Eric and an Inchworm

Sarah likes her worms, and so does her brother. We went to the botanical garden today, and Eric found an inchworm. He spent a long time admiring it and letting it inch around his hands. However, there is a noticable difference between what they do with the critters they find. Sooner or later, Eric finds some other interest, puts the bug down, and moves on. If she could, Sarah would name it, bring it home, make a home for it, and feed it. Remember Tenty, the tent catepillars?
