Description

The western bean cutworm, Richia albicosta (Lepidoptera: Noctuidae) is native to North America. It was first reported as a pest of Colorado pinto beans in 1915 and later, in 1954, it was identified as pest of corn in southern Idaho. Since its discovery in the late 1800's, it has slowly and steadily expanded its known distribution eastward from Arizona to southern Minnesota and central Iowa. The western bean cutworm was known to occasionally occur in western Iowa prior to 1970, but it was not until 2000 that an economically damaging population was found in field corn. Since then, it has become a recurring economic pest in western and central Iowa. In 2004, western bean cutworms were first collected in Illinois and Missouri.
