Studies on domesticated members of these so-called hairworms
have indicated that the life cycle of gordiids involves five different life stages: (1) egg strings, (2) free-living larvae, (3) parasitic cysts, (4) parasitic juveniles, and (5) dioecious or parthenogenetic free-living adults.
Scientists believe that hairworms produce substances that change the cricket's behavior.
Hairworms grow to maturity inside crickets' bodies.
Growth and development of the hairworm larva occurs after the paratenic host is consumed and the hairworm larva enters the body cavity of a developmental (or definitive) host, usually an insect predator or omnivore.
SYNOPSIS OF NORTH AMERICAN HAIRWORM SPECIES WITH GEOGRAPHIC LOCATION AND HOST RECORDS (IN ALPHABETICAL ORDER)
(1991) reported parasitism by this hairworm in the camel cricket, Ceuthophilus stygius and cave cricket, Hadenoecus subterraneus.
found in Scottish agricultural land, with descriptions of two new species of Gordionus Muller (Nematomorpha: Gordiidae).
persuade grasshoppers to drown themselves so that the worms can emerge and find a mate.
(1949) mentioned that "occasional hairworms
(Gordiaceae)" were collected during their biological survey of the Root River basin, a drainage system that includes Diamond and Gribben creeks.
Several lines of evidence suggest that pre-contact populations in the New World suffered from a variety of injurious parasites, including round worms, tapeworms, flukes, pinworms, hairworms
, hookworms, possibly trichinosis, and others (Reinhard 1990).
