Smokey Winged wasp recruited in fight against Emerald Ash Borers

By Deanna Weniger
The emerald ash borer has proved an elusive foe to conservationists. It hides in the tree tops and its larvae stow away under the bark of the ash tree, making early detection difficult.

Scientists have tried a host of methods — purple sticky boxes, yellow pan traps and bark stripping — in a desperate effort to stop the destruction of the invasive wood boring beetle that has killed tens of millions of ash trees in over 20 states.

While the beetle can hide from humans, it’s not as good at hiding from natural predators, such as the smoky-winged beetle bandit, also known as Cerceris fumipennis.

The University of Minnesota Extension office is looking for volunteers to locate and monitor these harmless wasps that build their nests in sandy soil.
