Submitter does not have a specimen

Description of specimen

Bright metallic green beetle like insect at least an inch long

Commentary

Thank you for your report! EAB is only about 1/2" long, and only attacks ash and European olive trees. Their grubs make S-shaped galleries just under the bark.

There are many green insects in Oregon that are not pests. Without a photo, I'm not sure what you saw. Thanks for being on the lookout!

Location

Just off north side hiway 42 east of bridge oregon near weeping willow lane junction with hiway 42.
The area was logged for the large fir trees and many madrone logs were left in decks. There are multiple species of mature hardwood still standing, including madrone. While cutting old madrone logs and splitting, what looked like emerald ash borers were seen on several occasions bored intp the madrone wood. I don't recall ever seeing this insect before.
