Hemiptera is a large and diverse order of insects, commonly known as true bugs. They are characterized by their specialized mouthparts, which form a piercing-sucking proboscis. This proboscis is used to feed on plant sap, animal blood, or other body fluids. The order is divided into two suborders: Homoptera and Heteroptera. Homoptera, now often treated as a paraphyletic group within Hemiptera, includes insects like aphids, cicadas, leafhoppers, and scale insects, which typically have uniformly shaped wings. Heteroptera, the true bugs, exhibit more varied wing structures, with the forewings often being hardened at the base and membranous at the tips, forming a characteristic hemelytra. Examples of Heteroptera include stink bugs, shield bugs, assassin bugs, and water bugs.

Hemipterans are found worldwide in virtually all terrestrial and freshwater habitats. Their life cycles typically involve incomplete metamorphosis, with nymphs resembling smaller versions of the adults. They play significant ecological roles, acting as herbivores, predators, and vectors of plant diseases. Some species are considered agricultural pests due to their damage to crops, while others are beneficial as predators of pest insects or as sources of valuable products like lac. The diversity in size, appearance, and lifestyle within Hemiptera makes them a fascinating subject for entomological study.
