Cyclic outbreaks of the larch budmoth (Zeiraphera griseana, hereafter referred to as LBM) have affected the growth of their larch host trees (Larix decidua) in the European Alps. These regular defoliation events have weakened since the 1980s, likely in response to climate change, but recured in 2018. Here, we investigate the LBM activity along two elevational gradients in the Swiss Alps using tree-ring width (TRW) and maximum latewood density (MXD) measurements from 15 sites between 1,400 ...
