What does a cockroach that molts look like?
Cockroaches molt before the nymph becomes an adult. That is, cockroaches molt the exoskeleton (exuviae) about 6 times. After each molt, cockroaches appear bright white and are especially vulnerable to injury until a hormone called brucicon darkens and hardens the exoskeleton.
What happens if a cockroach drops out?
Cockroaches cannot grow beyond the limits of their hard exoskeleton, so they must molt this hard skin to grow. Depending on the species, cockroaches molt 11 to 13 times to grow from nymphs to adults. After molting, the cockroach peels off the old skin and leaves it behind.
How do cockroaches behave when they are dying?
The long legs have a high center of gravity and carry most of the weight on the back. When a cockroach is dying at an old age, its high center of gravity pulls its back towards the floor, and its rounded back and weakened muscles prevent the cockroach from recovering, especially in a smooth condition.
