Spined assassin bug is an adept predator that patrols foliage in search of aphids, caterpillars, and various small insects. Using its rostrum, it injects a salivary concoction that immobilizes the prey and liquefies their internal matter. It's a nighttime hunter, increasingly active as dusk falls. Some specimens display a unique behavior by waving their forelegs, mimicking prey to lure inquisitive insects within striking distance.
