The caterpillar animal is one of the most annoying animals. Because when touched with them, then our body will immediately hives, even to cause rash and bumps. This itchiness occurs because the caterpillar has a toxin contained in its feathers. When we touch it, its soft feathers will go into the skin and the poison immediately spread to our body so we feel itch.
The poison present in the caterpillar is a self-defense mechanism of the caterpillar so that when it is attacked by a predator, its toxic fur can help them to defend themselves. Some caterpillars have subtle feathers so that when we touch them, we will only feel the sensation of itching.
Some caterpillars such as Lasiocampidae have sharp fur and the structure resembles a saw blade so it is not just itching, hot and sore sensations will also be felt when touched. Caterpillars can be found in many places, especially in areas with many trees. And unconsciously, caterpillars can be attached to objects close to us, for example in clothes or mattress clothes.
