Alternatively, it happens when the butterfly is still a caterpillar. But the big picture stays the same. There are other limitations. You cannot stain individual tissues or proteins with coloured molecules, while still keeping the animal alive. And the scanners can only pick up a limited number of organs.
Brains and nerves, for example, are invisible to them, although Garwood hopes that new technological advances will overcome that hurdle. Micro-CT scans may not revolutionise what we know about metamorphosis but Garwood hopes that their advantages will give scientists new options for their experiments.
For example, the scans use up fewer individuals, since you can scan the same ones over time. This could free up insect specialists to move beyond the usual suspects like fruit flies, and study the development of rare or valuable species without harming them.
They could look at how pesticides affect the development of bees, or how mutations in different genes change the process of metamorphosis.

A butterfly chrysalis actually is the insect itself; it's not wrapped in silk or anything else. If you watch a caterpillar transform into a chrysalis, you'll see the caterpillar's skin split open and the "blob" that emerges from inside hardens into the chrysalis. It comes out of there chrysalis when it is spring. If you cut it open and dont go to a hospital you will bleed to death If you cut open your ballsack you will eventually start to bleed you won't have to worry about seeing your testicles though becasue there are couple layers of skin fat and muscle.

Another name for a chrysalis is a pupa. A chrysalis or nympha is the pupal stage of butterflies.

Butterflies and Moths. Study now. See Answer. Best Answer. Study guides. Q: What happens if you cut open a chrysalis? Write your answer Certain highly organized groups of cells known as imaginal discs survive the digestive process.
Before hatching, when a caterpillar is still developing inside its egg, it grows an imaginal disc for each of the adult body parts it will need as a mature butterfly or moth—discs for its eyes, for its wings, its legs and so on. In some species, these imaginal discs remain dormant throughout the caterpillar's life; in other species, the discs begin to take the shape of adult body parts even before the caterpillar forms a chrysalis or cocoon.
Some caterpillars walk around with tiny rudimentary wings tucked inside their bodies, though you would never know it by looking at them. Once a caterpillar has disintegrated all of its tissues except for the imaginal discs, those discs use the protein-rich soup all around them to fuel the rapid cell division required to form the wings, antennae, legs, eyes, genitals and all the other features of an adult butterfly or moth.
The imaginal disc for a fruit fly's wing, for example, might begin with only 50 cells and increase to more than 50, cells by the end of metamorphosis. Depending on the species, certain caterpillar muscles and sections of the nervous system are largely preserved in the adult butterfly. One study even suggests that moths remember what they learned in later stages of their lives as caterpillars. Getting a look at this metamorphosis as it happens is difficult; disturbing a caterpillar inside its cocoon or chrysalis risks botching the transformation.
But Michael Cook, who maintains a fantastic website about silkworms , has some incredible photos of a Tussah silkmoth Antheraea penyi that failed to spin a cocoon.
You can see the delicate, translucent jade wings, antennae and legs of a pupa that has not yet matured into an adult moth—a glimpse of what usually remains concealed.
