Eichen processionary spinner spreads out: danger to life through caterpillars!

Niedersachsen, Deutschland - In recent years, the oak processionary spinner has spread greatly in Germany. Current reports show that he has now also arrived in Saxony. These caterpillars are not only hiked beyond the borders, but also represent a health risk for people. According to Welt RaupenMatitis that can lead to unpleasant allergic reactions.

The oak processionary spinner has been intensively established in various federal states since the mid -1990s. Baden-Württemberg, Bavaria, Rhineland-Palatinate, North Rhine-Westphalia, Hesse, Lower Saxony, Saxony-Anhalt, Berlin, Brandenburg and Mecklenburg-Western Pomerania are particularly affected. The current situation of infestation varies from state to state, but the health effects are currently more serious than the damage to the oaks itself, as also from the SPIEGEL is reported.

The health risk

The brick hair of the oak processionary moth, which is formed from the third larval stage, contain the nettle poison Thaumetopoein.

Thaumetopoein reinforces the symptoms of caterpillar matitis and can also lead to eye irritation. More and more people in affected areas report such complaints.

An interesting aspect of this invasive way is that climate change favors its spread. Earlier spring and mild temperatures promote the early output of the oaks, which favors the oak processionary spinner. Yellow nests of these caterpillars that can reach the size of a football are visible in many oaks.
