The trick is to have a row of brassicas eaten alive by Large White caterpillars, hoping that birds will find them more tasty.

@lionelb@expressional.social I’ve got it!!! Exactly that. I left the uneaten spring greens and the garden us full of cabbage whites! So simple a way to add butterflies - should have thought of it years ago

It is the cicada principle. So many emerge at once that predators can't possibly eat them all.

I suppose the weak point is if you attract vastly more birds than would have been there normally.
