"In rearing caterpillars and other leaf-eating larvK, branches of the food-plant should be stuck into bottles or cans which are filled with sand saturated with water. By keeping the sand wet the plants can be kept fresh longer than in water alone, and the danger of the larva; being drowned is avoided by the use of sand. "Many larva; when full-grown enter the ground to pass the pupal state; on this account a la}-er of loose soil should be kept in the bottom of a breeding-cage. This soil should not be allowed to become dr_\', neither should it be soaked with water. If the soil is too dry the pupa; will not mature, or if they do so the M'ings will not expand fully; if the soil is too damp the pupa; are liable to be drowned or to be killed by mold. " It is often necessary to keep pupa; over winter, for a large proportion of insects pass the winter in the pupal state. Hibernating pupa; may be left in the breeding- cages or removed and packed in moss in small boxes. Great care should be taken to keep moist the soil in the.
