There are a number of possibilities:
The name may have, originally, only applied to "creatures" of a yellowish or butter coloured nature.
There was an earlier belief that butterflies ate milk and butter - German molkendiep ("butterfly", lit. "milk-thief");
Or that they excreted a butter like substance - Dutch boterschijte ("butterfly", lit. "butter-shitter")

Insects such as butterflies do not have skin, they have shells, technically chitinous exoskeletons, made of protein.
Probably! :) :(
Of sorts, they have what's called an exoskeleton, and it's made of sugars and proteins, not the same stuff that makes shells such as egg shells or the shells of molluscs.
There is only one situation when a butterfly has a coiled shell. This is when the butterfly has died and its internals are dried up. The shell then covers the dead insides.
I believe the shells are made of chitin.
Most car shells are made from pressed steel, some are made from plastics.
Shells are grown by shellfish to cover their insides.
it's made of a certain amont of bug shells and hard plastic
NO . Turtles shells are natural and grow with the turtle. Plastic is man made .
To determine if shotgun shells are made of steel or lead, you can use a magnet. Steel shotgun shells will be attracted to the magnet, while lead shotgun shells will not.
Shells .......
