Alydids

Alydids are a family of insects belonging to the order Hemiptera and the suborder Heteroptera. They are commonly known as broad-headed bugs or alydid bugs. This family is characterized by their relatively large, broad heads, which give them their common name. Alydids are found worldwide, with a significant diversity of species inhabiting various terrestrial environments, particularly in tropical and subtropical regions.

Adult alydids typically range in size from about 5 to 15 millimeters in length and exhibit a wide range of colors, often including brown, black, or cryptic patterns that aid in camouflage. Their mouthparts are adapted for piercing and sucking, and they primarily feed on the seeds and developing fruits of plants. Some species are considered agricultural pests due to their feeding habits, which can damage crops.

The life cycle of alydids involves incomplete metamorphosis, with eggs hatching into nymphs that resemble smaller, wingless adults. These nymphs molt several times before reaching adulthood. Many alydid species are known for their distinct odors, which they can release as a defense mechanism against predators. Some species are also gregarious, congregating in large numbers on host plants. The family Alydidae is part of the superfamily Coreoidea, which includes other families of true bugs.
