This beetle's "polyphagous" diet, "fornicatus" breeding, and healthy tree attacks outshine its cousins. It's the black sheep of ambrosia beetles, a global chaos champ.

Meet the polyphagous shot hole borer, a tiny beetle supercharged by human trade, urbanization, and climate change.
From Southeast Asia, this beetle hitchhiked globally, spreading fungal destruction. South Africa's 2017 "outbreak" may hide earlier arrivals, fueled by climate chaos.

"Polyphagous" means "eats many things," but for this beetle, it's about attacking diverse trees, not eating them. The fungus does the feasting.
"Fornicatus" hints at incestuous mating, fueling the shot hole borer's rapid spread. A single female mating with sons creates a female-heavy, invasive army.
The shot hole borer is a delivery system, not the killer. A fungus carried by the beetle chokes trees from within. Understanding this fungal partnership is key.
