Since arthropods have a rigid exoskeleton, in order to grow they need to moult their entire skin, then wait for the new exoskeleton to harden. Some of them eat the old exoskeleton in order to recapture the mineral content. Since many (like the crustaceans) are vulnerable during this stage, they need to hide for a while. The moulting process for some arthropods also integrates with the limb regeneration function.
Ants do not change color with the seasons. At least more of the common ones don't Im not positive but there is no ant know to me that will change color. Ants have an exoskeliton. Meaing there skelital parts are on the outside of therre body, Unlike humens who have there bones on the inside. It would be extremly rare to find any living animal that can change the color of its bones
From the Related Link: "When we saw her sit and wait while the possum ate all her food, we took her in, she was between 8 and 12 weeks at that time. Fleas all over her. I bathed her with flea shampoo then kept her in warm cozy towels, watching her sleep, while she dried. The dang fleas were STILL THERE after she was dry. When we took her for her shots the next week, the vet gave me a spray bottle of some really noxious flea spray. She was too young to actually spray so we were instructed to spray a towel with the preparation and wrap her in it leaving only her face visible for I think 10 or 15 minutes. A few fleas tried to escape by running onto her face, I squashed them as they appeared. She didn't like the smell or confinement but when she felt the fleas disappearing she got comfortable and waited patiently! I combed all the dead ones out after I took the towel off."
Technically a caterpillar molts out of its cacoon after it has transformed to its butterfly form but a butterfly in adult form doesn't moot because they don't grow thick enough skin to moot in their small lifecycle
