LIFE HISTORY AND HABITS. METHODS OF STUDY. In studying the life history of the dock false-worm, rearings were made in an outdoor insectary with a roof but no sides. In order to rear the larvae under conditions as nearly normal as possible, they were kept on living plants. Small plants of the common curly dock (Rumex crispus) and of the wild buckwheat {Polygonum convolvulus) were potted in tin cans. After being
