Illustration of Small Milkweed Bug (Lygaeus kalmii)

The Small Milkweed Bug is a brightly red-and-black patterned seed bug that feeds on milkweed seeds and sequesters toxic cardiac glycosides, making it unpalatable to predators — its aposematic coloration serves as a warning. It overwinters as an adult and is commonly found in large aggregations on milkweed seed pods in summer. It is much smaller than the Large Milkweed Bug.
