description Stylurus plagiatus Overview

Stylurus plagiatus, commonly known as the russet-tipped clubtail, is a large species of clubtail dragonfly native to eastern North America. The insect was first officially described in 1854 and is characterized by its slender build and relatively wide abdominal tip. It primarily breeds in sizable rivers with muddy or sandy bottoms, relying on clean, flowing freshwater ecosystems. Observers can typically spot adults flying over open water or resting on sandy beaches during the late summer.

help Stylurus plagiatus FAQ

Where can I find Stylurus plagiatus dragonflies in North America?

Stylurus plagiatus is found across eastern North America, ranging from the southeastern United States northward into parts of the Midwest and along the Atlantic seaboard. The species breeds in sizable rivers with sandy or gravelly bottoms, so adults are most often encountered near appropriate riverine habitat during their summer flight season.

When was Stylurus plagiatus first scientifically described?

Stylurus plagiatus was described in 1854, placing it among the many North American odonate species cataloged by early entomologists during the mid-19th century. It belongs to the genus Stylurus, a group of clubtail dragonflies known for their association with large river systems.

What habitat does Stylurus plagiatus require for breeding?

Stylurus plagiatus breeds in sizable rivers with sandy bottoms, where its aquatic larvae develop in the substrate before emerging as adults. This habitat specificity means the species is vulnerable to river degradation, siltation, and changes in water quality that affect clean sandy riverbeds.

How can I identify a Stylurus plagiatus dragonfly in the field?

Stylurus plagiatus is a large clubtail dragonfly, identifiable by the club-like widening of the abdomen near its tip, which is characteristic of the Stylurus genus. Look for it patrolling over large sandy rivers during its flight season; close inspection of abdominal color patterns is typically needed to distinguish it from other Stylurus species in its range.
