Honey bees are being hammered by some mysterious environmental plaque that has a name -- colony collapse disorder – but no established cause. A two-year study now provides evidence indicting one likely group of suspects: pesticides. It found “unprecedented levels” of mite-killing chemicals and crop pesticides in hives across the United States and parts of Canada.

Collagen gives the creatures a bug-catching advantage in chilly conditions.
