It must be the time of year, but recently, we have had several rhino bettles again. We didn't get many last year, but we have in the past.
These things are so big, you can't be frightened of them. It's not as if they are creepy, or slimy or fluttery. They simply fly into the side of the house (evidently not very agile) and simply crash to the floor.
They are pretty dopey having just crashed, so it is easy to pick them up and put them somewhere safe, ready to recover and fly on.
