Lea Nash was talking to her neighbor about Oregon’s newest pest when one flew into her neck — or so she thought. …The bug was a brilliant metallic green, just like the invasive emerald ash borer, scientific name Agrilus planipennis. But with just a bit more information at her disposal, Nash may have noticed the black spots on her specimen’s wing covers. …[It] was later identified a western cedar border, scientific name Trachykele blondeli, another in the buprestidae family of wood-boring beetles often called “jewel beetles” for their metallic hues. …Though the western cedar borer is one of the insects most commonly confused with emerald ash borer, it’s an Oregon native and doesn’t create the kind of ecological disaster local foresters now are expecting its invasive cousin to cause. …To the layperson, many other metallic green beetle species look similar to invasive emerald ash borer, said ODF forest entomologist Christine Buhl.
