This one sure has difficulty trying to hide in the near dark National Butterfly Center grass. Those bold, bright red stripes blare out at you. Makes you wonder why this rare butterfly, that occasionally visits there, wonder why it has those red stripes.

When it did finally fly, it flew down the trail, some nearly 150 feet, always in sight and it followed a straight-line path, some 4 feet above the ground. I watched, transfixed, for I saw something that intrigued me. During that straight-line flight, those red stripes were always visible, they actually were always easily seen.

My hypothesis? This butterfly must be toxic to predators that would prey on it. Those red stripes may signal habitat predators that this butterfly is toxic (poisonous), and should not be captured.

Do you concur with this opinion?
