Uninvited and not welcome

I had a lovely day with M, D and little A in the garden. The sunshine was glorious!

We then spotted my beautiful lilies in 3 separate pots were looking like they had been ravaged! Turned to google to discover I am not infested with lily beetles who look pretty but will destroy ever last one of the plants.
I am currently at war with them. Lilies are on of my favourite plants......how dare they....bugger off!!
