Caenocholax fenyesi is a species of twisted-winged parasitic insects in the order Strepsiptera and family Myrmecolacidae.[2] It has a sporadic distribution throughout North America, Central America, and South America.[3] Chaenochlax brasiliensis (Oliveira and Kogan 1959) is the only other named species in the genus.[2]

C. fenyesi displays heterotrophic heteronomy, where males and females occupy different hosts.[4][3] Females are endoparasites throughout their lifecycle and parasitize members of Orthoptera, while larval stage males are endoparasites of Solenopsis invicta, the red imported fire ant, and are free-living as adults.[4][2] Males in Arizona, Mexico, Central America, and parts of South America have performed a host switch and parasitize native fire ants closely related to S. invicta.[2] They are highly virulent in their adult hosts, but not in their larval hosts due to a slower growth rate in larval stages.[5]
