Listing of insects and bugs that may be found in the state of Oregon.

Keep in mind that insects are not contained by man-drawn borders between states on a map. As such, they may be found beyond the reach listed on our website. Insects are generally drawn to areas by available food supply, weather, environmental factors, water supply and mating patterns. The listing below is a general indicator of bugs that may be found in a given state.
