Students in Mrs. Williams's fourth-grade class were learning about different insects in Florida that undergo complete and incomplete metamorphosis.  Some insects look very similar, and some students were discussing two particular insects found in Florida. Using the chart, which explanation is correct?

• Martin said: Both the Luna Moth and the Rusty Millipede go through complete metamorphosis because they both look like caterpillars when they are young.

• Lizbeth said: Since both insects hatch from eggs, they both go through incomplete metamorphosis.

• Suzette said: The Luna Moth undergoes complete metamorphosis because the young and the adult look completely different.

• Harold said: There is no way to know because you cannot tell which type of metamorphosis an insect goes through by looking at the different stages of its life cycle.

The Giant Swallowtail Butterfly is native to Florida. The adults like to lay their eggs on citrus trees, which are abundant all over Florida. The larval stage of the Giant Swallowtail Butterfly eats the leaves of the citrus trees before they enter the pupal stage. This is why they earned the nickname Orange Dogs. The adult butterflies drink the nectar from other native flowers like Bougainvillea, Azaleas, and Milkweed.

How does the fact that the adults and the larvae eat different foods help ensure the survival of the Giant Swallowtail Butterfly?

• Having a different food source allows the adults and the larvae to eat the food they like.

• Having a different food source prevents the flowers from feeling left out.

• Having a different food source allows the adults to eat with their larvae.

• Having a different food source prevents the adults and larvae from competing for food.
