Perfect vision🧠🔬 / Vision perfecta🪰 (En-Es)
How many times have we tried to get rid of a fly in our home and it is an almost impossible task, in fact, over the years, tools or devices have been created to kill them more effectively! and of course, by general culture we know that these insects have a very complex vision, some insects even work in an "HD" system so to speak! Today in my experiment we are going to deepen why these animals have such prodigious vision, join me in this experience!🧠🔬
Cuantas veces hemos intentado deshacernos de una mosca en nuestro hogar y es una tarea casi imposible, en realidad con el pasar de los anos se han creado herramientas o aparatos para matarlas con mayor eficacia! y claro por cultura general sabemos que estos insectos tienen una vision muy compleja, algunos insectos hasta trabajan en un sistema "HD" por asi decirlo! hoy en mi experimento vamos a profundizar porque estos animales tienen una vision tan prodigiosa, acompaname en esta experiencia!🕵️♂️🧫🪰
Insects with sensory characteristics🧠/ Insectos con caracteristicas sensoriales🪰🕵️♂️
For this experiment I will use a specimen of the domestic species: (Musca domestica), they are cosmopolitan and almost inhabit the entire earth, in my country they are common from spring to winter due to the climate of Portugal, this dipterous flying insect is characteristic for presenting two wings and its body is divided into three parts: "head, thorax and abdomen", its body is covered by hairs that are not microscopic and that have an important role as a sensory structure, this means that with the body hairs called: (Sensilias ) flies feel, smell and taste!🔬🧫
Para este experimento utilizare un ejemplar de la especie domestica: (Musca domestica), son cosmopolitas y casi habitan toda la tierra, en mi pais son comunes desde primavera hasta invierno por el clima de Portugal, este insecto volador diptero es caracteristico por presentar dos alas y su cuerpo se divide en tres partes: "cabeza, torax y adbomen", su cuerpo esta cubierto por pelos que no son microscopicos y que tienen un papel importante como estructura sensorial, esto quiere decir que con los pelos del cuerpo llamados: (Sensilias) las moscas, sienten, huelen y saborean! 🕵️♂️🪰
In this photo there are two interesting things to highlight, first the aforementioned hairs, which are sensory structures, then also how I apply light to the body of the fly, does it give to see how it has the glowing impression? green with orange and yellow? This is common in arthropods since chitin among other compounds reflects the sun's rays to avoid loss of "water" and the animal die of dehydration! something a bit like bird feathers. They do not properly have a mouth, instead they are called: "mouthparts that are used both for: (sucking, piercing in species that are hematophagous or can be used for licking). This fly vomits "gastric juice" in the food after a external digestion sucks food.🌏🕵️♂️
En esta foto hay dos cosas interesantes que resaltar primero los pelos ya mencionados que son estructuras sensoriales, luego tambien como aplique luz al cuerpo de la mosca da para ver como tiene la impresion que brilla? verde con anaranjado y amarillo? esto es comun en los artropodos ya que la quitina entre otros compuestos refleja los rayos solares para evitar perdida de "agua" y morir deshidratado el animal! algo un poco parecido con las plumas de las aves. No tienen propiamente una boca en cambio se llaman: "piezas bucales que las utilizan tanto como para: (succionar, perforar en las especies que son hematofagos o pueden usarse para lamer). Esta mosca vomita "jugo gastrico" en la comida luego de una digestion externa chupa el alimento.🪰🧫
Compound eyes at 100x🧠/ Ojos compuestos en 100x🪰🕵️♂️
I really liked this scientific article by Mendez, 2011 where they describe the biology of the domestic fly, and as you can see, the eye of a fly is called the compound eye, and within the compound eye we get microstructures called: (ommatidia), however the Flies also have "ocelli" that are three and that are very primitive and rudimentary, they cannot focus and their function is to capture more external light changes, with them "they can activate and deactivate the animal's biological mechanisms" (Jordan, 2013).🕵️♂️🪰
Me gusto mucho este articulo cientifico de Mendez, 2011 donde describen la biologia de la mosca domestica, y como puedes ver al ojo de una mosca se le denomina ojo compuesto, y dentro del ojo compuesto conseguimos microestructuras llamadas: (omatidios), sin embargo las moscas tambien tienen "ocelos" que son tres y que son muy primitivos y rudimentarios no logran enfocar y su funcion es captar mas cambios luminicos externos, con ellos "pueden activar y desactivar mecanismos biologicos del animal" (Jordan, 2013)🔬🧠
Ommatidium🧠/ Omatidio🪰🕵️♂️
As I mentioned, the compound eye has hundreds of ommatidia, I was not able to count them all because it is difficult, but there is scientific work that determined that a domestic fly has about 4000, they are hexagonal in shape and have the property of capturing images in: "slow motion" for So to speak, it also gives them the ability to react to predators, they have a 360 degree field of vision which makes them almost impossible to catch! within the ommatidium there is a cell called: (pigmentary) are specialized cells!🔬🧠
Como lo mencionaba el ojo compuesto presenta cientos de omatidios, no logre contarlos todos porque es dificil pero hay un trabajo cientifico que determino que una mosca domestica presenta unos 4000, presentan forma exagonal y tienen la propiedad de captar imagenes en: "camara lenta" por asi decirlo, ademas les da la capacidad de reaccion ante depredadores, tienen un campo de vision de 360grados los que las hace casi imposible de atraparlas! dentro del omatidio hay una celula llamada: (pigmentarias) son celulas especializadas! 🕵️♂️🪰
I liked the photograph that I took at about 120x magnification because the pigment cells are clearly seen, the ommatidia are nothing more than sensory structures formed by light-receiving cells, with them the fly can determine the presence or lack of light in the environment, and They are even able to distinguish between shades of colors. Although the insect with the best vision could be the dragonfly because it is a hunter, the fly still has extraordinary vision!🧠🕵️♂️🪰
me gusto la fotografia que tome a unos 120x de aumento porque se ven claramente las celulas pigmentarias, los omatidios no son mas que estructuras sensoriales formados por celulas receptoras de luz, con ellas la mosca puede determinar presencia o falta de luz en el entorno, y hasta son capaces de distinguir entre tonos de colores. Apesar que el insecto con mejor vision podria ser la libelula porque es cazadora, la mosca igual tiene una vision extraordinaria!🔬🧫
Another interesting fact🧠/ Otro dato interesante🪰🕵️♂️
The ommatidia allow the fly to create in its "brain" images with shapes and colors, the way the ommatidium works is as follows: "an optical part collects the information as "light", then another part called: "rhabdomerus" transforms light into electrical stimulation, and thus images are created!🔬🪰
Los omatidios permiten que la mosca creen en su "cerebro" imagenes con formas y colores, la forma de como funciona el omatidio es la siguiente: "una parte optica recoge la informacion como "luz", luego otra parte llamada: "rabdomero" transforma la luz en estimulo electrico, y asi se crean las imagenes!🧠🕵️♂️
DNA is an organization to foster and DENSIFY NATURE-APPRECIATION which aims to establish REPORTS OF BIODIVERSITY DATA that is contributed by all of us Hiveans and subsequently cataloged.
Therefore DNA searches for HIGH-QUALITY posts that aim to DESCRIBE and determine the BIODIVERSITY AROUND YOU with added EXPLANATIONS and INFORMATION.

Dunno what kind of eyes mosquitoes have, but I found that if I approach them with my hand slowly, they don't react, as if I'm invisible to them, but if I make sudden motions, they react immediately. Approaching them till my hand is very close and then going in for the kill works far better than swift motions!
I understand that flies have 3 ocelli that help to capture changes in light, that's why it helps them escape faster, I don't know about mosquitoes but I'll make a post about them to see how advanced their eyes are.
