The Lygaeoidea are a sizeable superfamily of true bugs, containing seed bugs and allies, in the order Hemiptera. There are about 16 families and more than 4,600 described species in Lygaeoidea, found worldwide. Most feed on seeds or sap, but a few are predators.
The Lygaeidae are a family in the Hemiptera, with more than 110 genera in four subfamilies. The family is commonly referred to as seed bugs, and less commonly, milkweed bugs, or ground bugs. However, while many of the species feed on seeds, some feed on sap (mucivory) or seed pods, others are omnivores and a few, such as the wekiu bug, are carnivores that feed exclusively on insects. Insects in this family are distributed across the world. The family was vastly larger, but numerous former subfamilies have been removed and given independent family status, including the Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae and Rhyparochromidae, which together constituted well over half of the former family.
