Thanks to Gardeners’ World ...

I now know whose hidden beneath that bent over leaf! It a caterpillar! Now I know already that it’ll be a cabbage white and we should probably squash it BUT we want our new bed to attack wildlife, and the fact a butterfly came and laid its eggs is well ... what we wanted it!

There’s two others on the mint ... so I’ve taken that leaf off the salvia and hid it in the mint with the others!
