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

open access: goldPLoS Biology, 2008
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.

Demystifying Monarch Butterfly Migration [PDF]

open access: yesCurrent Biology, 2018
Every fall, millions of North American monarch butterflies undergo a stunning long-distance migration to reach their overwintering grounds in Mexico. Migration allows the butterflies to escape freezing temperatures and dying host plants, and reduces infections with a virulent parasite.

History of colonisation and updated distribution of the Monarch butterfly Danaus plexippus (Linnaeus, 1758) and its hostplants in mainland Portugal, Azores and Madeira [PDF]

open access: yesNota Lepidopterologica, 2023
The first observations of the Monarch butterfly (Danaus plexippus) in Iberia date from 1886, although breeding records emerged almost a century later: 1960 in Spain, 1980s–1990s in Madeira and Azores, and 2003 in mainland Portugal.

Neurobiology of Monarch Butterfly Migration [PDF]

open access: yesAnnual Review of Entomology, 2016
Studies of the migration of the eastern North American monarch butterfly (Danaus plexippus) have revealed mechanisms behind its navigation. The main orientation mechanism uses a time-compensated sun compass during both the migration south and the remigration north.

Monarch butterfly population decline in North America: identifying the threatening processes [PDF]

open access: yesRoyal Society Open Science, 2017
The monarch butterfly (Danaus plexippus) population in North America has sharply declined over the last two decades. Despite rising concern over the monarch butterfly's status, no comprehensive study of the factors driving this decline has been conducted.
