The Reduviidae are a large cosmopolitan family of the order Hemiptera (true bugs). They can be perceived as slightly unusual, [citation needed] but they are very common among the Hemiptera because almost all are terrestrial ambush predators (most other predatory Hemiptera are aquatic). The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily.
