Aphid infestations reduce monarch butterfly colonization, herbivory, and growth on ornamental milkweed. [PDF]

open access: yesPLoS ONE, 2023
Anthropogenic disturbance is driving global biodiversity loss, including the monarch butterfly (Danaus plexippus), a dietary specialist of milkweed. In response, ornamental milkweed plantings are increasingly common in urbanized landscapes, and recent ...

Larval pesticide exposure impacts monarch butterfly performance. [PDF]

open access: yesSci Rep, 2020
AbstractThe long-term decline of monarch butterflies has been attributed to loss of their milkweed (Asclepias sp.) host-plants after the introduction of herbicide-tolerant crops. However, recent studies report pesticide residues on milkweed leaves that could act as a contributing factor when ingested as part of their larval diet.

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.

Stimulus-dependent orientation strategies in monarch butterflies [PDF]

open access: yesJournal of Experimental Biology, 2021
ABSTRACT Insects are well known for their ability to keep track of their heading direction based on a combination of skylight cues and visual landmarks. This allows them to navigate back to their nest, disperse throughout unfamiliar environments, as well as migrate over large distances between their breeding and non-breeding habitats.

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.
