Guides

• Eupathocera

  Eupathocera is a genus of twisted-wing parasites in the order Strepsiptera, family Xenidae. Currently considered a synonym of Paraxenos, species historically placed in this genus are obligate endoparasites of insects. As with other strepsipterans, they exhibit extreme sexual dimorphism and complex life cycles involving host manipulation.

• Eupathocera auripedis

  Eupathocera auripedis is a species of twisted-wing parasite in the order Strepsiptera, family Xenidae. As an obligate endoparasite, it infects host insects and completes its life cycle within their bodies. The species has been documented parasitizing the grass-carrying wasp Isodontia mexicana. Like other strepsipterans, it exhibits extreme sexual dimorphism and complex life history traits associated with its parasitic lifestyle.

• Eupathocera erynnidis

  Eupathocera erynnidis is a species of twisted-wing parasite in the family Xenidae. It is an obligate endoparasite of insects, with females remaining permanently within host abdomens while males develop to a free-flying adult stage. The species has been documented in North America, including Florida. Like other strepsipterans, it exhibits extreme sexual dimorphism and complex life history adaptations associated with parasitism.

• Eupathocera lugubris

  Eupathocera lugubris is a species of twisted-wing parasite (order Strepsiptera) in the family Xenidae. The species was originally described by Pierce in 1908 and is currently treated as a synonym of Paraxenos lugubris. Strepsipterans are obligate endoparasites of other insects, with this species likely parasitizing wasps or related hosts. The genus is part of the diverse and complex parasitic wasp-associated Strepsiptera fauna of North America.

• Eupathocera westwoodii

  Eupathocera westwoodii is a species of twisted-wing parasite in the order Strepsiptera. These insects are obligate endoparasites of other insects, with larvae entering hosts through joints or sutures. The species has been documented parasitizing wasps, including the Great Black Wasp (Sphex pensylvanicus). Females are neotenic and remain permanently within host abdomens, while males emerge as free-flying adults that live only a few hours and must mate within that brief window.

• Leionotoxenos tigridis

  Leionotoxenos tigridis is a species of twisted-wing parasitoid in the family Xenidae. The species was originally described as Pseudoxenos tigridis by Pierce in 1911 and later transferred to the genus Leionotoxenos. It is known from a small number of observations in North America, particularly from Illinois. As with all Strepsiptera, this species is an endoparasitoid of other insects.

• Xenos bicolor

  Xenos bicolor is a species of twisted-wing parasite in the family Xenidae, order Strepsiptera. Like other strepsipterans, it is an obligate endoparasite that develops within the bodies of host insects. The genus Xenos is known to parasitize wasps, particularly paper wasps in the family Vespidae. Strepsipterans exhibit extreme sexual dimorphism and reduced morphology, with neotenic females remaining permanently embedded in host abdomens.
