The Marbled White is easily recognised, being of a good size, with a creamy (sometimes yellow-tinged) white ground colour with black vein markings and blotches between. Eyespots are present but tend to be disguised by the black blotches. The underside is similar but the markings are fainter, while the eye spots are particularly clearly marked on the under hindwings. The outer edges of the wings are scalloped with white with a further black scalloped border on the inside of the edging.
The adult Marbled White flies in mid-June, July and early August, and is single-brooded.
They nectar on a variety of meadow flowers, with a marked preference for purple flowers, such as Marjoram, Scabious, Thistles, and Knapweeds.
