We know honeybee are expert pollinator . It ’s why we ’ve descend to look on their services to the degree that we have . And why , by now , we ’ve all surely heard the subject matter that honeybees are in trouble and need our help . Even so , they ’re far from being theonlypollinators around .
In North America alone , there are some 3,600 dissimilar bee species . Around 1,500 of those are east of the Mississippi . “ Further west we have more like 2,500 species , ” mark Matthew Shepherd during the May 2022 webinar,“What Bee Is That ? An Introduction to Commonly Encountered Bees of the U.S. ”
Shepherd is director of education and outreach for theXerces Society for Invertebrate Conservation . He ’s also a groovy spokesman for the countlessotherbees that merit our attention . What follows are some highlighting from Shepherd ’s recent “ What Bee Is That ? ” webinar . ( You canwatch the full webinar recording here . )
Which Ones Are Native Bees?
It ’s light to confuse various native bee with wasps and even sure kinds of flies . As a universal rule , bee are usually hairier . Also , although there ’s a lot of magnetic declination between the thousands of bee coinage , bee have some method acting for carry pollen .
They also have six peg , twopairs of wings and foresighted antennae .
Some of the smallest bees — like sure sweat bee — are only about 0.1 inches long . ( Some bumble bees , on the other hand , measure as much as an column inch and a quarter long ! ) There ’s a lot of variation in how and where these native bees choose to live , too .

Ground-Nesting Bees
“ About 70 percent of our native bees nest in the land , ” Shepherd aver . Some of these include specialist bees like helianthus bees and squash bees . Sunflower bees ( genusSvastra)—emerge in summertime to scrounge almost entirely on sunflowers .
For their part , squelch bees are brightly striped and measure 0.4 to 0.6 in long . From thePeponapisgenus , they ’re particularly well - fit to collect the large pollen grains from squash flowers . As such , they seem in metre with the squash rosiness . ( Leave some bare grime patches near your squash vine works , and squash bees will likely move in . )
Mining bees ( genusAndrena ) are also ground - nesters . There are more than 500 species of these in the U.S. They tunnel into bald-headed patches of globe within supergrass and emerge in late winter . Compared to other bee type , excavation bees are somewhat drab - look . They range from 0.3 to 0.7 inches long .
From the genusMelissodes , manly long - horned bees sport additional - recollective antenna . These ground - squatter are active in summertime and interchangeable in size to minelaying bees .
stripy sweat bees ( genusHalictus ) , small perspiration bees ( genusLasioglossum ) , and metal unripened sweat bee ( genusAgapostemon ) also nest in - ground . Active in summer , some swither bee coinage are so humble they ’re mistaken for gnats .
Tunneling and Cavity-Nesting Bees
“ Most of our other aboriginal bee nest in pre - real tunnels , ” Shepherd continue . “ That might be in dead tree . . . or it might be in a hollow branchlet . ” Among the tunneling bees ? lowly carpenter bees ( genusCeratina)are skinny , shiny , and small — just 0.1 to 0.6 inches long .
A couple of tunneling bees — namely the carder bees ( genusAnthidium ) and the leafcutter bees ( genusMegachile ) go to great nest - building distance . Carder bee scrape away flora fibers for utilisation inside their tunnels . And leafcutter bees , equipped with impressive jaws , remove circular leaf sections with which they line their tunnel .
You ’re likely already conversant with mason or orchard bee ( genusOsmia ) which readily take on manmade nest boxes . There are about 130 mason bee species in the U.S.
If you live in the eastern states , you also probably acknowledge of the tumid carpenter bee ( genusXylocopa . ) Some of these eastward - based tunnelers will endure into solid woodwind instrument — include the walls of our homes ! ( fortuitously , large carpenter bees do n’t seem to have this habit in the West . )
As for the pit - squatter , there are just under 50 bumble bee species ( genusBombus ) in the U.S. These bee are often colorful , velvety , and big — giving enough to occupy abandoned mouse yap and similarly sized arena .

How to Help Native Bees
Encouraging more plant diversity is one of the simplest ways to attract and support these wide-ranging pollinators . That think of allow some “ weedy ” country to thrive and plant many variety of native perennials . This facilitate supply more pollen and ambrosia source for more kinds of bee .
In fact , enquiry lately publishedin the journalProceedings of the Royal Society Bshowed that the overall numbers of important pollinator species grow along with the numbers of different plant life specie available . The researchers used mathematical modeling to analyze data from 11 “ plant – bee visitation networks ” in New Jersey . Rather than considering individual plant mintage , they looked at mixtures of plant life character .
These made up the “ whole - plant community ” in an area .
Within whole - plant community of interests , rarefied aboriginal bee made surprisingly important donation . “ They filled decided operative roles , in this case cross-pollinate dissimilar plant species , ” the researchers noted .
offer more various habitat for aboriginal bees also count for a raft . That can be as simple as leaving some small nude patches of ground in your garden . Being a little less avid with your crepuscle garden cleanupalso make a departure . After all , many kind of bee will tunnel into hollow or soft - centered stems after plants have start to die back .
Give them an assist by leaving some broken , hollow stems in post . instead , you may incorporate these stems into minor brush piles .
Have any dead or choke trees on your prop ? Certain aboriginal bees also will make their habitation in these .
