Roaches die belly up because their nervous system shuts down, causing their legs to curl up and their body to flip over. This is a common position for dead insects due to the way their muscles contract after death.
They curl up for protection, and use gnathpds to inject venom.
They are generally looking for damp environments and water. If they can't find it they will die......not to mention the bug spray they can pick up on their legs and then clean it off will kill them.
Stink bugs do end up going their legs back. This happens due to theoccurrence of elemental movement in their body's. When their legs grow back they also pick up more speed than they had before. A stink bugs speed rate can go up to 300 mph.
To properly use the leg curl machine, adjust the machine to your height, lie face down on the bench with your legs under the pad, and curl your legs up towards your buttocks using your hamstrings. Slowly lower the weight back down and repeat for the desired number of repetitions.
Woodlice form the suborder Oniscidea within the order Isopoda, with over 3,000 known species.

Creatures with exoskeletons frequently have a primitive muscle/blood flow circulation system tied into each other and it is hydraulic by nature. The natural state of their legs is curled up and a force of exertion combined with the pushing of blood through their legs causes them to straighten. They have fine motor control of this which allows them to move, in fact it's probably unconscious such as the way we move our limbs, the process is lsot on us we just know we can do it. Now, when the insect in question hasn't got enough food or water they grow weak, or with something like old age. So they find it harder to exert to force their legs "open" So imagine their standing on all their legs and can't summon the effort to keep the set on one side open. That side will collapse and they will tip. This causes them to roll over onto their backs. You can try this with a healthy insect and they will tilt and get back up but it's a strain and they use their legs a lot. When they are too weak to do this they are stuck, and frequently die shortly afterwards as they become too weak to right themselves.
Roaches often die upside down because their nervous system shuts down, causing their legs to curl up and making them unable to right themselves. This can happen due to various factors such as poisoning, dehydration, or old age.
Curl-up was created in 1951.
Koalas do smetimes curl up tightly when they sleep. They curl up in winter to keep warm.
Stick insects only look like sticks, if you look up close, you can see that they have legs. (6) They move by using their legs.
