Emerald Ash Borer (Agrilus planipennis) is a non-native, invasive insect,
first discovered in Michigan in 2002. Since its arrival, it has destroyed
hundreds of millions of ash trees and cost billions of dollars in management.
1/2 an inch long and 1/8 an inch wide, this tiny pest has 100% mortality rate in unprotected ash trees and is spreading quickly
throughout the Midwest.
