AGBs belong to the order Coleoptera. The order contains more species than any other order, constituting almost 25% of all known life-forms.
I am having a yearly run in with these insects. They function like a self reproducing electric utility. They top trees, preferentially feeding on new growth at the top of trees: “the terminal leader”.
The AGB is a major drag on my afforestation effort. The establishment of a forest or stand of trees in an area where there hasn’t been forest for centuries is a challenge. All the complexity has been removed, roots, biomass, beneficial fungi, and that has created a zone that is remarkably hostile to young trees, a fragile system.
Complexity is good in natural systems. When people farm, the complex system is removed. The dirt remains, to be used as a media for the desired plant making chemicals to promote growth and chemicals to control insects necessary.
