About

The Large Milkweed Bug is a conspicuously orange-and-black true bug that sequesters toxic cardenolides from milkweed seeds, making it unpalatable to most predators. It has been a laboratory staple for decades — NASA even flew specimens aboard the Space Shuttle to study insect development in microgravity.
