The assassin bugs, Reduviidae, are a large cosmopolitan family of the order Hemiptera (true bugs). They are slightly unusual overall, but very common among the Hemiptera (true bugs) because almost all are terrestrial ambush predators (most other predatory Hemiptera are aquatic). The main examples of non-predatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae.

Other common names for assassin bugs are wheel bugs and ambush bugs. Leaf-footed bugs look similar but are in a different bug family (Coreidae).

Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and formidable curved proboscis (sometimes called a rostrum). Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis.

There currently are 14 species documented in the park, but an estimated 60 species should be expected here.
