Fly may be depleting U.S. giant silk moths
A parasitic fly introduced to fight gypsy moths starting in 1906 may be an overlooked factor in the declines of giant silk moths.

Learning to Listen
Disparate groups of creatures, including bats, toothed whales, and birds, have evolved biological sonar that they use to track prey, but other creatures have evolved ways to detect this sonar and thereby increase their odds of survival.

How the Butterfly Gets Its Spots
The spots on a butterfly wing turn out to be unusually good model systems for a range of disciplines from genetics to behavioral ecology, offering biologists a chance to paint the really big picture of how evolution works.

Remnants of the Past
Sophisticated analyses suggest that some prehistoric peoples were highly skilled weavers.

Bioengineered crops have mixed eco effects
An unusually large test of the ecological impact of genetically modified crops finds mixed results, depending on the crop.
