Information:  - The Canadian Prairies is a region in western Canada, which may correspond to several different definitions, natural or political. Notably, the Prairie provinces or simply the Prairies comprise the provinces of Alberta, Saskatchewan, and Manitoba, as they are partially covered by prairie (grasslands). In a more restricted sense, the term may also refer only to the areas of those provinces covered by prairie; their portions of the physiographic region known as the Interior Plains. Prairie also covers portions of northeastern British Columbia, though that province is typically not included in the region in a political sense.  - Amegilla is a large genus of bees in the tribe Anthophorini. Several species have blue metallic bands on the abdomen, and are referred to as "blue-banded bees".  - The Centridini are a tribe of large apid bees, many of which possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. The floral oils are often gathered from plants of the family Malpighiaceae, though other plants may be visited. The oil-collecting species typically have "combs" composed of closely spaced, flattened, blunt bristles on the margins of the first tarsal segments of the front and middle legs; others may have velvety "pads" to absorb the oils. They also commonly gather plant resins for use in nest cell construction. They have a tiny pterostigma in the forewing, the female scopa is very bushy, and the first flagellomere of the antenna is often longer than the scape.  - Ohio is an Eastern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus.  - Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 5th most populous state and 25th largest state in terms of land area, and is often noted as a microcosm of the entire country. The word "Illinois" comes from the Algonquin word for "tribe of superior men". With Chicago in the northeast, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a diverse economic base and is a major transportation hub. The Port of Chicago connects the state to other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River. For decades, O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms and politics.  - In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world.  - The bee genus Anthophora is one of the largest in the family Apidae, with over 450 species worldwide in 14 different subgenera. They are most abundant and diverse in the Holarctic and African biogeographic regions. All species are solitary, though many nest in large aggregations. Nearly all species make nests in the soil, either in banks or in flat ground; the larvae develop in cells with waterproof linings and do not spin cocoons. Males commonly have pale white or yellow facial markings, and/or peculiarly modified leg armature and hairs. "Anthophora" individuals can be distinguished from the very similar genus "Amegilla" by the possession of an arolium between the tarsal claws.  - The Great Plains is the broad expanse of flat land (a plain), much of it covered in prairie, steppe and grassland, that lies west of the Mississippi River tallgrass prairie states and east of the Rocky Mountains in the United States and Canada. This area covers parts, but not all, of the states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, Minnesota, Iowa and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The region is known for supporting extensive cattle ranching and dry farming.  - Texas is the second largest state in the United States by both area and population. Geographically located in the south central part of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast.  - Missouri (see pronunciations) is a state in the Midwestern region of the United States, achieving statehood in 1821. With over six million residents, it is the eighteenth most populous state and host to the mean center of United States population. The largest urban areas are St. Louis, Kansas City, Springfield, and Columbia. The capitol is in Jefferson City on the Missouri River. The state is the twenty-first most extensive by area and is geographically diverse. The Northern Plains were once covered by glaciers, then tallgrass prairie, and now the deep soils yield great agricultural productivity. In the South are the Ozarks, a forested highland, providing timber, minerals, and recreation. The Mississippi River forms the eastern border of the state, eventually flowing into the swampy Missouri Bootheel.  - New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the union as the 47th state on January 6, 1912. It is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, and the sixth-least densely populated of the 50 United States.  - The Melectini are a tribe of medium - to large - sized apid bees found essentially worldwide . They are brood parasites of the related typical digger bees ( Anthophorini ) and occasionally visit flowers e.g. in prairie landscapes of the United States . As in other cuckoo bees , females can be easily distinguished from those of their hosts by the lack of scopae and other pollen - collecting adaptations , as well as lacking prepygidial fimbria and basitibial plates . Their body hair is rather short and on the abdomen lies flat against the exoskeleton . They may , therefore , be difficult at first glance to distinguish from the Nomadinae , but the details of their wing venation are characteristic : the marginal cell is shorter than the first two submarginal cells , and the second abscissa of vein M + Cu is extremely short , with the cells it connects being almost adjacent to each other . The jugal lobes are very small , less than half as long as the vannal lobes .  - Saskatchewan (or ) is a prairie and boreal province in west-central Canada, the only province without natural borders. It has an area of , nearly 10 percent of which is fresh water, composed mostly of rivers, reservoirs, and the province's 100,000 lakes.  - Wyoming is a state in the mountain region of the western United States. The state is the tenth largest by area, the least populous and the second least densely populated state in the country. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. Cheyenne is the capital and the most populous city in Wyoming, with a population estimate of 63,335 in 2015. The state population was estimated at 586,107 in 2015, which is less than the population of 31 of the largest U.S. cities.  - Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees. The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees (also used for honey production), carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups. Many are valuable pollinators in natural habitats and for agricultural crops.  - Kansas is a U.S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name (natively "") is often said to mean "people of the wind" or "people of the south wind", although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison.  - The Anthophorini are a large tribe in the subfamily Apinae of the family Apidae. Species in this tribe are often referred to as digger bees, although this common name is sometimes also applied to members of the tribe Centridini. It has over 750 species worldwide that were previously classified in the family Anthophoridae; the vast majority of species are in the genera "Amegilla" and "Anthophora".  - Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.  - Nebraska is a state that lies in both the Great Plains and the Midwestern United States. The state is bordered by South Dakota to the north, Iowa to the east and Missouri to the southeast, both across the Missouri River, Kansas to the south, Colorado to the southwest and Wyoming to the west. Its area is just over 77,220 sq mi (200,000 km) with almost 1.9 million people. Its state capital is Lincoln. Its largest city is Omaha, which is on the Missouri River.  - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.  - Alberta is a western province of Canada. With an estimated population of 4,196,457 as of July 1, 2015, it is Canada's fourth-most populous province and the most populous of Canada's three prairie provinces. Its area is about . Alberta and its neighbour Saskatchewan were districts of the Northwest Territories until they were established as provinces on September 1, 1905. The premier has been Rachel Notley since May 2015.  - Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, southern Brazil and Uruguay as well as the steppes of Eurasia. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, somewhat hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Ohio, Indiana, Wisconsin, and western and southern Minnesota. The Central Valley of California is also a prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta.  - The Apinae are the subfamily that includes the majority of bees in the family Apidae. It includes the familiar "corbiculate" (pollen basket) bees  bumblebees, honey bees, orchid bees, stingless bees, and the extinct genus "Euglossopteryx". It also includes all but two of the groups (excluding Nomadinae and Xylocopinae) that were previously classified in the family Anthophoridae.  - In geography, a plain is a flat area. Plains occur as lowlands along the bottoms of valleys, coastal plains and as plateaus or uplands at high elevations. In a valley, a plain is enclosed on two sides but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains or cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometime termed a gap). Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.  - Uruguay, officially the Oriental Republic of Uruguay, is a country in the southeastern region of South America. It borders Argentina to its west and Brazil to its north and east, with the Río de la Plata (River of Silver) to the south and with the Atlantic Ocean to the southeast. Uruguay is home to an estimated 3.42 million people, of whom 1.8 million live in the metropolitan area of its capital and largest city, Montevideo. With an area of approximately , Uruguay is geographically the second-smallest nation in South America, only larger in size than Suriname.  - California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County.  - Indiana is a U.S. state located in the midwestern and Great Lakes regions of North America. Indiana is the 38th largest by area and the 16th most populous of the 50 United States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th U.S. state on December 11, 1816.  - The Pampas (from Quechua "pampa," meaning "plain") are fertile South American lowlands, covering more than , that include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos and Córdoba; most of Uruguay; and the southernmost Brazilian State, Rio Grande do Sul. These vast plains are a natural region only interrupted by the low Ventana and Tandil hills near Bahía Blanca and Tandil (Argentina), with a height of and , respectively.  - Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton.  - Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system.  - Wisconsin is a U.S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, and Lake Superior to the north. Wisconsin is the 23rd largest state by total area and the 20th most populous. The state capital is Madison, and its largest city is Milwaukee, which is located on the western shore of Lake Michigan. The state is divided into 72 counties.  - Minnesota (locally ) is a state in the midwestern and northern regions of the United States. Minnesota was admitted as the 32nd U.S. state on May 11, 1858, created from the eastern half of the Minnesota Territory. The state has a large number of lakes, and is known by the slogan "Land of 10,000 Lakes". Its official motto is "L'Étoile du Nord" (French: "Star of the North"). Minnesota is the 12th largest in area and the 21st most populous of the U.S. states; nearly 60 percent of its residents live in the MinneapolisSaint Paul metropolitan area (known as the "Twin Cities"), the center of transportation, business, industry, education, and government and home to an internationally known arts community. The remainder of the state consists of western prairies now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed and settled; and the less populated North Woods, used for mining, forestry, and recreation. Minnesota is known for its progressive political orientation and its high rate of civic participation and voter turnout. Until European settlement, Minnesota was inhabited by the Dakota and Ojibwe/Anishinaabe. During the 19th and early 20th centuries, the large majority of the European settlers emigrated from Scandinavia and Germany, and the state remains a center of Scandinavian American and German American culture. In recent decades, immigration from Asia, the Horn of Africa, and Latin America has broadened its historic demographic and cultural composition. Minnesota's standard of living index is among the highest in the United States, and the state is also among the best-educated and wealthiest in the nation.
