Distinguishing Feature : The white and black markings, being the only colours present.

A fairly common butterfly in the UK of mainly Wales and the South of England. Found in flowery grasslands of up to 2000m high. Like the Antler Moth, the Marbled White butterfly drops her eggs in flight, with the newly hatched caterpillars going straight into hibernation without first feeding.

The colouring white pigments in the Marbled White butterfly are made by flavins (which are related to the pteridine pigments) which the butterfly obtains directly from the leaves of Colt's-foot Grass (Dactylis glomerata) upon which its larvae feeds.
