In swallowtail caterpillars, the first three instars often resemble a bird dropping, while the last instars look much more like snakes.

Once more, the caterpillar eats, grows, and molts. This photograph shows a fifth instar caterpillar that is ready to pupate. This caterpillar has already spun a silk "girdle" which attaches it to the stem of the plant in a shape somewhat resembling a "c. Other species of butterflies have different positions for pupating. The fifth instar eats, grows, and becomes too big for its skin. This final caterpillar instar will molt one more time, but the result of this molt is quite different.
The chrysalis generically referred to as a pupa , is not a "resting" stage as many people think. Quite to the contrary, a lot is happening to the pupa! The body of the caterpillar is transforming into an adult butterfly! Wings are fully formed the beginnings of the wings were actually forming underneath the caterpillar's skin before its last molt in the chrysalis.
Antennae are formed and the chewing mouthparts of the caterpillar are transformed into the sucking mouthparts of the butterfly. After approximately 10 to 14 days as a chrysalis, the butterfly is ready to emerge. When the butterfly emerges from its chrysalis, its wings are small and wet, and the butterfly cannot yet fly. The butterfly must pump fluids from its abdomen through the veins in its wings, which causes the wings to expand to their full size.
Next, the wings must dry and the butterfly must exercise flight muscles before it can fly.
Papilio polytes …adult. The main job of an adult butterfly's life is to reproduce.

After a female butterfly mates, she searches for the proper host plant to lay her eggs, and the cycle begins again. Butterflies and moths go through the same stages in their metamorphosis with one difference.

Many moths form a cocoon instead of a chrysalis. Moths form cocoons by first spinning a silken "house" around them. Make sure to give www. Bees in Hive. Butterfly Eggs on a Leaf.

Growing Wings: The Power of Change
Others, like muscles, break down into clumps of cells that can be re-used, like a Lego sculpture decomposing into bricks. And some cells create imaginal discs—structures that produce adult body parts. It also only provides a snapshot in time. If you want to work out what happens as metamorphosis progresses, you need to cut open many pupae that you think are at different stages of development. But now, two teams of scientists have started to captured intimate series of images showing the same caterpillars metamorphosing inside their pupae.
Both teams used a technique called micro-CT, in which X-rays capture cross-sections of an object that can be combined into a three-dimensional virtual model. By dissecting these models rather than the actual insects, the teams could see the structures of specific organs, like the guts or breathing tubes.
How long does it take for a caterpillar to make a cocoon
They could also watch the organs change over time by repeatedly scanning the same chrysalis over many days. One team analysed the caterpillar of the stunning blue morpho just before it started metamorphosis and a week into the process. The second project had its origins in crime-fighting. This gets trickier once the flies turn into pupae, since those all look the same from the outside. But by scanning their insides using micro-CT, Simonsen hoped to get better estimates for how old they are. From flies, he turned his attention to his favourite subjects—butterflies and moths.
He worked with Tristan Rowe and Russell Garwood from the University of Manchester, who regularly scanned the cocoons of painted lady butterflies, some every day.
