Reduviidae, commonly known as assassin bugs, are predatory insects found in diverse environments worldwide, from forests to deserts. They exhibit a distinctive elongated head and a curved proboscis used for piercing prey. Notably, they play a crucial role in pest control, preying on various insects, including agricultural pests.

Reduviidae, commonly known as assassin bugs, are found worldwide, with a significant presence in tropical and subtropical regions. They are distributed across various continents, including North and South America, Africa, Asia, Europe, and Australia. Specific countries with notable diversity of Reduviidae include Brazil, Mexico, India, and parts of Southeast Asia.

Reduviidae inhabit a wide range of environmental conditions, from rainforests and woodlands to grasslands and deserts. They are often found in areas with abundant vegetation, which provides hiding spots and hunting grounds. Some species are adapted to more arid climates, while others thrive in humid, densely vegetated environments.

Assassin bugs are primarily predatory, occupying a niche as insect hunters. They are adept at ambushing or actively pursuing prey, which includes other insects and small arthropods. Their ecological role involves regulating insect populations and maintaining balance within their ecosystems. Some species are known to have specialized adaptations for hunting specific prey or surviving in particular microhabitats, such as under bark or within leaf litter.
