Odontoloxozus longicornis
longhorn cactus fly
Odontoloxozus longicornis, commonly known as the longhorn cactus fly, is a species of true fly in the family Neriidae. This species exhibits complex reproductive behavior including male territoriality at oviposition sites and postcopulatory guarding. Males adopt condition-dependent mating strategies, with larger individuals defending territories on giant saguaro cacti while smaller males search for females. The species has been documented in desert environments of the southwestern United States and Mexico.
