Caterpillars and wasps

We seem to have had an invasion of butterflies recently particularly Large Whites and Small Whites and now they are munching their way through my nasturtiums which to be honest I sow to distract them from my vegetable plot, although the deer and voles have mainly eaten everything there apart from the courgettes, which Barrie says proves courgettes are inedible.
