(Needham, 1950)
Diminutive Clubtail

It inhabits specialized wetland environments including boggy trickles, slow small streams, and lakes with particular substrate requirements. The has been assessed as Least Concern by the IUCN, though it was previously considered rare or near threatened in earlier assessments. Known from approximately 18 across Georgia, North Carolina, and South Carolina, each with estimated stable populations around 1000 individuals.

Conservation history
The IUCN status of Phanogomphus diminutus has changed significantly over time: assessed as 'rare' (1986-1994), 'lower risk/near threatened' (1996), 'near threatened' (2007), and finally 'least concern' (2018 review). This progression reflects improved understanding of stability rather than recovery from decline.
Ant head attachment observation
A documented observation shows an individual with an clamped onto its profemur (front ), within reach of its . This parallels similar observations in tiger beetles and suggests complex -prey or defensive interactions with ants, though the exact circumstances remain unresolved.
