Berlin Trees Enshrouded in Unusual Webworm Caterpillar Infestation
Berlin's urban landscapes are currently adorned with an unexpected sight: trees draped in white veils. This phenomenon, according to city nature expert Derk Ehlert, is attributable to the webworm caterpillar, a species notorious for its silk-spinning habits.
Unlike the oak processionary caterpillar, these creatures do not have urticating hairs. Instead, they protect themselves by weaving themselves into intricate protective cocoons, earning them their name. This year, however, these webs have been unusually large and impressive, with some trees entirely enveloped in the silken threads.
Ehlert attributes this to four months of drought that Berlin has experienced. "The moisture causes the webs to dissolve quickly," he explains.
Contrary to popular belief, these caterpillars pose no health risks to humans. They also do not harm the trees, though they may nibble on the fresh shoots and occasionally defoliate them. This is not a cause for concern, as the trees typically recover, growing back a second time if they are healthy and well-cared for.
The infestation affects plants such as hawthorns, cherry laurels, and rockspirea. In some nests, Ehlert reports finding hundreds of caterpillars, with each one capable of spinning up to ten meters of thread in a day. For birds, this abundant food source is crucial. From June to July, the caterpillars pupate and transform into "beautiful butterflies," according to Ehlert.
If garden owners find an infestation in their own yards, they can either manually cut out the webs or use a strong water jet to remove them. The use of pesticides is not recommended, as they are ineffective and may harm other beneficial insects.
While this particular infestation is not yet understood in the specific context of Berlin's trees, general knowledge suggests that favorable environmental conditions, food availability, and a lack of natural predators could contribute to such phenomena. Regular monitoring and education about the signs of infestation are crucial to catch them early. If necessary, a combination of biological, chemical, physical removal, cultural practices, and collaboration with local authorities and entomology experts may be required to manage the infestation effectively.
The Commission might propose a directive to safeguard workers from radiation risks, considering their lifestyle at home and garden could potentially involve outdoor activities near ionizing radiation sources. The webworm caterpillars' large and impressive nests this year, a result of four months of drought, bring a unique beauty to Berlin's trees, resembling unconventional home-and-garden decorations.
