Thank you for your question. I believe it is a twice-stabbed stink bug, but since the photo isn't taken directly above the insect, I can't see the pattern very well. Stink bugs in Oregon that are found in crops are listed and shown here: https://www.oregon.gov/oda/shared/Documents/Publications/IPPM/StinkBugGuide.pdf
This type of stink bug isn't harmful, but monitor your plants for damage. Good luck!

Thank you so much for your response.
I have quarantined a few of the small shiny black beetles that were clustered together with slightly larger ones with yellow colour.
Several days later they appear to be maturing into what look like the boxelder bugs in the insect ID charts.
Interestingly they turn yellow for a short time as they mature.
Thanks again for your time & help. Most definitely we will be watching for Berry patch damage.
You're right! An instar I could not find!
Welcome! Isn't research fascinating?
