Discussion questions

Talk about it

A female rice weevil drills a hole in a grain and lays one egg inside. The larva eats the grain from the inside as it grows, then transforms and emerges as an adult -- a whole life cycle inside one seed.

  1. Where does a young rice weevil grow up?
  2. What does the larva eat while it grows?
  3. What are the life-cycle stages before it becomes an adult?
