Green shieldbugs

These two Green shieldbugs seemed to be full of the joys of spring and were moving around this bush for ages, firmly connected in copulation. I imagine it must be similar to the process of hitching up a caravan - "left a bit...right a touch...STOP, you've gone too far!" - but twice as difficult as both 'vehicles' are manoeuvring in reverse. Mind you, a great test of compatibility for a couple attracted to each other!!
