Help the USDA Locate the Emerald Ash Borer

America’s neighborhoods and forests are under attack. The Emerald Ash Borer (EAB) beetle has destroyed tens of millions of ash trees. Help the USDA protect our trees — and stop the beetle. Look for signs of the EAB in your community and report both positive and negative findings at on behalf of your organization. Then watch your organization rise through the ranks of top beetle detectives.

Identifying the Emerald Ash Borer Beetle (EAB)

From May to August, adult EAB emerge from under the bark of ash
trees and mate. Females lay their eggs in bark crevices and the eggs
hatch into wormlike larvae. The larvae tunnel under the bark to feed
and grow throughout the fall and winter. It is this tunneling and feeding
that eventually kills the tree. You should capture the insects you think
are EAB, place them in a jar and freeze them — this will preserve
the insect for easy identification. You can also search for signs of

• Bright, metallic green

• 1/2” long, flattened back

• Purple abdominal segments beneath wing cover
