The
Lygaeidae are a family in the Hemiptera (true bugs), with some 60 genera in six subfamilies. The family includes the insects commonly known as
milkweed bugs, and also some of those known as
seed bugs. The family used to be vastly larger, as numerous former subfamilies have been removed and given independent family status, including Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae, Pachygronthidae, and Rhyparochromidae,
