Grub mosaics: art and IPM

One of our earliest observations was that white grubs, such as masked chafers, appeared to be occurring in areas with the wettest soil. This observation is backed up in the scientific literature, where researchers over the years have shown that many different scarab beetles (including Japanese beetles and masked chafers) prefer to lay their eggs in moister soil, and that the white grubs that hatch from those eggs also have a better chance of survival in moister soil.

How can…
