The Most Dangerous Type Of Fly In The World Dwells Within America
When it comes to dangerous insects, most people dismiss flies as being harmless. Insects like mosquitoes, bees, wasps and even bed bugs are feared and avoided by Americans. However, there are thousands, if not millions, of insect species that exist in the United States that are rarely encountered by humans. Some of the more obscure insect species that are native to America may also be dangerous. One such obscure, but potentially dangerous insect that is known to exist in the US is a type of fly. This undesirable fly is not like your typical housefly. These flies are known as “black flies” and they distinguish themselves by sucking blood from people and animals. Most people think of flies as nothing more than dirty creatures that are great at annoying people during picnics. It is difficult to imagine an insect that resembles a housefly as being a bloodsucking, pain-inducing and disease spreading menace. Unfortunately, the black fly is all of these things, and its looks almost exactly like a common housefly. These flies are only known for spreading disease in South American and African regions. But black flies are still insects to be feared in America.
This blog has mentioned the disease known as “river blindness” in the past. This disease is spread by black flies in equatorial Africa and in mountainous regions of South and Central America. In the US, only six different species of black fly have been spotted. However, these flies will feed on human blood, and non-biting species have been known to invade people’s ears, throats, noses, eyes and mouths. Although black flies dwelling in America may not cause river blindness, they can cause some people to fall ill.
The seriousness of a black fly bite sustained in America varies from person to person. Some bites are harmless to certain people. Other people can experience symptoms such as, headaches, nausea, swollen lymph nodes in the neck, and high fever. Black flies are located all throughout the US, but people living in the upper midwest are most affected by black flies. Many people living in this region often avoid outdoor activities during late spring and early summer in order to avoid unpleasant black fly bites.
Humans may be safe from dangerous disease agents carried by black flies, but livestock are not safe. Livestock can acquire numerous different disease agents following black fly bites, including protozoa and nematode worms. The suffering that farm animals endure as a result of black fly activity does not stop with infection. Livestock have been suffocated as a result of massive black fly populations crawling into their throats and noses. On rare occasions, farm animals have died from exsanguination (blood loss) after becoming covered in thousands of bloodsucking black flies. Be grateful that humans are spared such a gruesome death.
Have you ever sustained a black fly bite that you know of?
