Flight-induced compass representation in the monarch butterfly heading network

Current Biology, 2021
For navigation, animals use a robust internal compass. Compass navigation is crucial for long-distance migrating animals like monarch butterflies, which use the sun to navigate over 4,000 km to their overwintering sites every fall. Sun-compass neurons of

Palatability dynamics of cardenolides in the monarch butterfly [PDF]

open access: possibleNature, 1974
THE adaptive strategy of sequestering cardiac glycosides from milkweed plants (Asclepiadaceae and Apocynaceae) has evolved in several taxa of insects1. Since these cardenolides elicit vomiting following ingestion, birds learn to avoid the insects on sight after one or more emetic experiences2.

Monarch Butterfly (Danaus plexippus) Life‐Stage Risks from Foliar and Seed‐Treatment Insecticides

Environmental Toxicology and Chemistry, 2021
Conservation of North America's eastern monarch butterfly (Danaus plexippus) population would require establishment of milkweed (Asclepias spp.) and nectar plants in the agricultural landscapes of the north central United States.

The case of the monarch butterfly: a verdict is returned [PDF]

open access: possibleTrends in Genetics, 2002
A publication reporting the harmful effects on the monarch butterfly of maize genetically modified to express insecticidal delta-endotoxins from the soil bacterium Bacillus thuringiensis (Bt) caused much public interest. A series of ecologically based studies were subsequently carried out to evaluate rigorously the impact of pollen from such crops and ...

Bioinspired Clustering in UWSNs Using Monarch Butterfly Optimization Compared with Ant Colony Optimization Algorithm

2024 IEEE International Conference on Communication, Computing and Signal Processing (IICCCS)
The Monarch Butterfly Optimization (MBO) algorithm for clustering in Underwater Wireless Sensor Networks (UWSNs) is investigated and compared to the performance of the Ant Colony Optimization (ACO) algorithm in this paper. As is evident from the outcomes

mSAIL: milligram-scale multi-modal sensor platform for monarch butterfly migration tracking

ACM/IEEE International Conference on Mobile Computing and Networking, 2021
Each fall, millions of monarch butterflies across the northern US and Canada migrate up to 4,000 km to overwinter in the exact same cluster of mountain peaks in central Mexico.

Inbreeding depression in monarch butterflies

Journal of Insect Conservation, 2016
Monarch butterflies and their unique system of multigenerational migration have long fascinated the public, and concerns for the fate of this charismatic insect have grown due to the consistent declines in overwintering colony size over the last 20 years.
