Lasius Neoniger
''Lasius neoniger'', also known as the turfgrass ant, Labour day ant, cornfield ant or nuisance ant, is a species of ant in the genus ''Lasius''. Found in North America, the species is common in the eastern United States and Canada, though they can be found all over the continent. They are usually light brown in color, with a slightly darker head. Biology ''Lasius neoniger'' are relatively small ants who prefer to nest in open habitats, including lawns and sidewalks. Colonies of these ants are monogynous and are unwilling to accept other queens or merge with other colonies of the same species. They are one of the many species of ants who tend aphids, who provide the ants with a regular source of sugar and occasionally protein. Colonies have a nuptial flight around the beginning of September, near labour day. The new queens will dig a claustral chamber and hibernate for the winter before starting their new colony the following spring. Ecological impact Due to their preference ...

Carlo Emery
Carlo Emery (25 October 1848, Naples – 11 May 1925) was an Italian entomologist. He is remembered for Emery's rule, which states that insect social parasitism (biology), social parasites are often closely related to their hosts. Early in his career Carlo Emery pursued a course in general medicine, and in 1872 narrowed his interests to ophthalmology. In 1878 he was appointed Professor of Zoology at the University of Cagliari, remaining there for several years until 1881 when he took up an appointment at the University of Bologna as Professor of Zoology, remaining there for thirty-five years until his death. Emery specialised in Hymenoptera, but his early work was on Coleoptera. Prior to 1869, his earliest works were a textbook of general zoology and papers on fishes and molluscs. From 1869 to 1925 he devoted himself almost entirely to the study of ants. Emery published extensively between 1869 and 1926 describing 130 genera and 1057 species mainly in Philogène Auguste Gali ...

Lasius
''Lasius'' is a genus of formicine ants. The type species for this genus is the black garden ant, ''Lasius niger''. Other major members, which live in drier heathland, are the cornfield ant, '' L. neoniger'', and '' L. alienus''. Other species include the temporary social parasites of the ''L. mixtus'' group and the hyper-social parasite '' Lasius fuliginosus''. '' Lasius flavus'' is also a commonly seen species, building grassy hillocks in undisturbed pasture. In the Alps, these mounds - always aligned east to catch the first rays of the rising sun - have been traditionally used by goatherds as natural compasses. Species in the subgenus ''Acanthomyops'', in particular '' L. interjectus'' and '' L. claviger'', are commonly known as citronella ants due to their citronella-like smell. Moisture ants Many ''Lasius'' species, known collectively as "moisture ants" in the United States, make their nests in and around moist rotting wood as well as under rocks. They can infest buildings ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Aphids
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ...

Nuptial Flight
Nuptial flight is an important phase in the reproduction of most ant, termite, and some bee species. It is also observed in some fly species, such as ''Rhamphomyia longicauda''. During the flight, virgin queens mate with males and then land to start a new colony, or, in the case of honey bees, continue the succession of an existing hived colony. The winged version of ants and termites are known as alates. Before the flight A mature ant colony seasonally produces winged virgin queens and males, called alates. Unfertilized eggs develop into males. Fertilized eggs usually develop into wingless, sterile workers, but may develop into virgin queens if the larvae receive special attention. Within a few days after they have emerged (eclosed) from the pupa case, males are "quickly converted into single-purpose sexual missiles." Young queens and males stay in their parent colony until conditions are right for the nuptial flight. The flight requires clear weather since rain is disrup ...

Labor Day
Labor Day is a federal holiday in the United States celebrated on the first Monday in September to honor and recognize the American labor movement and the works and contributions of laborers to the development and achievements of the United States. The three-day weekend it falls on is called Labor Day Weekend. Beginning in the late 19th century, as the trade union and labor movements grew, trade unionists proposed that a day be set aside to celebrate labor. "Labor Day" was promoted by the Central Labor Union and the Knights of Labor, which organized the first parade in New York City. In 1887, Oregon was the first state of the United States to make it an official public holiday. By the time it became an official federal holiday in 1894, thirty states in the U.S. officially celebrated Labor Day. Canada's Labour Day is also celebrated on the first Monday of September. More than 80 other countries celebrate International Workers' Day on May 1, the ancient European holiday of May ...

Soil Respiration
Soil respiration refers to the production of carbon dioxide when soil organisms respire. This includes respiration of plant roots, the rhizosphere, microbes and fauna. Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO2. CO2 is acquired by plants from the atmosphere and converted into organic compounds in the process of photosynthesis. Plants use these organic compounds to build structural components or respire them to release energy. When plant respiration occurs below-ground in the roots, it adds to soil respiration. Over time, plant structural components are consumed by heterotrophs. This heterotrophic consumption releases CO2 and when this CO2 is released by below-ground organisms, it is considered soil respiration. The amount of soil respiration that occurs in an ecosystem is controlled by several factors. The temperature, moisture, nutrient content and level of oxygen in the soil can produce extremely disparate rates of resp ...

Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ...

Insects Described In 1893
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ...
