Amphibians and many species of invertebrates go through a metamorphosis where they change dramatically in their different phases. However, there are some species of insects that go through an INCOMPLETE metamorphosis!
Let's take a look at what that means.
In their larval phase, animals often live in different habitats and eat different food than the adults, which helps them avoid competition!
For example, caterpillars live on plants and eat their leaves, while adults can move from plant to plant and drink nectar!
Some species are strategic about the time of year they lay eggs to start the metamorphosis process. Many short lived species will lay eggs in the spring when there are lots of resources for offspring.
Some other species, like the yucca moth, stay safe in their chrysalis during the cold winter.
Some insects can speed up or slow down the different phases of their metamorphosis depending on the climate.
Some moths and butterflies will remain in their pupas until spring when flowers start to bloom, while many insect eggs can hatch quicker when temperatures are warm.

Animals can look very different during the phases of metamorphosis!
Photos 1 through 4 show four animals during different phases of their metamorphosis. Using your best judgement, match each immature animal to its adult form!
B - Dragonfly!
Dragonfly nymphs do not have wings and live in water. Some dragonflies can stay in their nymph phase for up to four years!
D - Butterfly
The pupa, or chrysalis, shown in this photo will eventually produce a beautiful butterfly!
A - Ladybug!
Like butterflies, ladybugs will change from their larval phase to an adult while in a protective shell.
