Assassin bugs (family Reduviidae) are highly skilled terrestrial ambush predators easily recognized by their narrow heads, and sturdy, curved beaks. While nymphs generally resemble adults in their leggy, elongated body shapes, they completely lack wings. Just like the adults, these nymphs are voracious carnivores; they inject paralyzing digestive enzymes into their prey before sucking out the liquefied bodily fluids. Because they feed heavily on agricultural pests like caterpillars, aphids, and beetles, they are highly beneficial to farmers and gardeners alike. However, they should always be admired from a distance—their defensive bite is notoriously painful! I discovered this striking 1.5-cm nymph while exploring Nanegalito, an Ecuadorian village located just a short bus ride from Quito.
