leaffoot

Leaffoot is a common name that can refer to several different types of insects, most notably certain species within the family Coreidae. These insects are also known as leaf-footed bugs or fern-footed bugs. The common name is derived from the distinctive flattened, leaf-like expansions found on the hind tibiae (the segment of the leg between the knee and the foot). These hind leg modifications are most pronounced in the adult stage and are thought to be used for display, possibly for mating purposes, or as a defense mechanism, perhaps by making the insect appear larger or more conspicuous.

Leaffoot bugs are true bugs belonging to the order Hemiptera. They are characterized by their piercing-sucking mouthparts, which they use to feed on plant sap. Their diet can include a variety of plants, making some species considered agricultural pests. They are found in various regions worldwide, often in warmer climates. The nymphs resemble the adults but lack the fully developed leaf-like expansions on their legs. Identification of specific species often relies on the shape and size of these leg expansions, as well as other morphological features.
