The following dialog is for questions 16 to 18. Randy Look at the butterfly! It's bigger than the others in this park. Kayla Are you sure it's a butterfly? Randy: I am. Kayla Well, it's not a butterfly. It's a moth. Randy: A moth? What's the difference? Kayla You see, those butterflies have colorful wings, but this one is brown. A moth has dull-colored wings that always open. Besides, it has a thick and fuzzy coat of scales on its wings. Randy: You're right. Butterflies have a thin and smooth coat of scales on their wings. Kayla Now, see the antennae. Unlike a butterfly's antennae which are long and thin, a moth has short and feathery antennae, used for smelling and flying. Randy I see. Thanks. 16.
