Be. Because most animals have a protective or skeletal arrangement on the back, and more fragile tissues such as muscles on the ventral surface, they are heavy on the back and light on the belly. Animals are mostly most vulnerable before they die, so the muscles are weak to support the heavier dorsal tissues, and the back falls to the ground due to gravity before death.

Some animals accidentally land on their backs, and their muscles are not strong enough to roll over, and they will die after a long time. In fact, not only cockroaches, but also fish, birds, and other beetles, most of them are facing down when they die, of course, it is not absolute, and some will also have their abdomen downward due to the terrain or special actions before death, but it is just rare.

Cockroaches rolling over don't necessarily die. Cockroaches because of their hard backs and lighter abdomen, because the center of gravity is on the back, it is not easy for cockroaches to turn over after turning over and then turning over to do side sensitivity, so it leads to waiting for starvation in one place, but it will slide when it struggles, and if there is a slope, it is still possible to turn over, so it may not die.
With the exception of cockroaches, most of the bodies are flat and have thick shells, as are insects with their center of gravity on their backs, and once they turn over, gravity shifts downward, making it difficult for Kaishan to turn over again, resulting in starvation or sunburn in the heat.
In most cases, cockroaches are due to dying, with straight legs and unsteady standing leading to turning over, so most of them will die after turning over and struggling for a while, but some are turning over for other reasons, and they will not necessarily die.

1. Since the cockroach stomata are in the abdomen, they usually rely on the "abdominal stomata to breathe", and before dying, it is like a person who will struggle when he is drowning, just to let the nose breathe more air. After the cockroach is applied to the insecticide, the source insecticide affects the nervous system of the cockroach and causes muscle spasms, and the cockroach breathes on the abdomen, and the back is down to help the cockroach breathe. The cockroach that flips over its body is unable to flip back into its body due to the deepening of the poisonous effect of the insecticide, and the cockroach eventually dies in a back-down position.
2. Before the cockroach dies, the motor nerve will be out of balance, shaking, tilting and struggling, coupled with the heavy back and light abdomen, it is easy to lose the center of gravity, showing six feet to the sky, that is, the phenomenon of belly turning.
3. Of course, in the wild, it is not common for cockroaches to die with their backs down. Cockroaches can easily turn their bodies over again in the wild because there are substances such as leaves, branches, and dust on the ground to make it easier for them to turn over.

Due to death. Cockroaches belong to insects, and almost most of them are six-legged after death, because the cockroach struggles desperately before it dies. It refers to natural death (trampling it to death or will not turn over), natural death of insects and drug poisoning, when the insect earns the liquid and tells Wuzha, its balance system is also ineffective, the winged friend finger is the opposite of the action of normal flight, flies, mosquitoes and other poisoning, being knocked down by electric swatters, poisoning are the same as cockroaches.

No. Cockroaches have a stiff and heavy back, a fragile and lighter abdomen, and a heavy back and a light belly structure that places its center of gravity on the back. When the cockroach rolls over, the center of gravity moves downward, close to the ground, and the center of gravity cannot be moved up without the influence of external forces. <

Cockroaches are insects that can adapt to a variety of environments and foods, and generally live in warm and humid environments, making them difficult pests to be eliminated. Not only that, cockroaches are also very capable of turning over, they can turn over on their own after falling, and in the process of turning over, they will also make special noises, attracting the attention of other people of the same kind.
Cockroaches' body structure gives them excellent ability to flip their babies. On their backs, in particular, there is a long midline that connects the left and right segments, which are long enough for cockroaches to make complex movements in a coordinated manner. When the cockroach falls, it will use the double vertical flip method, which usually only takes a few seconds to successfully turn back.
The cockroach's ability to roll over on its own is not only a reflection of its biological characteristics, but also a manifestation of its adaptability. In the wild, cockroaches will inevitably encounter various dangers, such as being attacked by other insects or being caught by humans. If you can't turn over, you'll be exposed to danger, which can have even more serious consequences.
In short, cockroaches can turn back on their own after turning over, because their body structure and movement methods have special age-appropriate fighting and self-protection mechanisms. This biological characteristic makes cockroaches a vigorous and difficult pest to eliminate, and we need to strengthen control in human health care to avoid further adverse effects on humans.
Yes. Cockroaches are tenacious, and after the male and female cockroaches mate, the tail end of the female cockroach grows a pod-shaped thing, that is, the egg sheath, in which the cockroach eggs are laid. A female worm can lay more than 10 eggs and more than 90 egg sheaths. In an egg sheath, 10 can be hatched, more than 50 small cockroaches can be hatched, after the death of the cockroach mother, the cockroach eggs will still reproduce, so it is often not recommended to step on the dead cockroach. >>>More
Summary: Causes of cockroaches:
1. Cockroaches can crawl directly to the home through the sewer or other pipes connected to the outside world, and can also climb in directly through the doors and windows of the home. >>>More
Cockroaches can be trampled to death.
But try not to step on it, Oriental Hanno exterminates cockroaches, because it may make cockroaches "step on more and more, cockroaches are also divided into male and female, and it doesn't matter if we step on male cockroaches to death." >>>More
Cockroaches are not hermaphrodites, because after male and female cockroaches mate, the tail end of the female cockroach grows a pod-shaped thing called an egg. >>>More
Because even if the cockroach dies, it can still "give birth". Let's say you see a cockroach at home and "biaji" squash it. Cockroaches are dead, but there is a good chance that the eggs in their bodies will splash out and fall elsewhere. >>>More
