CARLSBAD CAVERNS NATIONAL PARK, N.M. (AP) - Moths, an important food for Carlsbad Caverns' famed bats, will be studied to find out what kinds of moths exist and how many there are at the park.
Eric Metzler, a butterfly and moth expert, has begun a planned 10-year inventory of moths at Carlsbad Caverns National Park.
He said he expects to find about 7,000 species of moths there.
