Processionary caterpillars

The oak processionary caterpillar is the larva of a moth. This butterfly lays eggs in the tops of oak trees. The eggs hatch around mid-April. The caterpillar has very small arrow-shaped fire hirs with small barbs. These stinging hairs appear in May and June and can cause complaints for humans and animals.
