Roly-poly bugs will move around in no particular direction until they find a suitable moist spot this kind of random movement in animals is known as what

Kinesis

Explanation:

Innate behaviours are behaviours that occur naturally in animals in response to external stimuli. These reflexes, taxis and kinesis.

Reflex actions are actions that occur involuntarily in response to external stimuli.

Kinesis is a non directional movement of organisms in response to external stimuli.

Taxis is a directional movement of organisms in response to external stimuli. It could be towards the stimuli or away from it.

In this case, the roly-poly bugs move aound in no direction until they find a suitable moist spot. This is certainly a kinesis.
