Damage, do you want some here: A danger for your garden or your oak groves

The oak processionary caterpillar is a moth that feeds on the leaves of the tree from which it bears the name: the oak. To begin with, the trees lose their leaves (due to the consumption of the caterpillars). The oaks are then fragile and more exposed to pests, diseases and bacteria. The most infested subjects can die indirectly from an infestation of processionary caterpillars.
