<div class="text-justify">For some time I was trying to decipher a species that I got in a stagnant water sample a few months ago, but I did not have enough clues to identify it, again in my research I captured something that moved very fast in the water and that had a " propeller tail", in my twisted head I even imagined that it was some kind of alien!! but if so, surely I wasn't writing this xD, the thing is that this "mysterious" creature led me to take a final step towards the identification of that even stranger animal! Join me to see who it is!🤔👨‍💻🧠

#

Hacia algun tiempo que estaba tratando de descifrar una especie que me consegui en una muestra de agua estancada hace algunos meses, pero no tenia pistas suficientes para identificarla, nuevamente en mi investigacion capture algo que se movia muy rapido en el agua y que tenia una "cola propulsora", en mi cabeza retorcida hasta imagine que era alguna especie de alien!! pero de ser asi, seguramente no estaba escribiendo esto xD, la cosa es que esta criatura "misteriosa" me llevo a dar un paso final a la identificacion de aquel animal aun mas extraño! acompañame para ver de quien se trata!🧠🔬🧫</div>

<div class=pull-left>It all started here, when I captured this animal that was not microscopic at all since it could be seen without using the "magnifying glass", but I had no idea what it was, searching the internet I couldn't find any clues that would help me find the identification and my only intuition was it must be the larval stage of some insect! consult some biologist friends who also shared my opinion! but the subject would not close for me and I would continue investigating until I managed to identify it! I was so worried about his "tail" because it was retractable, and I thought... Could it be some accessory for locomotion? Is it some feeding system? When I captured this "mysterious alien" its tail was very similar to the one I had found months before...🤯😮🤔🤔

</div><div class=pull-right>Todo comenzo aqui, cuando capture este animal que no era microscopico del todo ya que podia ser visto sin usar la "lupa", pero no tenia idea de lo que era, buscando en internet no conseguia ninguna pista que me ayudara a dar con la identificacion y mi unica intuicion fue debe ser el estado larvario de algun insecto! consulte a unos amigos biologos quienes tambien compartieron mi opinion! pero el tema no cerraria para mi y seguiria investigando hasta lograr identificarlo! me inquietaba tanto su "cola" porque era retractil, y pense... Sera algun accesorio para locomocion? sera algun sistema de alimentacion? cuando capture este "alien misterioso" su cola era muy parecida a aquel que habia encontrado meses atras...❗❓❓</div>

<div class=pull-left>I was prepared to decipher my mystery, observing their morphology they both had a retractable tail, but their functions did not seem similar, while in my "mysterious alien" the tail was propulsive in that other specimen the tail did not provide movement, and following my instinct everything it pointed to different larval stages, one more developed than the other... And suddenly I got this on the internet and I was closer to ending this mystery!😮🤔

</div><div class=pull-right>Estaba preparado para descifrar mi misterio, observando su morfologia ambos tenian una cola retractil, pero sus funciones no parecian similares, mientras en mi "alien misterioso" la cola era propulsora en aquel otro especimen la cola no le proporcionaba movimiento, y siguiendo mi instinto todo apuntaba a estados larvarios diferentes uno mas desarrollado que otro... Y de pronto consegui esto en internet y ya estaba mas cerca de acabar con este misterio!🤔🤔</div>

<div class=pull-left>Wow, what a great similarity there was between my specimen and this reference found on the internet, the mystery of "alien" was closer to being deciphered, we can see that the animal can measure about 2 centimeters, it is aquatic and everything corresponds to my specimen! but none of this would have been possible without these new photos, as I am a good detective it was time to understand what each structure of my "alien" was for...🤔🕵️‍♂️👨‍🏫

</div><div class=pull-right>Vaya que gran similitud habia entre mi especimen y esta referencia encontrada en internet, el misterio de "alien" estaba mas cerca de ser descifrado, podemos ver que el animal puede medir unos 2 centimetros, es acuatico y todo corresponde a mi ejemplar! pero nada de esto hubiese sido posible sin estas nuevas fotos, como soy un buen detective era hora de entender para que era cada estructura de mi "alien"...👨‍🏫👨‍🎓</div>

<div class=pull-left>Wow wow... It turns out that our friend has a "tail" with a very interesting function, and it is a "spiracle" that is, a conduit where gaseous exchange takes place, basically here the "alien breathes", already in this point had identified our friend! but now I needed to discover more clues to better understand his morphology! What most caught my attention from our "alien" were his eyes! and there is an animal with "eyes" similar to this one!🔬🔬🧠💨

</div><div class=pull-right>Vaya vaya... Resulta ser que nuestro amigo tiene una "cola" con una funcion bastante interesante, y se trata de un "espiraculo" osea un conducto donde se realiza el intercambio gaseoso, basicamente por aqui el "alien respira", ya en este punto habia identificado a nuestro amigo! pero ahora necesitaba descubrir mas pistas para entender mejor su morfologia! lo que mas capto mi atencion de nuestro "alien" fueron sus ojos! y hay un animal con "ojos" similares a este!🤯🤯</div>

<div class=pull-left>So, remembering my zoology II lectures at the university, clearly this is a "larval stage of a diptera", a "diptera" is a group of insects that have "two wings", such as flies, among others! After I have discovered that it is an insect, it is time to identify it. To do this, I must know which one lays its eggs in the water and which species has a larval stage like our animal with a "breathing tail". So I had to access a very interesting website that helps us with these problems!🤔🤔

</div><div class=pull-right>Entonces recordando mis aulas de zoologia II en la universidad claramente esto es una "fase larvaria de un diptero", un "diptero" es una agrupacion de insectos que tienen "dos alas",  como por ejemplo las moscas, entre otros! luego que ya he descubierto que se trata de un insecto es hora de identificarlo, para ello debo saber cual coloca sus huevos en el agua y cual especie presenta un estado larvario como nuestro animal con "cola respiradora". Por lo que tuve que acceder a una web bastante interesante que nos ayuda con estos problemas!🔬👨‍💻👨‍🏫</div>

<div class=pull-left>We have now managed to identify our species, it is a larva of (Syrphidae), what are known as flower flies, they are common here in Portugal and various parts of the world! because they are flies that is why we observe their eyes with (omatidia) that would be individual eyes, therefore a compound eye of a fly can have more than 100 individual eyes! and that is why it is difficult to catch a fly!😮😮

</div><div class=pull-right>Listo hemos conseguido identificar nuestra especie se trata de una larva de (Syrphidae), lo que se conocen como moscas de las flores, son comunes aqui en Portugal y varias partes del mundo! debido a que son moscas por eso observamos sus ojos con (omatidios) que serian ojos individuales, por tanto un ojo compuesto de una mosca pueden haber mas de 100 ojos individuales! y es por eso que es dificil capturar una mosca!👩‍🏫🤯🧠 </div>

<div class=pull-left>And we found our specimen it is (the drone fly), did you know that it was originally from Europe and was introduced in the United States? Apart from discovering that our "alien" is a fly, we also discovered that it is invasive and quite resistant and well adapted! Do you want even more interesting information? this insect performs a kind of "mimicry" over time, it resembled the honey bee, which we know has a very painful sting, therefore the fly is confused with the bee to confuse its predators! Sorry? that???😮😮

</div><div class=pull-right>Y dimos con nuestro ejemplar se trata de (la mosca zangano), sabias que era originaria de europa y se introdujo en estados unidos? aparte que descubrimos que nuestro "alien" es una mosca tambien descubrimos que es invasora y bastante resistente y bien adaptada!, quieres un dato aun mas interesante? este insecto realiza una especie de "mimetismo" con el tiempo se parecio a la abeja de la miel, que sabemos que tiene una picadura muy dolorsa, por tanto la mosca se confunde con la abeja para confundir a sus depredadores! disculpa? que???🤯</div>

<div class=pull-left>I want you to differentiate the two photos that I show you! Basically we see a high resolution view of the fly's eyes, as you can see when I stimulate it with light they look like that! We shouldn't worry about the fly, it's harmless, but don't be overconfident if you ingest water contaminated with the larvae, you could suffer from "myiasis" "which is a parasitic infection with fly larvae."😮😮

</div><div class=pull-right>Quiero que diferencies las dos fotos que te muestro! basicamente vemos una vista de alta resolucion de los ojos de la mosca, como puedes ver cuando lo estimulo con la luz adquieren ese aspecto! no debemos de preocuparnos la mosca es inofensiva, pero no te confies si llegas a ingerir agua contaminada con la larva puedes sufrir de "miasis" "que es una infeccion parasitaria con larva de mosca".😨😱</div>
