January Twenty-first
The wonderful changes just described take place throughout most of the insect world. The larvæ of butterflies and moths are caterpillars; the larvæ of June bugs or May beetles are grubs. Some moth and butterfly caterpillars weave silken cocoons about themselves; some make cocoons from leaves or tiny chips of wood; some utilize the hair from their own bodies, while others attach themselves to the under side of boards, stones, and stumps, where, after shedding their skin, they hang like mummies until spring calls them back to life.
