The devil rides out

A long black beetle undulated across the path in front of me and I recognised it as a devil's coach horse Ocypus olens.  These  carnivorous rove beetles rear up their tails like scorpions when they feel threatened and while the tail doesn't have a sting in it their mandibles can give you a nasty nip.  I've seen this display before but never noticed the two  little bright white 'fangs' which are the scent glands, capable of producing a foul smell as a defence.  Mounted on top of the  raised tail they look like eyes  - I wonder if they have a mimicry function too. (Another view of this in the extra.) 
 In Irish folklore  the beetle was thought to direct a curse by pointing its tail and you'd be forgiven seven sins if you killed one.  It also  provided the theme of a 1979 pot-boiler with the strap line  A winged terror flies by night feeding on death and destruction (worth checking out the cover illustration).
Give a beetle a bad name and crush it? (Needless to say I didn't.)
