The oak processionary caterpillar,
or Eikenprocessierups in Dutch, is a pest that causes significant damage to oak
trees in Europe. The caterpillar's hairs contain a toxic protein called
thaumetopoein that can cause skin irritation, respiratory problems, and
anaphylactic shock in some individuals. The species is most prevalent in the
Netherlands, Belgium, and Germany, where it poses a significant health hazard.
Oak trees are an essential part of many ecosystems and have significant cultural
and historical value. The genus Quercus is home to over 500 species of trees
and shrubs, and their conservation is crucial for biodiversity and the
environment.
