Flies are flying insects and diptera : that is, animals that have a pair of membranous wings and whose mouth allows them to suck food. They have a generally black body, wide head, bulging eyes, legs with suction cups, and a proboscis-shaped mouthpart.
It should be noted that there is not a single type of fly, but rather several species receive this common name. Flies, in their development, go through a complete metamorphosis in four phases (embryo – larva – pupa – imago).
Regarding their reproduction, flies usually lay eggs , although certain species are ovoviviparous . Their habits are diurnal and it is common to find them near excrement or organic matter in the process of decomposition .
A fly or artificial fly , on the other hand, is an element used as bait when you want to fish with a rod. It is a lure that, by imitating insects, pupae or nymphs with its appearance, attracts fish.
The idea of a fly can also be used to refer to goods or, more precisely, cash . For example: “Guys, tonight I'm inviting: today I'm on the fly,” “I ran out of fly, could you lend me some coins?” , “I want to take a vacation but I need more time.”
A fly or a botfly is also called an individual who is annoying , annoying or bothersome : “Your cousin is a fly, she is always bothering you” , “Get out of here, fly! “You have me fed up!” , “Shut up, fly, you're buzzing all day.”
We must not forget that the fly is a very difficult insect to tolerate, since it insistently approaches humans and other living beings in the hottest times to land on their bodies. This makes us fear the possibility of contracting an infection, but it also causes itching and discomfort in general, which often alters our mood and makes us more hot.
Among the diseases carried by flies are the following:
* eye irritation : it has been proven that if we stay for a long time in an environment where flies proliferate, our eyes may become irritated, and even conjunctivitis may arise;
* cholera : it is a fatal disease with symptoms such as vomiting, diarrhea, loss of body fluid and cramps, carried by African flies;
* typhoid fever : this disorder is caused by a bacteria of the salmonella genus and produces weakness, general malaise, constipation and headache;
* dysentery : in everyday speech, it is known as "diarrhea with blood." Its symptoms are strong and can become complicated until it involves the kidney;
* parasitic worms : it is a mild infection but if not treated in time it can lead to major problems.
There are various products to combat fly invasions. The one that poses the least risk to our health is adhesive tape spread with food products, which attract them through the smell; When flies land on the tape, they stick. Since it does not contain any toxic substances, it does not kill them instantly.
There are also aerosols that can be applied to the walls and ceiling, but in this case we are talking about poisons . For this reason, its application should be carried out when no one is in the room, taking special care that children and animals do not enter again until the product has settled.
“The Fly” (or “The Fly” , in its original language), finally, is a film directed by Kurt Neumann . This horror and science fiction film was released in 1958 and was based on a story by George Langelaan where a scientist accidentally combines his DNA with that of a fly.
