People and butterflies
People admired for centuries in beautiful colors and patterns of butterfly wings. Butterflies depicted in paintings on Egyptian tombs, the medieval Chinese silk, they are also on the canvases of contemporary artists. Play an important role in nature, pollinate plants, leading to the emergence of seeds. Lepidoptera are also used in the fight against bio-species effects, as a classic example was the introduction (importation of new species in areas where they previously did not occur) to Australia, a small cactus moth. This moth feeds on tissue cactus called prickly pear in Australia. This cactus has mastered the great areas of grazing land, making them barren. Cactus moth caterpillars, feeding on this species of cactus, put an end to this problem, by destroying the unwanted plant by calling it rotting tissue.
Moths and butterflies are the food of many animals, including species of economically used by man. They are thus an important part of food depending on the nature, which affect the human population and the populations of plants and animals. Butterflies are sensitive to any change in the environment, and the fact that these insects are easily seen, making them ideal indicators of the state in which there is a biocoenosis. The more species of butterflies in a single location, and the greater the number of individuals, including the ecosystem is healthier. Nor can we forget the role of the silkworm - moths, the cocoons provide us with silk yarn. Although in the age of different types of synthetic fibers, the importance of these insects is becoming smaller, but with natural silk garments is still appreciated.
Many species of moths cause damage to our crops, the caterpillars feed on crops, attack fruit trees and can completely destroy huge areas of forest, especially those. where the only trees are conifers. We have them to blame and fight with them, but we often forget that the g circumstances of this kind are caused by human and rights. Transforming nature created § jednogatunkowe plantations, which are mono-and cultures with a very simple and ideal relationships żerowiskami for these insect species, for which they are hosts. Insects are ideal conditions for breeding at such monocultures, as they often do not encounter there on their natural enemies - their presence is determined, for example, the occurrence of other plant species - and become the cause of massive devastation.
