Shot-hole borers: Polyphagous and Kuroshio

These 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.

Invasive Shot-Hole Borers

Small but Mighty!

This beetle is native to pine forests in the southern U.S., but outbreaks can cause a lot of damage to those forests. Learn more about them below!

Southern Pine Beetle

Small Beetle, Big Impact

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. This particularly beetle comes from a different place in the world and native trees in North America do not have the defenses to keep it at bay.

Redbay Ambrosia Beetle

This Beetle Loves Palm Trees!

This strong beetle got carried to Hawai'i and started chewing the tops of palm trees without a natural predator to check its numbers!

Coconut Rhinoceros Beetle

This Beetle Loves Ash Trees!

They are fine within their northeastern Asia ecosystems. When they arrived to the U.S., the borers put our ash trees in great danger.
