The navigation of the fall migration of the [[monarch butterfly|Eastern North American monarch butterfly]] (''Danaus plexippus'') to their overwintering grounds in central Mexico uses a time-compensated sun compass that depends upon a circadian clock in their antennae.<ref>{{primary source inline|date=November 2013}} {{cite journal | vauthors = Merlin C, Gegear RJ, Reppert SM | title = Antennal circadian clocks coordinate sun compass orientation in migratory monarch butterflies | journal = Science | volume = 325 | issue = 5948 | pages = 1700–1704 | date = September 2009 | pmid = 19779201 | pmc = 2754321 | doi = 10.1126/science.1176221 | bibcode = 2009Sci...325.1700M }}</ref><ref>{{primary source inline|date=November 2013}} {{cite journal | vauthors = Kyriacou CP | title = Physiology.
