Sunken and perforated cappings are sometimes observed just as in American foul brood (Fig. 163, c, g, j). The earliest indication of the disease is a slight yellow or gray discoloration and uneasy movement of the larva in the cell. The larva loses its well-rounded, opaque appearance and becomes slightly translucent, so that the tracheae may become prominent (Fig. 167, b), giving the larvae a clearly segmented appearance. The larva is usually flattened against the base of the cell but may turn so that the ends of the larva are to the rear of the cell (Fig. 167, p) or 2d.
