But luckily, the meltdown was fairly short-lived!
Attending the 50th South of England Show at the South of England Showground in Ardingly yesterday, Camilla was faced with an giant stick insect placed on her arm.
Unable to hide her disdain as she got up close and personal with it while camera bulbs flashed in her face, the 69-year-old allowed onlookers to catch her grimace - a far cry from the composed smile she typically radiates at such events.
Proving she is endlessly a good sport, she kept the insect on her arm for a number of photographs before it was removed.
The stick insect incident comes after Camilla was also seen 'knighting' an actor dressed as a farmer using a leek.
Seems to be all in a day's work for the Duchess!
