Naturalist downplays ‘hell moth’ caterpillar fears

Media coverage has exaggerated the threat posed by the oak processionary moth caterpillar, according to Danish naturalist and television host Sebastian Klein.

Speaking to DR, Klein said the public fear surrounding the species—dubbed “the caterpillar from hell” by media—is disproportionate to the actual risk. While the caterpillar’s hairs can cause irritation, red bumps, and in rare cases severe reactions requiring medical attention, Klein argued the response has been blown out of proportion.

“It’s simply the worst name you could give an animal,” he said of the media-coined label, urging the use of the species’ correct name: oak processionary moth.

Researchers, including Thomas Pape, a professor at the Natural History Museum of Denmark, have said the species has likely established itself in the country. Pape noted that while efforts to track and control the caterpillar should continue, Denmark will need to adapt, as regions further south have done for years.

Klein acknowledged that targeted control measures in heavily infested areas may be justified but stressed that the caterpillar’s presence would not significantly disrupt daily life. He pointed out that other common species, such as wasps, jellyfish, mosquitoes, and nettles, also cause irritation.

Warning signs have been posted in areas where the caterpillar has been spotted.
