Hawthorn White (Aporia crataegi) is a large butterfly with snow-white wings and distinctly veined wings. The veins are black in males, and dark brown in females. Its body is densely whitish, the legs are black. Also the antennae are black, only their club-shaped tip is white. Over time Hawthorn White butterflies lose the scales that cover their wings, so these can become almost completely transparent towards the end of the species' flight period. The veins remain dark, because they are not covered by scales.

Hawthorn White butterflies are found in a variety of habitats, usually between 500 and 2000 m above sea level. They especially prefer warm and sunny areas dotted with shrubs of host plants and various species of asters, where adult butterflies like to sip nectar. The caterpillars of Hawthorn White are often prey to parasitic wasps that lay eggs in them.
