Currently, the midland clubtail has only been identified twice in Sussex County, near a large river with sand and mud substrates.


Nymphs eat a wide variety of aquatic insects; adults feed on flying insects.


Little is known about the flight season of the midland clubtail in New Jersey; however previous encounters have been in June.


Due to its rarity in New Jersey (it has only been seen twice), the midland clubtail is considered a species of Special Concern.
