Since most roach species do not have wings, these appendages dont affect their ability to move. Have any problems using the site? However, when running upside-down, it needs stability, so the longer steps will slow it down. Often, an antenna will continue to react to stimuli even after it has been removed from a roach. The cockroach pushes off the ground with its feet and propels itself forwards. Researchers have used this device to study cockroach pheromones, or chemicals used to attract other roaches. It allows the roach to bend its leg to bring it forward, extend, and propel forward. This is one reason roaches can move out of the way very quickly if you try to catch or crush them.
