A caterpillar is the larva of a certain kind of insect. The caterpillars constitute a phase of the development of butterflies and other lepidoptera animals. They usually exhibit an interesting variety of colors that covers their body .

Soft structure, the caterpillars have the segmented body . They mobilize by crawling and feed mostly on plants . Although they have six eyes, their sense of sight is not very developed and they are guided with antennas. Beyond the shared characteristics, caterpillars can be quite different from each other according to the species in question.

It must be stated that there are various types of caterpillars. Thus, for example, we find the so-called processionary caterpillar of the pine tree, which is characterized by being very sensitive to cold and living in forested areas.

Although its sides are gray, the rest of the body is black and also has red hair, called trichomes, which come to act as its defense weapon. And it is that these can cause blunt conditions that are shown through allergic reactions.

The notion of caterpillar is also used to name different types of plants. The Eruca vesicaria , which belongs to the cruciferous group, can be known as a caterpillar, arugula or ruca . This herbaceous type plant is used as a salad ingredient and is also used to season pizzas and other foods .

In the same way, we cannot forget that precisely with that plant a sauce is produced in some countries that is also called caterpillar. It is a sauce that is prepared using other ingredients such as sugar, vinegar or honey.

The Asphodelus fistulosus or gamoncillo It is also called a caterpillar in some regions. It is part of the xantoroeáceas and is qualified as an invasive species in the American territory.

No less important is that within the accessibility sector there is also what is known as a stair lift. It is a portable device that allows people in wheelchairs to overcome steps, stairs and other architectural barriers in a simple way.

If it receives that name it is precisely because its articulated chain reminds of the movement of the mentioned larva. Nowadays it has become one of the most demanded and used accessibility systems. Why? Because it has an important series of benefits compared to other items, such as an economical price, absolute security, which can be folded, which is easily transportable and hardly occupies space.

It is known as a caterpillar, finally, to a certain chain which is used on the wheels of some vehicles so that they can move on uneven surfaces. From this device, we talk about the caterpillar traction of tanks, trucks, etc.

Thanks to this traction, the vehicles of war they can advance almost any terrain beyond the unevenness and obstacles they encounter. The caterpillar, in this sense, is key to achieving mobility.
