Buenos días,
Hoy vuelven las mariposas al blog. Concretamente mariposas nocturnas de la Familia Saturniidae. Pero no avancemos tan deprisa y comencemos por el principio. Hasta el momento, todos los posts anteriores en el blog os he hablado sobre distintas especies de lepidópteros, pero todas de hábitos diurnos. Esta vez me apetecía enseñaros estas fotos que realicé a varias especies de mariposas nocturnas y hablar sobre ellas.
Debido a nuestros hábitos diurnos, los encuentros con mariposas nocturnas son algo menos frecuentes, sin embargo, te sorprenderá saber que éstas superan en número de especies a las diurnas.
Quizás la mala fama que han obtenido por la cultura popular y el vulgar nombre que se les ha otorgado de "polillas" no ayuda a apreciarlas tanto como a las diurnas.
Generalmente, cuando hablamos de "polilla", nos estamos refiriendo a pequeñas mariposas sin apenas colores llamativos que divagan alrededor de un foco de luz durante la noche, pero la realidad dista mucho de las verdaderas mariposas nocturnas. El término polilla corresponde a alguna de las familias de mariposas nocturnas, siendo muchísimo más amplia su taxonomía.
Los lepidópteros nocturnos engloban distintas familias, entre ellas la Familia Saturniidae, a la que pertenecen las especies fotografiadas en este post, entre muchas otras. Los satúrnidos engloban a algunas de las especies de mayor tamaño de todos los lepidópteros, alcanzando incluso 250 mm de envergadura alar algunas de ellas. Algo característico es la carencia de espiritrompa, o bien hay presencia de ella de manera vestigial. Son mariposas productoras de seda. En los próximos posts, profundizaré sobre algunas especies de esta familia, para no hacer este muy extenso.
Good Morning,
Today the butterflies return to the blog. Specifically nocturnal butterflies of the Saturniidae Family. But let's not move forward so fast and start at the beginning. So far, all the previous posts on the blog I've talked about different species of lepidoptera, but all of them with diurnal habits. This time I wanted to show you these photos that I took to several species of nocturnal moths and talk about them.
Due to our diurnal habits, encounters with moths are somewhat less frequent, however, you will be surprised to know that they outnumber the species by day.
Perhaps the bad reputation that they have obtained for the popular culture and the vulgar name that has been granted to them of "moths" does not help to appreciate them as much as to the diurnal ones.
Generally, when we speak of "moth", we are referring to small butterflies with hardly any bright colors that wander around a spotlight during the night, but the reality is far from the true moths at night. The term moth corresponds to one of the families of moths, with a much broader taxonomy.
The nocturnal lepidoptera encompass different families, including the Saturniidae Family, to which the species photographed in this post belong, among many others. Saturnians encompass some of the largest species of all Lepidoptera, reaching even 250 mm in wingspan some of them. Something characteristic is the lack of spiritual spirit, or there is presence of it in a vestigial manner. They are silk producing butterflies. In the next posts, I will delve into some species of this family, so as not to make this very extensive.

Existen algunas características en las que podemos fijarnos para saber si la mariposa que tenemos enfrente es nocturna o diurna, aunque te recomiendo que para asegurarte, te informes en guías específicas y claves dicotómicas que te ayuden a identificarla definitivamente.
Pero a simple vista, si no dispones de ellas, puedes fijarte en dos cosas: las antenas y la postura en estado de reposo.
Las especies diurnas presentan unas antenas que acaban en forma de maza, mientras que en las nocturnas no hay una morfología definida, sino que encontramos antenas filiformes, antenas en forma de pluma o peine, etc.
Otra característica a destacar, y muy curiosa, que distingue a lepidópteros nocturnos y diurnos, es la postura que adoptan en reposo. Mientras que las diurnas generalmente se mantienen con las alas plegadas, las nocturnas lo hacen dejando las alas extendidas. Puedes verlo bien en las fotografías que he realizado, donde reposan sobre una rama con las alas abiertas durante las horas de luz.
There are some features that we can look at to see if the butterfly in front of us is nocturnal or daytime, although I recommend that to ensure you, you are informed in specific guides and dichotomous keys that will help you identify it definitively.
But at first glance, if you do not have them, you can look at two things: the antennas and the position in a resting state.
The diurnal species have antennas that end up in the shape of a club, while in the nocturnal ones there is no defined morphology, but we find filiform antennas, antennas in the form of a feather or comb, etc.
Another feature to highlight, and very curious, that distinguishes nocturnal and diurnal lepidoptera, is the position they adopt at rest. While the diurnal ones are generally kept with the wings folded, the nocturnal ones do it leaving the wings extended. You can see it well in the photographs I have taken, where they rest on a branch with their wings open during the hours of light.
La temperatura de los lepidópteros se corresponde, relativamente, con la del ambiente. En el caso de las mariposas nocturnas, la ausencia de sol durante la noche les ha obligado a evolucionar y conseguir despegar el vuelo sin necesidad de ser calentados por el sol. ¿Cómo lo consiguen? Pues bien, si te fijas, las especies nocturnas a menudo presentan una abundante pubescencia que les proporciona algo de abrigo. Además, pueden mover sus alas generando el calor que requieren para poder iniciar el vuelo durante la noche sin depender de un foco de calor externo, como sí ocurre a las diurnas, que necesitan que el día empiece a transcurrir para poder activarse.
The temperature of the lepidoptera corresponds, relatively, with that of the environment. In the case of night moths, the absence of sun during the night has forced them to evolve and get off the flight without having to be heated by the sun. How do they get it? Well, if you notice, the nocturnal species often have an abundant pubescence that provides them with some shelter. In addition, they can move their wings generating the heat they require to be able to start the flight at night without depending on an external heat source, as it happens with the daylight hours, which need the day to begin to elapse in order to activate.
No me gustaría terminar el post sin mencionar la gran función ecológica que desempeñan estos lepidópteros. Como todas las especies, que no conozcamos el papel que tienen en un ecosistema, no significa que no exista. A pesar de ser algo desconocidas, el valor de las mariposas nocturnas es incalculable.
Tienen un peso importante en la polinización, son muy activas y liban gran cantidad de flores durante la noche e incluso, algunas de ellas, también durante el día, como es el caso de la especie Macroglossum stellatarum (esfinge colibrí), de la cual ya os he hablado en el blog en más de una ocasión.
Otro papel importante es el que desarrollan al formar parte de la base de muchas cadenas y redes tróficas de los ecosistemas, ya que constituyen la base de la alimentación de muchas especies también de hábitos nocturnos como murciélagos, o aves insectívoras.
Por último, y no por ello menos destacable, es el beneficio indirecto, o externalidad positiva, que presentan al ser indicadores biológicos de suma importancia. Cambios en el clima, en la salud ambiental del territorio, en la recuperación o degradación de un ecosistema, etc, pueden ser informados por medio de especies de lepidópteros, en este caso nocturnos.
Espero que os gusten las fotografías y hayáis disfrutado una semana más con el post. Si es así, agradecería mucho que lo compartieras y si te apetece comentar algo, escríbeme en comentarios.

Feliz semana!
I would not like to end the post without mentioning the great ecological function of these lepidoptera. Like all species, we do not know what role they have in an ecosystem, it does not mean that it does not exist. Despite being unknown, the value of moths is incalculable.
They have an important function in the pollination, they are very active and they lend great quantity of flowers during the night and even, some of them, also during the day, as it is the case of the species Macroglossum stellatarum (sphinx hummingbird), of which already I have spoken to you on the blog on more than one occasion.
Another important role is that they develop as they form part of the base of many chains and trophic networks of the ecosystems, since they constitute the basis of the feeding of many species also of nocturnal habits such as bats, or insectivorous birds.
Last but not least, it is the indirect benefit, or positive externality, that they present as being very important biological indicators. Changes in the climate, in the environmental health of the territory, in the recovery or degradation of an ecosystem, etc., can be informed by species of lepidoptera, in this case nocturnal.
I hope you like the pictures and have enjoyed one more week with the post. If so, I would appreciate it if you would share it and if you feel like commenting, write me in comments.
