Excerpt from Winter Comes and Goes: The How and Why Science Book A tiny moth laid an egg on this stem, Miss Adams told the children. The egg hatched into a caterpillar. The caterpillar went into the stern. It made the goldenrod stem grow big. See, the caterpillar lives inside. Bumps like this one are insect galls, Miss Adams said. If we had not cut into the gall, the caterpillar would have lived there all winter. Many plants have insect galls on them.
