Neoconocephalus palustris
marsh conehead
Neoconocephalus palustris, commonly known as the marsh conehead, is a large katydid species in the family Tettigoniidae. It belongs to the conehead group, characterized by a distinctive forward-projecting cone on the head. The species is found in wetland habitats across eastern North America. Like other members of the genus Neoconocephalus, it is among the largest katydids in its range, with some individuals exceeding seven centimeters in length.
Neoconocephalus retusus
Round-tipped Conehead
Neoconocephalus retusus, commonly known as the round-tipped conehead, is a species of katydid in the family Tettigoniidae. Adults range from 37 to 52 mm in length and are active during late summer and autumn. The species is found in the eastern United States and southern Canada, typically in wet grassy and weedy habitats.
Ormia lineifrons
Ormia lineifrons is a multivoltine koinobiont endoparasitoid fly in the family Tachinidae. It is native to the Americas and has been studied extensively in Kentucky, USA, where it parasitizes four species of Neoconocephalus katydids in a sequential pattern across its three annual generations. The fly locates hosts by eavesdropping on male katydid mating calls, depositing first-instar larvae that develop internally and kill the host upon emergence. Its multi-species host use creates complex evolutionary dynamics with each host species exerting different selective pressures.
