Think you know monarch butterflies? Think again! A gardener’s observation has spurred a new study examining how and when monarchs feed on plants rich in compounds known as pyrrolizidine alkaloids. Surprisingly little is known about the behavior, and researchers are asking citizen scientists for help to learn more.
Tracking monarch butterfly movements by tagging them with tiny radio transmitters reveals flight patterns that may help researchers align habitat restoration with the natural behaviors of this iconic butterfly.
As human-driven changes to ecosystems drive insect declines on both local and perhaps global scales, entomologists and ecologists are hard at work building the research-based foundations necessary for managed insect-conservation efforts.
A study examining monarch butterflies' preferences for laying eggs on milkweed in cropland, open ground, or prairie—as well as predation rates on eggs in those settings—offers some mixed signals for monarch-conservation efforts.
Thanks to citizen volunteers, scientists now know more than ever about the flies that attack monarch butterfly caterpillars. Since 1999, volunteers participating in the Monarch Larva Monitoring Project have collected […]
