Caterpillar Insects

But there is a positive side to the fact that caterpillars actively eat tree leaves. During the years of active breeding of butterflies, water sources become much cleaner. This is due to the fact that there is nothing for the caterpillars to fall to the ground - they eat most of the leaves.

Their bodies are covered with hairs that cause allergic reactions and skin irritation. In order to feel the harm of these creatures, you don't even need to touch them. The fact is that the body of each caterpillar is covered with 700 thousand hairs that are easily and far blown by the wind.

Before turning into butterflies that pollinate plants, caterpillars are recognized as pests. They cause significant damage to agriculture by eating the leaves and fruits of plants. Some of them are poisonous to humans — in 2019, there was an invasion of oak silkworm caterpillars (Antheraea pernyi) on the territory of Germany, Holland and other European countries.
