Monarch butterflies’ ancestors migrated
The earliest monarch butterflies originated in North America and were migratory. Some of the insects later lost that ability as they moved into the tropics, a genetic analysis finds.

No Tickling: Common caterpillars deploy defensive hair
The caterpillars of the European cabbage butterfly have a chemical defense system that scientists haven't documented before.

New Green Eyes: First butterfly that’s genetically modified
Scientists have genetically engineered a butterfly for the first time, putting a jellyfish protein into a tropical African species so that its eyes fluoresce green.

Rethinking Refuges? Drifting pollen may bring earlier pest resistance to bioengineered crops
Pollen wafting from bioengineered corn to traditional varieties may be undermining the fight to keep pests from evolving resistance to pesticides.

Insects, pollen, seeds travel wildlife corridors
Strips of habitat boost insect movement, plant pollination, and seed dispersal among patches of the same ecosystem.

Bt Corn Risk to Monarchs Is ‘Negligible’
A much-anticipated report states that the most commonly planted forms of genetically engineered Bt corn pose only a "negligible" risk to monarch butterfly populations.
