assassin bug

Assassin bugs gain their sinister name from their habit of lying in ambush for their insect prey. With speed and precision, this bug injects its victim with a lethal toxin that dissolves tissue. Although many bugs use their sucking mouthparts for sipping plant juices, some have evolved as predators. When the food supply is limited, this insect will give up its ambush routine for a more active approach. http://www.insects.org/entophiles/hemi_009.html
