Nematomorph Parasites Manipulate Hosts Independently of Lunar Cycle

New research from Kyoto University indicates that nematomorphs, or horsehair worms, manipulate their nocturnal arthropod hosts to enter water at night, but this manipulation is not synchronized with the lunar cycle. This finding suggests that these parasites may employ alternative strategies for host manipulation that are less dependent on light conditions, such as altered geotaxis or increased locomotor activity.
