Early in 1918 reports began to come in to the Iowa Experiment Station of damage to bluegrass pastures by sod webworms. The first reports were from the extreme southwestern part of the state. These records were made either by correspondents, or by two field agents of the federal Bureau of Entomology at that time working under the writer's direction in the state.
