In a test at St. John's from 20 August to 9 September 1964, grooved-board traps captured more specimens of the Eluropean earwig, Forficula auricularia L., than pitfall traps containing attractants. On 19 August two replicates of one grooved-board and eight Legner traps (Fig. 1) containing bran flakes plus an attractant were set up on a city lot. The Legner traps were set in the soil so that their tops were level with the surface. They were protected from rain by a 12 in. × 12 in. board held in position over the opening by short legs at the four corners. The attractants used were: peanut butter, cod oil, sugar, molasses, honey and macerated earwigs. The traps were attended from 21 August to 9 September and all earwigs removed daily and counted in the laboratory.
