However, when they devil a humid, damp environment, they bring about sluggish and as semble in large numbers, often displaying a ! total want of locomotion. This is of course a taxis response sort of than a kinesis. I think that c all overs the gist of it. Experimental set-ups to licence this phototactic response are not that difficult to devise. The simplest involve placing a dozen or so woodlice on damp kitchen pass over in a high-walled petri dish or similar under normal room illumination.
