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.

How are flowers pollinated?
They get blown away by the wind, get carried from flower to flower by a bee or butterfly, and some flowers have female flowers and male flowers and they reproduce then when pollen gets stuck on to the pistil. I think flowers are pollinated because everything is a circle of life. For example, flowers and plants need bugs to help pollinate them or they will die. Bugs need pollen because without it they will die. If bugs were to no longer exist, then plants will no longer exist. If plants don't exist, we (humans) eventually will no longer exist as well.
