RENO, Nev. (AP) - Agriculture and forestry experts in Nevada, Utah and California are concerned about a potential infestation of a small white moth that can destroy entire groves of aspen, cottonwood and willow trees, especially in mountainous areas.
The white satin moth's numbers are up 100-fold this year in parts of Nevada, and no one is sure why.
The good news is experts from the three states who studied the moths near Lake Tahoe this month found signs their natural predators are making a rebound and should help keep the invaders in check.
Previous outbreaks were reported in Wyoming and Colorado, but the cousin of the gypsy moth flew largely under the radar in the Great Basin region until recently.
Nevada state entomologist Jeff Knight says it's now causing concern throughout the region.
