Explore Outdoors ~ Milkweed Bugs

 
 
Now I ask you: is this not a beautiful bug? And bug it is - a "true" bug, with sucking mouthparts and all. The large milkweed bug (Oncopeltus fasciatus) is marked with two black diamonds separated by a black band. It feeds exclusively on the sap and seeds of milkweed plants - sap that is toxic to most animals. But these bugs happily chug it down because it doesn't make them sick, and it confers upon them a certain advantage: animals won't eat them because of the bitter taste. Eat one milkweed bug and you won't eat another! You can read more about milkweed bugs on this post.
 
If you have milkweed growing near you, look closely. You might find a milkweed bug or two - and maybe some other milkweed visitors.

  1. What clever evolution to feed the bug what no one else wants!
