''Paragordius varius'', also known as the nematomorphs or horsehair worm, are known to control their definitive host to jump into a pool of water, thus allowing the adult worm to escape and reproduce.〔(【引用サイトリンク】url=http://animaldiversity.ummz.umich.edu/accounts/Paragordius_varius/ )〕 They are similar to nematodes but are much longer and very thin (>4 inches longer and 1/80 to 1/10 inch in diameter). ''P. varius'' is usually found in water or wet areas. These worms definitive host consist of grasshoppers, crickets, cockroaches, and some beetles.〔 == Physiology == ''P. varius'' have a slightly off-center mouth and distinct grooves running along its cylindrical body.
