    Spined Assassin Bug - (Sinea diadema)

    A traveling hunter, the Spined Assassin Bug looks just as ferocious as its method for dispatching prey.


    Picture of Spined Assassin Bug
    Staff Writer (6/30/2017): Spined Assassin Bugs are covered in pointy spines or spikes. The purpose of them may be to fend off predators. The ones on front legs and the head may aid in subduing larger prey. Their presence gives the Spined Assassin bug a formidable appearance. The insect hides in plant foliage or on flowers, waiting for an insect to pass by it. The strong front legs grab the prey and a long fang at the mouth subsequently stabs the insect to death with rapid piercing movements. If handled carelessly, this fang can prick human skin creating a painful wound.

    Look for Spined Assassin Bugs in meadows, gardens and flower beds. They may be under leaves or inside blossoms.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
