Read before answering

Life-cycle clue: the butterfly larva has finished its growth before its next transformation. Supplied simplified sequences: frog, egg -> tadpole -> young frog -> adult; butterfly, egg -> caterpillar -> pupa -> adult. Stages change in form, not only size. A pupa is not an egg. Insect life cycles vary: this butterfly sequence is not a claim about every insect. Do not collect eggs or disturb pond life.
