Why do dead cockroaches often back up to the sky

Sometimes we see some obnoxious cockroaches dying around the house, and they are always in the "exposed belly" position, right? So, why do dead cockroaches often tilt their bellies and raise their feet to the sky?

According to animal experts, cockroach body consists of 3 parts: head, chest and abdomen. They have 3 pairs of small and hairy legs to support that heavy body. In addition, the cockroach's legs have another important task is to help the cockroaches feel the surroundings.

Three pairs of cockroach legs are quite flexible, allowing the insects to wriggle for food and hide in very narrow crevices. However, when killed, cockroaches lose control of the muscles causing the leg muscles to contract. This makes it possible for cockroaches to lose focus and under the weight of their abdomen to fall backwards.

When cockroaches crawl on the wall and are exposed to insecticides, they immediately fall off the wall because the medication causes their leg muscles to contract, losing their ability to grip.

It can be said that dying in the supine position is an inherent property of cockroaches and is caused by muscle contraction. However, there are still cases of dead cockroaches lying face down rather than lying on the back, raising their feet to the sky.

In addition to the common feature of death, the cockroach has many other interesting features such as the body can continue to live without head for a few weeks, while the head can only exist for a few hours after being cut off. .
