here are a few reasons for the gold dots...
camouflage - they reflect colors of the surroundings and break up the shape of the chrysalis
warning - somehow the coloration would fend off predators
protection - they filter particular wavelengths of light which might be harmful to the monarchs
nothing - no function, but just the result of something else in the cuticle
the more i read, it seems to be, that they are points of entry for air entering the chrysalis.
whatever the reason for them... they look like 14kt gold and jade to me... just a beautiful jewel.
