Just freshly molted, I agree with Longhorn ^^ they are soft and squishy so unless you are feeding them off at that stage I avoid touching them because you can easily injure them.
Freshly molted, but looks pretty cool! I guess to distinguish them, you can look at the edges, and if they are sort of translucent, it is freshly molted. But if it is albino, it would just be white, because that is the pigment color, not freshly molted exoskeleton. There is not really a rule that I know of, just a sort-of theory, I guess.
There are lighter colored dubia now that have been line bred from an original batch which are called golden dubia. However when looking at the original posting it's not line breeding, it's pure inbreeding.
