The black-shouldered spinylegs is a large aptly named Clubtail. Their front thoracic stripes are bold and mostly fused together, making them appear to have a black shoulder, and they have long legs with numerous spines of varying length.
Black-shouldered Spinylegs males perch on leaves, rocks or the ground typically facing the water or patrol their territory, flying back and forth and occasionally stopping to hover. Females typically perch on shaded foliage in nearby woodlands. Black-shoulder Spinylegs can often be seen later in the summer than most other clubtails other than Stylurus
Small to large woodland rivers and streams and large lakes with rocky shoreline
Mating takes longer than other species and usually happens in the treetops. Females lay eggs by rapidly skimming the water and tapping their abdomen on the surface at regular intervals of a few feet.
