Cryptochromes define a novel circadian clock mechanism in monarch butterflies that may underlie sun compass navigation.

PLoS biology - 1 Jan 2008

Abstract excerpt

The circadian clock plays a vital role in monarch butterfly (Danaus plexippus) migration by providing the timing component of time-compensated sun compass orientation, a process that is important for successful navigation. We therefore evaluated the monarch clockwork by focusing on the functions of a Drosophila-like cryptochrome (cry), designated cry1, and a vertebrate-like cry, designated cry2, that are both...
