Underneath the bundle was this shiny beetle. I managed to get a pic before it ran away. Look how grainy the top of the wall is where moss and ivy have worked on it!
Then I noticed a whole crowd of beasties: millipedes and more beetles. The picture isn't very well focussed, I'm afraid.
Then they all ran away and I felt like a rotter for removing their roof!
Meanwhile the pond had a certain tadpoley wriggliness about it in all the shallow parts. Sorry, no pic of tadpoles just my favourite pond edging of tiny Opposite-leaved Golden Saxifrage plants.
