Stylurus townesi

Stylurus townesi can be distinguished from other Stylurus species by specific morphological features, though detailed diagnostic characters are not readily available in the provided sources. The genus Stylurus contains multiple species with similar general appearances, requiring examination of specific abdominal patterning, thoracic markings, and male terminal appendages for definitive identification. It is distinguished from other Gomphidae genera by characteristics of the genus Stylurus, including features of the male genitalia and wing venation.

Rivers. The species is specifically associated with flowing water habitats, where the aquatic nymphal stages develop and adults patrol for prey and mates.

Endemic to the United States. Specific state-level distribution records are limited in available sources, but the species occurs within the North American range of the genus Stylurus.

As a predatory dragonfly, Stylurus townesi likely functions as both predator and prey within riverine food webs. Nymphs are aquatic predators feeding on smaller invertebrates, while adults are aerial predators capturing flying insects. The species contributes to nutrient cycling between aquatic and terrestrial ecosystems through emergence.
