The most dangerous insect in the Mediterranean region

The Processionary Caterpillar (called this way because of their habit of walking head to tail) is probably the most dangerous insect in the Mediterranean region. They are covered with brittle hairs that provoke severe allergic reactions to humans and could also be lethal to dogs and cats. It also represents a high risk to the trees through the action of the larvae eating pine needles as this can lead to a quick death of the pine tree. 

There may be hundreds of caterpillars seen walking nose to tail, winding along roadways, paths or golfing greens. The caterpillars are covered with brittle hairs, which cause a severe reaction when they come into contact with human skin. The hairs remain toxic even after the caterpillar has died and can also be carried in the air causing respiratory damage if breathed in.
