Investigators of wireworms early observed that elaterid beetles or click beetles, the adults of wireworms, have the habit of gathering under beet tops, slices of potato, piles of straw or other debris lying on the soil surface in open fields. The possible advantage that might be taken of this habit in trapping and collecting these beetles was called to the writers' attention by E. W. Gerry of Ventura, Calif., who in 1930 put out small piles of malva at the rate of one trap pile to the acre in a 12-acre bean field and collected nearly 7,000 beetles underneath these piles. In 1931 he collected over 9,000 beetles from the same field, although the trap piles were not put out until several weeks after the beetles had begun flying.
