Zelus tetracanthus
four-spurred assassin bug, sundew assassin bug
Zelus tetracanthus, commonly known as the four-spurred assassin bug, is a predatory true bug in the family Reduviidae. Adults measure 10–16 mm in body length and are recognized by a distinctive row of four spurs across the thorax. The species employs a unique prey-capture strategy using sticky secretions from specialized leg glands rather than muscular grasping. Both adults and nymphs produce these adhesive substances to immobilize prey. The species has been evaluated as a potential biological control agent for saltcedar leaf beetles (Diorhabda spp.) in tamarisk management systems.
