7703 cutworms were collected in traps at Waltham between April 27 and July 17, 1927. Chickweed sods were used as traps in the largest experiment where 6627 cutworms were collected but shallow trays with a screen bottom when baited with chickweed proved to be as effective and were more easily handled. The cutworms in Group 3 which included Euxoa ochrogaster, Euxoa tessellata , and Euxoa perpolita comprised 94.34% of the larvae collected. Agrotis fennica and Agrotis unicolor were trapped in noticeable numbers. Rain and general cold cloudy weather noticeably decreased the numbers of cutworms collected while temperature variations had a less noticeable influence.
