The cosmopolitan cutworm, Agrotis Ypsilon Rott., has occurred in destructive outbreaks on overflowed lands which have drained at a time favorable to oviposition by the moths. Such outbreaks have been recorded for the Gangetic Plain in India, the Wabash River Valley of Indiana, and the cranberry bogs of Massachusetts. A similar outbreak which destroyed a seeding of 200 acres of spring oats is here recorded for Western Oregon. The conditions leading up to this outbreak of June 1919 are described. Brief notes on the successful control of this outbreak by the standard bait method, the observed habits, natural enemies, fragmentary life history data, and a description of the larva, are included in this paper. It is concluded that similar outbreaks are likely to occur in future on lands overflowed in late spring in the Pacific Northwest.
