Konza Prairie nature trail – Milkweed bugs (Oncopeltus fasciatus) taste lousy, part of their defense against predators. Instead of attempting to blend in with their environment they advertise their nastiness with a bright orange warning coloration. Massing together helps convey the message. I also notice the nymphs tend to hide under the adults (see photo below).
Great picture and wonderful nature lesson! I didn't know these things existed!
These guys look a little dangerous because of the colors 🙂
