After the gales and heavy rain of the last two days, the surface soil of the windowbox is strewn with bits of leaf, flower buds and petals. None of the plants seems to have been damaged, however, and this vegetable detritus will, I suppose, in the fullness of time, create a sort of top-dressing.
I caught a fly too. A little muscid called Coenosia tricolor. I wonder where the third colour is supposed to be.
