Nearly all insects undergo great changes in form while getting their growth. Thus, caterpillars in time become butterflies or millers; grubs when fully developed are beetles; and maggots are the young of two-winged flies. In the case of butterflies, • millers, beetles, and t^o-winged flies, the fully developed insects bear but little resemblance in form to the young. It would be difficult to find two adult insects that differ more in form than do a butterfly and the caterpillar from which it was developed. But in the case of certain other insects, the changes undergone during the life of the insect are not nearly so great as with.
