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.
