THE encouragement now being given to providing food plants for bees, butterflies and other insects is most welcome (Sussex Express, July 27).
However I consider that more emphasis should be given to the provision of food plants for caterpillars – no caterpillars, no butterflies. Unfortunately most species require wild flowers. Only a few like the so-called Cabbage White can feed on garden plants. So in addition to encouraging wild flowers in gardens could the people mowing verges on footpaths and roads please leave more food plants for the caterpillars.
