In this outdoor activity, learners find the swollen bumps known as "galls" on various plants and get a closeup look at the parasitic animals living inside. Galls form on various plants including rosebushes, oaks, elms and willows after a female insect places one or more eggs into the living tissue of a branch or leaf. Learners explore what the galls provide, such as food or protection, as eggs become larvae, and what effects larvae have on their specific host plants.
