Is it 'Sailor' or 'Soldier' beetle?
No interactions present.
I've always understood 'Soldier' beetles are red and 'Sailor' beetles are dark based on old infantry and navy uniforms respectively.
This does look like C. rustica but there are a number of very similar species - a useful field key can be found here: http://markgtelfer.co.uk/files/2011/10/A-field-key-to-Soldier-Beetles.pdf
