The banner clubtail exists in a disjunct population in New Jersey’s coastal plain in clean, acidic streams with sandy substrate and organic debris. The full range of the species is from Virginia to Louisiana and west to Texas.


Nymphs feed on aquatic invertebrates; adults on flying insects.


Banner clubtails are one of the first to emerge in the spring and are active from late April through mid July.


Due to limited habitat and rarity in New Jersey, the banner clubtail is considered a Threatened species.
