Emerald Ash Borer

In North America the emerald ash borer is an invasive species of beetle, that is highly destructive to ash trees.

This dark metallic green, bullet-shaped beetle was accidentally introduced into the United States and Canada in the 1990s. Since that time, the emerald ash borer has become a major insect control problem in 14 U.S. states, and adjacent parts of Canada.

When the adult emerald ash borer emerges in May to July, the female members of the species lay their eggs in bark crevices, and between layers of bark. When the beetle eggs hatch, in approximately 7 to 10 days, the emerald ash borer larvae will bore into the tree.
