Wide open spaces, like much of Wyoming, are known to be strongholds for pollinators like butterflies. They often contain critical habitat and food resources, far away from the disturbance of human civilization. But it turns out even those areas are under threat.

The latest research, led by the University of Nevada, found a 1.6% annual reduction in the number of butterflies observed across more than 70 locations in the West over the past four decades. And it suggests warming during fall months in particular is driving the die-off.

New research shows that climate change and habitat loss are causing widespread decline among bumblebees in North America and Europe — and putting ecosystems that depend on these pollinators at risk.

Studies are revealing new, unintended threats that neonicotinoid pesticides pose to insects. The chemicals, widely used by farmers, are difficult to control because they persist in the environment.
