Because when an arthropod sheds its skin, its new skin underneath is very soft, so the animal can grow once it's free of its hard armour. They're easy squishy prey during this period. They're only safe once the new skin hardens again.
Oh, not to mention the process itself often renders them immobile. Some (Spiders etc) have to lie on their backs for hours while taking off their 'panties'.

∙ 10y agoArthropods are more vulnerable to predators immediately after moulting because their new cuticle is soft; this process is necessary in order to undergo the actual shedding (ecdysis) itself and essential for growth since the exoskeleton is of sufficient hardness to make growth within it impractical. Right after shedding, the arthropod will usually expand in size (often owing to water intake) and hide for a while to mitigate the risk, until the new skeleton hardens.

Is the exoskeleton of the arthropod shed during molting?
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. :)
Why is molting necessary for arthropod growth?
Because of the composition of the exoskeleton. It must of necessity be tough to serve its function. Since it is inflexible, the organism has to periodically shed it (moult) in order to grow; a process called ecdysis.
Do arthropods have a live birth or lay eggs?
Lay eggs
How do arthropods give birth?
Arthropods include an incredibly diverse group of taxa such as insects, crustaceans, spiders, scorpions, and centipedes. There are far more species of arthropods than species in all other phyla combined, and the number of undescribed species in the largest assemblage of arthropods, the insects, probably numbers in the tens of millions. Members of the phylum have been responsible for the most devastating plagues and famines mankind has known. Yet other species of arthropods are essential for our existence, directly or indirectly providing us with food, clothing, medicines, and protection from harmful organisms.
What problems does an exoskeleton cause an arthropod?
I hope this helps (indirect problems) Exoskeleton usually don't cause arthropods problems except when they're growing. Arthropod are like snakes the must break out of their shell in order to grow bigger. When arthropods break out of their shell they must wait until the new skin hardens and becomes a shell again. During this time most arthropods vulnerable to prey due to the lack of protection from their shell Another problem would be the size of a crevice or hole when fleeing predators. If at the time of attack by a predator , the rigidity of the outer shell limits the size of the shelter to escape to.
What is the function of molting?
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.
Why is the time after molting dangerous for crustaceans?
Because they might get murked. And that is never good

When an arthropods molts it sheds its what?
Its exoskeleton, or 'armour'. A new one has already grown underneath it as molting begins, and only needs some time to harden out afterwards.
Why Is Molting Process a dangerous time for arthropods?

They're only safe once the new skin hardens again. Oh, not to mention the process itself often renders them immobile.

What does a penguin do when it is molting?
Replacing its feathers
What is the process of losing feathers from the body and wings called?
either molting or (and this is a joke. not for real.) DEATH! ha i really think its molting. a bird loses its feathers to grow new ones. it usually happens during winter to a bird that doesnt migrate and needs to be camoed. Hope it helped :)!
Do horses get tired during molting time?
No. This has nothing to do with a horses energy.
How long do laying hens moult?
The molting process can take several weeks to a few months to be complete. Molting tonic is available to help speed the process but just a bump up in feed amounts and the addition of fresh vegetables will help replace vitamins lost during this time. You will notice a drastic drop in egg production during the molt also, it too will recover when the molt ends.
What does an arthropod molt?
Yes, arthropods have to moult in order to increase in size, because their exoskeleton is rigid and inhibits growth. The process is called ecdysis and is not limited only to arthropods; it is a characteristic of their clade, ecdysozoa, which includes nematodes and other phyla. Arthropods are more vulnerable when moulting because their new exoskeleton is soft and therefore more vulnerable to predators. The new exoskeleton takes a while to harden; many will hide and wait during this time. Arthropods will usually moult multiple times during their lifespan; the process is also associated with lost limb regrowth.
Is it ok if your parakeet has feathers falling out all the time?
that just means their molting, its no big deal
Will appear 2-legs arthropods on earth in the future?
Arthropod evolutionary process. During the evolution of arthropods, the number of legs reduced. Definition of leg: The lower extremity of the animals that is in direct contact with the ground in standing or walking. A limb that used especially for supporting the body and for walking and crawling. Modified legs, is not leg. Mantis is 4-legged not 6-legged. 2-legs arthropods will appear on earth in the future. There are four-legged arthropods now. But all arthropods are not four-legged. Centipedes, spiders and insects there are still. There will be two-legged arthropods in the future and all arthropods will not be two-legged. But over time, their number will be increased gradually. 4-legged and 2-legged arthropods are not insects. They are new classes. Stronger blood circulation system is necessary to deliver blood to the head in stand upright. Ramin Amirmardafr
