Coreinae

Coreinae is a subfamily of true bugs belonging to the family Coreidae. This family is commonly known as leaf-footed bugs or squash bugs due to their distinctive leaf-like expansions on their hind legs, although not all species within Coreinae exhibit this characteristic. Coreinae are distributed worldwide, with a particular diversity found in tropical and subtropical regions. They are herbivorous insects, feeding primarily on plant sap from various host plants, including many agricultural crops.

The morphology of Coreinae is varied, but many members share common features such as a relatively elongated body, prominent antennae, and often brightly colored or patterned forewings (hemelytra). The enlarged hind tibiae are a notable feature, though their size and shape can differ significantly between species and sexes. These hind leg expansions are thought to play roles in mate recognition, defense, or possibly in aiding movement. Life cycles typically involve incomplete metamorphosis, with eggs hatching into nymphs that undergo several molts before reaching adulthood.

While some species of Coreinae are considered agricultural pests due to their feeding habits, causing damage to fruits, vegetables, and other crops, many others are ecologically important as herbivores and food sources for other animals. Research on Coreinae continues to explore their taxonomy, evolutionary relationships, feeding ecology, and interactions with host plants. The subfamily encompasses a large number of genera and species, making it a significant group within the order Hemiptera.
