Red spider

The garden world

The garden of our house is for us human beings a place for recreation, relaxation, where we can be together with family and friends maybe in a nice party, where we can play our favorite hobby and where to play with our children; however, it is not only this, because if we want to look at it with a scientific eye, it is a real ecosystem. This means that inside it there is such a quantity of life that we do not even imagine it; in fact, going to “zoom in” and considering the very small and microscopic life, we see that the garden is full of many animal and vegetable species unknown to us, such as some bacteria, fungi, insects and much more. The garden, as we write in our title, is a real world; when we live it and maybe we take care of the plants that we have placed inside it, too often we do not pay attention to what may be under our feet or in the earth around the plant we treat. In reality, among the lesser known species that we can meet, there are those of insects. Too often considered as useless and only “disgusting”, they are the result of a pushed and also efficient evolution, which has led them to survive for millions of years and still today they are present in the world with the highest number of species.

Red spider


When in our garden we talk about “red spider” for various reasons, an uproar can be triggered, because under this new one various species are grouped that in one way or another annoy us and our garden. Surely among you there are those who have thought of a mite, there are those who have thought of that species that caused the desiccation of the beautiful flowering plant that they had at the door, and those who have also thought other things; yes, under this clearly popular name, there are various absolutely different species, with the only thing in common that they vaguely resemble a very small spider and also be red in color. But what are they? Well, let’s immediately say that the most common species called “red spider” are three: one of them is absolutely harmless to animals, man and plants and is the most visible because it is larger, the other two are insects that attack various species of plants, in particular one adores the vine and the other adores various flowering and fruit plants. The latter two, however, are absolutely not very visible because they are very small, so at least a magnifying glass is required.

Red travertine spider

The red spider of the travertine is a species of the Arachnid family, and in particular of the Acari section; this is not its scientific name (which instead is distinguished by the denomination of Trombidi), but it is the vulgar name that has been associated with it due to the fact that we typically find it in spring wandering on the brick walls exposed to the sun. It has the shape of a very small spider, with a maximum length of three or four millimeters and a bright red color. It should be noted that it is absolutely harmless both for plants and for animals, even if it is often annoying because it makes real invasions of various walls in spring where maybe we would like to sit; in this regard it must be said that by crushing it even only with your hands, its red liquids are staining, especially for clothes in general but also for the skin. Those who must be afraid of this red spider are some insects (such as Diptera): in fact the Thrombids hunt and feed on these insects, even going so far as to parasitize them with their larvae when they find a colony or in any case a grouping.

Tetranychus and Panonychus

No gentlemen, we are not crazy to put such a title on this paragraph of ours; these two unusual names are the two scientific names of the other species of red spider considered, which are actually the two most annoying for humans. We immediately specify that neither of the two mites (they belong to this group) attacks humans directly in any way, but they annoy him by attacking crops that he cares about or that are in any case important from a commercial point of view. Specifically, Tetranychus attacks soy, a cereal that is becoming more and more important in the world as it is a dietary cereal and indicated for diets low in cholesterol, as well as essential for the Chinese people as it is one of the bases of their diet. Panonychus, on the other hand, is the infesting mite of fruit trees, and in particular of the vine, precious for the grapes and for the wine that is produced with it, from the large internal and external market. Both of these mites attack the lower wall of the leaves, where they are based and where they nest, producing the offspring that will continue in the work of parasitism. If left untreated, especially in young plants, the disease can lead to death by desiccation. The solutions are almost exclusively of a chemical nature, with preventive and other curative products; in both cases, common sense should be used to avoid abusing these unnatural products. place where they are based and where they nest producing the offspring that will continue in the work of parasitism.
