Eventually, herbivory is indirectly affected by light due to leaf based changes of host plants or changes in microclimate. Light based variation in leaf nutritional quality and defense compounds might [...] corre- lated to leaf palatability [24] because mechanical or chemical defenses are often carbon-based [25,26]. Also leaf toughness negatively influences palatability for herbivore insects [27,28]. Negative [...] mean annual precipitation ranges from 474 mm (Artern, Thuringia) to 874 mm (Herzberg, Lower Saxony) based on the reference period from 1961–1990 (Fig 1). Mean annual temperature in the study area was simi-
