Asian Longhorned Beetle
This beetle hitch-hiked from China in wood packing materials and is now eating hardwood trees without a natural predator to check its numbers!
Walnut Twig Beetle
This tiny beetle and the fungus it carries can greatly affect black walnut trees, a valuable source of wood and delicious nuts!
Redbay Ambrosia Beetle
Ambrosia beetles are wood-degrading insects which live in nutritional symbiosis with ambrosia fungi. Typically, ambrosia beetles are considered beneficial because they accelerate the decay of dead trees, which is important for nutrient cycling in healthy forests. However, these beetles come from a different place in the world and native trees in North America do not have the defenses to keep it at bay.
Coconut Rhinoceros Beetle
This strong beetle got carried to Hawai'i and started chewing the tops of palm trees without a natural predator to check its numbers!
Invasive Shot-Hole Borers
Polyphagous and Kurushio shot-hole borer beetles bore into trees, creating small galleries. Inside these galleries, they lay eggs and “farm” a fungus (Fusarium spp.), which is their main food source. The fungus colonizes the trees' vascular systems, blocking transport of water and nutrients.
