Caterpillar eruption near Mount St. Helens
The Associated Press
Swarms of tent caterpillars have erupted in trees growing in the blast zone near Mount St. Helens.
The Forest Service says it's unclear why there are so many of the insects this year, but biologists consider it part of the natural process following the volcano's eruption 32 years ago, and they don't plan any controls.
The Daily News reports ( http://is.gd/i261pd) that if the caterpillars kill some alder trees that may help other species take hold. And once the caterpillars turn into moths, they'll be a food supply for bats.
