Did you know that caterpillars of some butterflies and moths absorb nasty-tasting chemicals from plants to deter predators from eating them? Small white and large white butterflies lay their eggs on plants in the cabbage family and nasturtiums so they taste bitter. These are great bee-friendly plants too!
To find out more about the butterflies you can attract to your garden, see an article from a Wild Marlow steering group member and Butterfly Conservation volunteer Martin here: http://www.wildmarlow.org.uk/blog_page.php?bid=2
