Sheep will safely graze

No, hang on a minute, them's not sheep, them's sawfly larvae (but they do look a bit like sheep grazing on a cliff top, don't they!) Found them in the botanic gardens in Dundee on Solomon's Seal.
Today's extra is a tiny frog, smaller than my fingernail. There were hundreds of them on the path along the river at Errol, really hard not to tread on them.
