Neil and his colleagues measured the acoustic qualities of fur found on the thoraxes and wing joints of moths and butterflies. Their analysis showed moth fur was thicker and denser than butterfly fur. In the lab, tests showed moth fur was better at absorbing ultrasonic waves.

The less a bat's acoustic signals echo off an object, the harder it is for a bat to recognize the object.

The USDA Animal and Plant Health Inspection Service created pink bollworm regulations in 1955, which were used in 10 states at the height of the program. States included Arizona, Arkansas, California, Louisiana, Mississippi, Missouri, New Mexico, Nevada, Oklahoma and Texas. The states were quarantined for the pest, but by 2003 only Arizona, California, New Mexico and Texas remained subject to the regulations.
