Yes. In most arthropods, molting occurs at the end of every juvenile phase to allow the individual to accumulate more mass and bigger size while still retaining the exoskeleton. Molting usually ends once the animal achieves adult size, such as with insects and many arachnids. In other arthropods, such as with crabs, lobsters and tarantulas, molting continues even in adulthood.
According to Biologists, arthropods must undergo a molting process where they shed their exoskeletons in order for them to grow.

Molting
Arthropods molt (moult) in a process called ecdysis. It is necessary for growth because of the inflexibility of the exoskeleton. The old shell remnants are called exuviae. Note that the term 'anthropod' should not be confused with 'arthropod'; anthropods are humans or humanoids and do not moult in the canonic sense.
Molting, or in Latin, ecdysis (meaning 'to strip'!).
Most only do so in larval/juvenile stages, when it's time to grow. Some arthropods such as tarantula females continue growing and molting until death. Also, when damage has occurred (torn off leg for example) molting can be induced earlier to develop and grow new appendages. :)
When arthropods outgrow their exoskeletons, they undergo periods of molting. During molting, an arthropod sheds its entire exoskeleton and manufactures a larger one to take the smaller ones place. Molting is controlled by the arthropods endocrine system. An animals endocrine system regulates body processes by means of chemicals called hormones. As the time of molting approaches skin glanes digest the old part of the exoskeleton and other glands secrete a new skeleton. Whenthe new skeleton is ready the animal pulls itself out of what remains of the original Skelton, this process can take several hours while the new exoskeleton is still soft the animal fills with air or fluids to allow room for growth before the next molting. Most arthropods molt several times between hatching in adulthood. This process is dangerous to the animal because it is vonerable to preditors while their shell is too soft to protect themselves. Most arthropods like to hide during molting or molt at night when less predictors can get them.
