Swamp Milkweed Leaf Beetles can be found in marshes, bogs, swamps, and other wet habitats. It is thought the beetle and its early instars derive a measure of protection from predators by incorporating toxins from the plant into their cell structures, thereby becoming distasteful, similar behaviour to the Monarch butterfly … It is a close relative of, and a bit shorter than, the dogbane beetle, and it is Familiar family members are the Colorado Potato, the Cucumber, the Asparagus … They are not harmed by the toxin, but predators that feed on them are (a few tropical birds and rodents are able to eat Monarchs without harm—Mother Nature is always stirring the pot).

They damage the plants by chewing on the foliage, causing holes in the leaves. Its rubbery sap contains cardiac glycosides that, at the very least, make its imbibers throw up—unless they have, like the other milkweed grazers and a variety of herbivores that successfully feed on toxic plants, developed an adaptation that allows them to deal with the chemicals.
