A Common Black Ground Beetle about 15mm, 1/2 inch, long waiting patiently until I had finished.
Next, take it back outdoors where it belongs. Went to the kitchen and fetched an empty jar kept for such occasions. Back to the bathroom in time to see it disappearing from view. Just as I was about to give up it reappeared at top speed scurrying back across the bathroom floor. Managed to plonk the upturned jar over it and slide a piece of cardboard underneath. Captured. Unlock the doors I had secured for the night. Gently tip beetle on the lawn, followed by the four legged supervisor to see what was going on. Wildlife back where it belonged. Lock up again and so to bed.
