scarcity of butterflies
I have been looking at food plants for caterpillars and most seem to be wild/native/weeds, not things we grow much in our gardens. Could the decline in butterflies and moths be due to the fact that their caterpillars can't feed and therefore survive? Nice to encourage butterflies to our gardens but no good if their babies can't survive. There is some talk now about re-wilding, but it should be more than talk, more about doing. There are lots of pieces of brownfield or rough, unused ground, perhaps we could persuade councils or owners to let someone sow LOCAL, suitable and non-invasive native seeds or plants.
