Silver-washed Fritillary ovum

 The female Silver-washed Fritillary normally lays her ovum [eggs] on the north facing side of a moss covered trunk of an Oak Tree, about 60cm of the ground. The larva emerge after 3 weeks and after eating the empty egg, immediately bury themselves deep down in a small hole/crevice in the Bark of the Tree and then spin a silk pad,  that they overwinter in. Emerging in the Spring.
