Lives hidden under plants, litter or plant debris. Can easily be mistaken as a piece of dead wood when it rests on its side, motionless on the bottom. Often swims on one side in undulating movements (Ref. 35381). Feeds mainly on terrestrial insects, particularly ants (Ref. 7462). Nocturnal (Ref. 6868). Vari, R.P. and H.
