Population explosion of caterpillars takes over Massachusetts

The state of Massachusetts is under siege by caterpillars. Scientists are trying to figure out what caused an apparent boom in the population of both native and introduced species of caterpillars.

The hungry larva are chomping away at the state's greenery. Species like the tent caterpillar and the gypsy moth caterpillar return in regular cycles, but the winter moth caterpillar is a new menace to the area.

Scientists say the winter moth has been in Nova Scotia for decades and is only now making its appearance in Massachusetts and Rhode Island. Other areas reporting outbreaks are Oregon and Washington state.
