                                            Unlike many butterflies, the Silver-washed Fritillary lays its eggs not directly on the host plant<\/strong>, but in bark crevices near<\/strong> violets. The caterpillars then crawl to the food source in spring\u2014an unusual and clever strategy.<\/p>\n\n\n\n
