Habitat loss imperils monarch butterflies across the US Midwest

Researchers in a July 2011 study find significantly reduced populations of monarch butterflies across the US Midwest as milkweeds, where the butterflies lay eggs for their young, are being eliminated by herbicides as well as genetically modified corn and soybeans, leaving the butterflies flying over 100 million acres of farmland in search of the milkweed plants.
