The arrival of a small white moth in Nevada is sparking some big concerns among entomologists and foresters. "We are seeing 100-fold what we saw last year. Which means something has changed. Something is out of balance to allow them to flourish like this," says Gail Durham with the Nevada Division of Forestry.
White Satin Moths feast on Aspens, cottonwoods and willows. You can see the path of their destruction in the tops of the aspen groves at the Spooner Summit State Park. Within a quarter-mile of the turn off, the lower leaves of the trees are laden with larvae nesting and pupating. Just above the leaves in the tree tops are lacy and eaten.
