No interactions present.
With those very sharp 'thorns' projecting from the corners of the pronotum, is this not Spiked Shieldbug Picromerus bidens ?
Not my area of expertise - hence no id entered!

Yes, it might be. It had occurred to me as a possibility. However, I can risk putting an ID with only a "3 bug" rating, knowing that if it's wrong, almost anyone else can correct it. Thank you for showing restraint! It's frustrating when someone with a high rank gives what a bunch of us know is an incorrect ID, but we do not have the power to overturn it. I make no claim to expertise - I'm just a keen amateur with 3 years insect photography and identification behind me who enjoys having a go!
I went for Pentatoma rufipes because of the absence of the banded edge to the abdomen, but I don't know enough to know whether this is a distinguishing feature. However, none of the photos of adult Picromerus bidens on EOL have it, and very few of those here or on Flickr.
Most 5-star individuals are pretty good (and err on the side of caution), but I agree there is a minority of high ranking 'pseudo-experts' who frequently guess IDs, or assume its the one in 'Chinery', without checking the many other options. It is very frustrating.
On the other hand there are many incredibly knowledgeable low ranked individuals who are interested in ID accuracy (rather than 5-star glory at any cost). Unfortunately someone's star-ranking does not always correlate with their expertise.
