Can a cockroach regrow its legs?
Among the many praises that have been sung about the uniqueness of these insects, their ability to regrow their legs is one of them.
These insects are capable of regenerating their legs if they lose them.
Like many other insects, they possess the ability to regenerate their body parts. Adult roaches when they lose their legs undergo a molting cycle which enables them to regrow their limbs during this period.
The regrown legs of the cockroach may not be the same as the lost legs but it is active, viable, and performs its function.
The DNA of a cockroach is complex.
It makes their leg regeneration possible coupled with the fact that they possess a genome composition that sends network signals across their limbs, a signal that instructs nerves to regenerate limb tissues for these cockroaches.
These insects effectively regrow their legs because they have to evolve, survive, and adapt to a new environment. However, their regeneration does not include heads. Cockroaches may be able to grow their legs again but cannot regrow their heads.
Do cockroaches get rid of their legs purposefully?
A cockroach can willfully or purposefully lose its legs out of fear.

If this happens, know that the cockroach is scared at this point and will do anything to get to safety. A cockroach can also wilfully shed its legs if the particular leg is injured or broken.
In such a scenario where the cockroach has an injured leg, it will lose the injured part while the other part remains to make regeneration faster. Regeneration may take about five weeks.
How long does it take a cockroach to regrow legs?
There is no clear cut time assigned to the regeneration of a cockroach’s legs as the regeneration is dependent on the species of these insects, the number of lost legs, and the reason for the loss of legs;
It is dependent on these factors as every cockroach has a different regeneration pace. It may take a shorter time for some, and it may take longer for others.
That being said, the regrowth of a cockroach’s limbs may take about five weeks if the legs were taken off wilfully, by the cockroach. In a case where the legs were forcefully removed, it will take a longer time for the legs to regrow and the legs may not grow back to their full size. The regrown legs may be about 29% of their complete size.

Cockroaches can live without their legs and depending on the number of missing legs, can regrow their legs. They have the ability to live as long as other cockroaches whose legs are whole.
When a cockroach loses a leg or two, it undergoes the molting cycle and in the process regenerates new healthy, fast legs. So if you attempted to kill a cockroach and only succeeded in taking off its legs, the cockroach will survive and still grow new legs during its existence.
