Question:

Do bot flies live in the United States?

Answer:

Human bot flies do not live in the US. They live in Central and South America and Mexico. Other types do live in the US though.

More Info:

The Oestridae are a family of flies variously known as bot flies, warble flies, heel flies, gadflies, and similar names. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. The human botfly, Dermatobia hominis, is the only species of bot fly known to parasitize humans routinely, though other species of fly do cause myiasis in humans.

Botfly Parasites Zoology Biology

The horse guard wasp, Stictia carolina, is a type of sand wasp from the eastern United States which preys primarily upon horse flies. It is a large, colorful, fast-flying wasp, one of 28 species in the genus Stictia (which occur throughout North and South America), all of which have similar biology. A female wasp of this species may take anywhere from 30 to 60 flies as food to provision each one of her nests; she makes a new nest for every egg she lays. Nests are simple burrows some 15 cm deep, with a single enlarged chamber at the bottom. An egg is laid in the empty chamber, and the female wasp brings back paralyzed flies until the chamber is full, at which point she closes the nest and begins another. It is common for numerous females to excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations.

It is noteworthy that horses and cattle are not disturbed by the presence of these wasps, despite their rapid flight and loud buzzing, even though the same animals can be very skittish in the presence of horse flies or bot flies. Nonetheless, these beneficial wasps are intimidating to many horse owners, who, if not familiar with them, may take measures to eliminate the wasps, thus exacerbating their problems with horse flies.

Myiasis

A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.

Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.


Central America

Central America (Spanish: América Central or Centroamérica) is the central geographic region of the Americas. It is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. When considered part of the unified continental model, it is considered a subcontinent. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Central America is part of the Mesoamerican biodiversity hotspot, which extends from northern Guatemala through central Panama. It is bordered by Mexico to the north, the Caribbean Sea to the east, the North Pacific Ocean to the west, and Colombia to the south-east which is also the most southern point of North America.

Central America is an area of 524,000 square kilometers (202,000 sq mi), or almost 0.1% of the Earth's surface. As of 2009, its population was estimated at 41,739,000. It has a density of 77 people per square kilometer.

South America is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be considered as a subcontinent of the Americas.

The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.

Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
