Rearing And Observing Them While Alive
While studying an insect it is advisable wherever possible to first study it where it is found in the field and later bring it home and keep it alive in a jar where it can be fed and observed and its various habits studied. Cages for breeding insects consist simply of a few glass fruit cans and jelly glasses with tin or cloth covers. A child can borrow one or two of these from his mother's fruit cellar. A layer of moist sand or soil should be put in the bottom of the jar to provide
a retreat for those forms which go into the ground before changing to adults. Before an insect is placed in one of these breeding cages its food plant should be determined by observations in the field, and every day or two a fresh supply should be gathered. Most of the forms discussed in the following chapters can be kept in jars and reared to the adult stage. Rearing insects is both interesting and instructive. Every child should be given an opportunity to rear a few forms either during the school year or during the summer vacation.
