

observations. We excluded from the

assessment species that have only been

described, with no additional information, or

collected a handful of times, to ensure those

bees would not skew the study results

toward a larger declining population. This

process of narrowing the assessment to

counter data gaps follows the methodology

of the European Red List for bees.

Our analysis yielded abundant results that

greatly contribute to existing knowledge of

native bees. We were able to analyze the

status of an additional 1,121 native bees,

without previously existing conservation

statuses, based on current and historical

range as well as behavioral data that allowed

for an assessment. Combining this list with

the existing data on bees with conservation

statuses, we were able to analyze 1,437

species, or 33 percent of all native bee

species described in North America and

Hawaii.

b. Findings

We found that 24 percent of native bees

(347) are imperiled, and population declines

are occurring in 52 percent of native bees

(749).

Many of these bees are endemic or have a

highly restricted range, while others were

once widespread but have been disappearing

over the past several decades. All of these

bees have something in common: Their

habitat is shrinking, and so are their floral

and nesting opportunities. A primary driver

of their declines is agricultural

intensification, which includes habitat

destruction, widespread planting of

monocultures and toxic pesticide use.

There is an urgent need for more research to

better understand the bee species without

current data. The number of imperiled and

declining bee species would undoubtedly be

clarified as higher if additional and current

data were available.

However, we do know that many of these

currently unrankable bees are often found in

areas of great environmental degradation.

Those include monocultures created by the

escalating acreage planted only in crops

such as pesticide intensive corn and

soybeans. More research is urgently needed

to better assess the threats to native bees so

we can understand how to protect them. One

study found that between 2008 to 2013, wild

bee abundance declined across nearly a

quarter of the United States, with

California’s Central Valley and the

Midwest’s Corn Belt ranking among the

lowest in wild bee abundance. [16] This

reduction in bee abundance was due to

intense agricultural use of those areas. [16]

Clearly immediate action is needed if we are

going to stop the widespread decline of

native bees.

Yellow carpet solitary bee (Andrena

blennospematis)

Though it lacks the familiar fuzziness and

bright colors of many other bee species, a

close look at the yellow carpet solitary bee

reveals its dark, olive-green coloring and

pale striped abdomen. [17] This beautiful

bee’s life is so intertwined with the life of

the flower it depends on that they share the

same name, yellow carpet (Blennosperma

nanum). [17][18] The yellow carpet solitary

bee depends solely on this plant genus for

the pollen it needs to produce its offspring;

Page 7: Data-sufficient Bees of North America and Hawaii · PDF file2 Bees are in serious trouble. Native bees indispensable to the health of the natural world are declining globally due to

6

[17][18] the bee’s fate is completely tied to

its specialized flower, and therefore the

health and survival of the pockets of

California vernal pool ecosystems where

they live. [5][18][19][20]

The yellow carpet solitary bee faces myriad

threats, including severe reduction in habitat

and other factors such as pesticide use,

grazing and climate change. Habitat loss and

modification is the primary threat facing the

species because the vernal pool and upland

habitats essential to its life cycle are being

destroyed at alarming rates. [21][22][23] As

much as 90 percent of the extant historic

vernal pool habitat has been lost. [22] Three-

quarters of it was lost by 1997, and by 2005

roughly 137,000 acres of vernal pool

grassland had been lost in California’s

Central Valley. [24][25] An astounding

additional 47,306 acres of vernal pool

habitat was lost just between 2005 and 2012,

despite conservation efforts put in place by

the U.S. Fish and Wildlife Service’s 2005

Vernal Pool Recovery Plan. [22][23] This

loss is mainly due to agriculture,

[22][23][24] with increased pesticide use

posing an escalating threat to the yellow

carpet solitary bee. [26][27][28][29][30]

This loss of the yellow carpet solitary bee’s

habitat is reflected in the reduction of range,

occurrence records and population size.

[17][20][21] These bees are endemic to the

vernal pool and upland habitat of Central

California and the Bay Area [14][17] and

went from occurring in 11 counties to being

confirmed in only one county in the last

decade. [20][21] The loss of the yellow

carpet solitary bee is mirrored in the decline

and possible loss of its specialized host

(Blennosperma spp.), permanently changing

the composition of the vernal pool

ecosystem. [1][5][18][19][20]

Sunflower leafcutting bee (Megachile

fortis)

Photo by Sam Droege / USGS Bee Inventory and Monitoring Lab

The sunflower leafcutting bee is the largest

and most distinctive of all native North

American leafcutting bees. [31] It is one of

the few species within its genus to nest in

the soil, instead of finding a hole in wood to

rear its brood. [9][32] The bee uses its large

mandibles or “bee teeth” to dig into hard

packed soil, excavating a tunnel more than

four times its length. [31]

The floral host for this grassland species is

the sunflower (Helianthus annuus), which

provides a pollen source for the brood.

[14][31][32] This bee times its emergence

and foraging with the bloom time of its

bright-yellow host and could once be seen

darting around sunflower patches from the

Great Plains to Arizona. [33]

The sunflower leafcutting bee’s grassland

habitat is declining across its entire range,

leaving it without forage and nesting habitat.

[14] More than 90 percent of North

America’s natural grasslands have been

converted to agricultural use, putting prairies

Page 8: Data-sufficient Bees of North America and Hawaii · PDF file2 Bees are in serious trouble. Native bees indispensable to the health of the natural world are declining globally due to

among the rarest biomes in America [7] and

replacing natural plant communities with

monocultures of wheat and corn. [33] From

2006 to 2011, more than 1 million acres

(530,000 hectares) of U.S. grasslands were

lost. [34] This conversion caused massive

losses of nectar and pollen resources,

reducing the range and abundance of the

bee. [14][33][35] This important habitat has

been declining since the 1950s, a decline

that is expected to continue, with recent

numbers revealing that states in sunflower

leafcutting bee’s range, [31][36] including

Nebraska, South Dakota and Texas, have the

highest agricultural conversion rates in the

United States. [37]

The sunflower leafcutting bee’s floral host,

the sunflower, is grown commercially in

several states, including North Dakota and

South Dakota. [38] However, sunflower

monocultures can be detrimental to the bee,

because they result in an overall loss of

nesting sites. [39][40] In addition, the use of

pesticides on the sunflower crop has been

shown to harm and even kill solitary bees

like the sunflower leafcutting bees.

[1][14][27] Sublethal impacts caused by

pesticides include decreased fitness, reduced

brood rearing and reduced female

production, all of which lead to smaller

populations that can eventually cause local

to large-scale extinctions. [27][29] Other

threats to these bees are rangeland

grasshopper spraying, grazing and climate

change. [14] If current trends of land

conversion and land-use practices continue,

the already shrinking population of the

sunflower leafcutting bee is projected to

decline by more than 80 percent. [14] Soon

this important creature may disappear from

sunflower fields if steps are not taken to

safeguard its future.

Wild sweet potato bee (Cemolobus

ipomoeae)

Photo by Sam Droege / USGS Bee Inventory and Monitoring Lab

The wild sweet potato bee is the only known

species in the world in its genus. [3] Its

name, Cemolobus, means “lobed snout,”

referring to the three-lobed section on its

face — the only bee to have this particular

feature. [41] It is a floral specialist, foraging

only on morning glory flowers (Ipomoea),

especially wild sweet potato blooms

(Ipomoea pandurata). [3][41][42][43] The

bee emerges and is seen foraging in June

and July, at the peak of flowering season for

its hosts. [41][42]

Both the plant and the bee are found east of

the Great Plains, from Missouri to

Pennsylvania, in deciduous forest or at

forest edges in the eastern United States.

[41][42][43][44][45] The bee was once

prevalent in forested areas, but due logging

and land conversion has decreased in range

and abundance. [46][47] It is also threatened

by agricultural intensification and urban

sprawl: As the bee’s once-pristine habitat

Page 9: Data-sufficient Bees of North America and Hawaii · PDF file2 Bees are in serious trouble. Native bees indispensable to the health of the natural world are declining globally due to

[45] is paved or plowed over, [46] its

nesting and forging opportunities are greatly

reduced, causing population declines.

[4][48] Its floral host is not as fragile as

some other native plants, and can survive in

a built environment, but occurrence records

show that this unique bee does not adapt

well to developed landscapes. [45][49]

The wild sweet potato bee was once most

common in Illinois, yet has not been

collected there since 2001 and before that

had not been regularly collected in the state

since the late 1970s. [45] Many of the

counties in which it was once prevalent are

now expanding towns or agricultural areas.

[37][45][46][50] With its habitat continuing

to be lost to development, this unique and

once ubiquitous insect is now rarely seen.

Gulf Coast solitary bee (Hesperapis

oraria)

Photo by John Bente

The Gulf Coast solitary bee is one of 34 bee

species within the family Melittidae native

to North America [3] and is the only bee

within its genus to be found east of the

Mississippi. [51] The species is also

monolectic, meaning it forages on one plant

and no others: the coastal plain

honeycombhead (Balduina angustifolia),

which provides for all its pollen and nectar

needs. [51][52]

Endemic to a narrow band of barrier islands

along the Gulf Coast, from eastern

Mississippi to northwestern Florida, the bee

nests in the deep sandy soil of dunes and

forages on its specialized flower. [51] It

emerges late in the season, exiting its ground

nest from September to October — the peak

bloom time of the coastal plain

honeycombhead. [51][52] The

honeycombhead is a self-incompatible plant,

meaning it cannot reproduce without the

help of this specialized bee, which transfers

pollen from flower to flower. [51] Both

flower and bee are thus heavily reliant on

each other, and as one declines so does the

other. Due to the bee’s highly restricted host

and range, the species has a high extinction

risk.

The bee’s entire range is estimated to be less

than 38 square miles, and all known

occurrences are in danger from development

and hurricanes. [14] The Gulf Coast solitary

bee only produces one generation a year,

and any disturbance of this small population

or its brood brings it closer to extinction.

[51] Its distribution is becoming

increasingly fragmented by urban growth,

and remaining populations are becoming

increasingly isolated. [51] The bee also has

to contend with unrestricted recreation and

aerial applications of broad-spectrum

insecticides to control biting flies and

mosquitoes. [51] The Gulf Coast solitary

bee has never been found on the mainland

despite its host flower’s presence there,

meaning that if its barrier islands habitat is

further degraded, the bee will cease to exist.

The inevitable results of restricted range,

isolated populations and habitat degradation

are already playing out, as this bee is no

longer found in one of the three counties

where it was known to exist. [14] It is also

disappearing in other portions of its small

range, including Choctawhatchee Bay,

Pensacola Bay and Perdito Bay. [14]

Without prompt action to conserve this

species, it is likely to disappear.

Macropis cuckoo bee (Epeoloides pilosula)

Photo by The Packer Lab-Bee Tribes of the World

The macropis cuckoo bee is the only species

of the cleptoparasitic tribe Osirini present in

the United States and Canada, and is one of

only two species of Epeoloides worldwide.

[3][53] Cleptoparasitism is a form of feeding

in which one bee’s larvae feeds on food

provided for a host larva. [3] The macropis

cuckoo bee is an obligate cleptoparasitic of

Macropis species. [54][55] Cleptoparasitic

or cuckoo bees enter the nest of another bee

(usually host specific) and lay their own egg

in the cell. [3][56] Either the female

cleptoparasite kills the host egg before

leaving, or her larva destroys the host egg as

it matures. [56][57] Hosts of the macropis

cuckoo bee are bees species within

Macropis (M. nuda, M. ciliate, M.

steironematis and M. patellata), from which

its name comes. [53]

The macropis cuckoo bee is a specialist,

dependent upon nest aggregations of its

Macropis hosts, and is often located in or

near yellow or fringed loosestrife

(Lysimachia spp.) habitat. [53][58] The loss

or reduction of its host’s nest is the main

threat to the species. [55] Since Macropis

species are dependent upon yellow or

fringed loosestrife for pollen and floral oils,

they are vulnerable to the loss or reduction

of this plant. [55] Loosestrife plants are

vulnerable to habitat loss and degradation as

well as poor water quality since they’re

found in swamps and along streams and

ponds edges. [55]

The macropis cuckoo bee was historically

distributed in much of eastern and central

North America and southern Canada.

[53][54] A lack of records since 1942 led to

the speculation that this species was extinct

[53][54] until the thrilling discovery of two

males in Nova Scotia in 2004. [53][54] Its

only known locality in the United States

today is in New London, Conn., where it

was discovered in June 2006 [14][59] — the

first record of the bee in the United States

since 1960. [59]

After the bee’s rediscovery, some efforts

have been made to protect it: It was listed as

“endangered” in Connecticut in 2010 [60]

and as “endangered” in Canada under the

COSEWIC in May 2011. [14] The macropis

cuckoo bee is considered “the most

threatened and endangered bee species in

New York (and the Northeast).” [61]

Page 11: Data-sufficient Bees of North America and Hawaii · PDF file2 Bees are in serious trouble. Native bees indispensable to the health of the natural world are declining globally due to

10

Despite more attempts to locate the bee,

unfortunately it has not been found in any of

its previous range in the United States.

[54][59] The story of the macropis cuckoo

provides an important lesson that a species

should not have to decline to the point of

being presumed extinct before receiving

protection. Additional protections are still

needed to ensure that this unique bee

survives and recovers from the brink of

extinction.

Native bees face myriad threats and are in

desperate need of protection to safeguard

their future. They contribute more than $3

billion in fruit-pollination services annually.

[62] And these unique insects, and their

pollination services, are vital to the survival

of ecosystems. Our lives and culture would

be significantly impoverished without these

hardworking, underappreciated and

declining animals.

The data compiled in this report offers a

snapshot of magnitude of threats native bee

species face and the extent of their decline.

These findings are in line with those found

globally and demonstrate the necessity of

more research to fill the data gaps. But what

we already know is troubling and should

inspire us to act: 24 percent of data-

sufficient native bees are imperiled, and 52

percent show population declines. We need

to take aggressive steps to better understand

and protect our precious bee species before

it is too late.
