Previous to the present year noctuid moths were collected for breeding purposes and flight records, in various ways, entailing long hours spent in the field at night. The methods employed were variations of the old practice of “sugaring” and collecting from bloom. Fairly good results were obtained by systematic night collections, but it seemed desirable to devise a method whereby material might be secured in sufiicient quantities without so much night work. During the past winter the trap under discussion was designed and constructed as an experiment towards simplifying moth collections and flight records.
