Emerald Ash Borer

What is an emerald ash borer?
This metallic green-coloured insect accidentally entered North America from Asia. Its larva attacks and kills all native species of ash trees. Since 2002, it has killed millions of ash trees in Canada and in the United States.

What is an ash tree?
Ash trees are usually quite tall and can reach a height that ranges between 15 and 20 meters. They have compound leaves, which can turn from green to yellow in fall, with 5 to 11 leaflets (depending on the species of ash). These leaflets are moderately toothed and may be stalked or sessile. The ash tree also has an opposite branching pattern and can sometimes produce small greenish fruits called samaras.
