This post is specifically about whether or not invasive European beetles here in the PNW are actually doing harm or not, to people, or to the native organisms. And if they are doing any notable harm, which species are we talking about?, should we be trying to ‘rid ourselves of them?’ Or, should we just let nature eventually run its course with them, and decide whether or not the ‘invaders’ will be here for a long time, or for very little time.
In this post, we are going to include all of the invasive/adventive European Coleopterans that we want to, as long as they are species that were accidentally introduced here in the Pacific Northwest. Oregon, Washington, and British Columbia in this case.
Normally, when I am asked to name the first species that comes to mind when asked for an invasive species here in the PNW, my brain usually goes to Nebria brevicollis, or Pterostichus melanarius, but that is mainly because I have become so used to working with and around them that they are an automatic response sometimes. But I still know there are many other invasive/adventive beetles here, and there are, of course, also many other European beetles that weren’t intentionally introduced to the PNW.
I hope that some or all of the posts/comments/replies in this will be helpful to anyone who is interested in this topic.
I give my best regards,
