Abstract

Traps baited with a sex attractant were used to determine if the invasive noctuid moth Hecatera dysodea (Denis & Schiffermüller, 1775) is generally distributed in the state of Idaho. The insect, which originated from Europe, utilizes species of Lactuca (lettuce) (Asteraceae) as a larval host. It was previously reported from northern Oregon and southern Washington but not the state of Idaho. The moth was subsequently captured in traps in six Idaho counties ranging from the south of the state near Utah to the north of the state in the panhandle area. A larva was also found on wild lettuce, Lactuca serriola L., near Boise, Idaho, and adults were captured in a light-trap near the southern border of the state. We conclude that the moth is generally distributed in the state at lower elevations where L. serriola is present.
