Assassin Bugs


With almost 7,000 described species, Reduviidae (Insecta: Heteroptera), or assassin bugs, are one of the largest and morphologically most diverse groups of Heteroptera, or true bugs (Froeschner and Kormilev 1989, Maldonado 1990, Cassis and Gross, 1995). Reduviidae have a worldwide distribution and are most diverse in the tropics of the Old and New Worlds. Assassin bugs range is size from only a few millimeters up to three centimeters long. They also show remarkable morphological diversity, with the so-called thread-legged bugs (Emesinae), kissing bugs (Triatominae), and ambush bugs (Phymatinae) being a few of only a handful of subfamilies that actually have a distinctive appearance in this heterogeneous taxon. Assassin bugs also show an exceptional range of specialization on their prey organisms. Sticky trap bugs (Harpactorinae), blood-feeding kissing bugs (Triatominae), ant-luring feather-legged bugs (Holoptilinae), spider web-inhabiting thread-legged bugs (Emesinae), and termite-feeding Salyavatinae are some examples of groups with apparently specialized feeding habits in this assemblage of more than twenty subfamily-level taxa. The most notorious Reduviidae are found among the kissing bugs or Triatominae, which are not only hematophagous on vertebrates, but also transmit Chagas Disease in humans.
