Banded Alder Borer (Rosalia funebris) on Jul 6, 2021

Submitter does not have a specimen

Description of specimen

I believe this to be a Alder Bore Bettle not its Asian counter part. I read some conflicting things on if it's good or bad for our area. Its segment closest to the head is black and has one white spot

Commentary

Dear Rachel, yes, you are correct. This is our native banded alder borer, Rosalia funebris. Thank you, Helmuth

Location

I am in the Park here in Alton Baker Park
I am wearing a black and white patterned tank top and the bettle found me
He followed me he was so intrigued.
At which point I looked him up to realize the issue and decided to report. I took a picture today. I am sad to report this is not the 1st time I have seen this beetle intown. The 1st time was 2 years ago summer on a phone pole on west 11th down by the Fred Meyers and KFC.
I took a picture then but it was on a different phone. Its definitely the same kind the white spot is in the photos as I looked at the first one a lot not knowing what it was never having seen this bug before. I assumed he ended up intown on a car or something.
