These are Milkweed Bugs. What's the plant they're sitting on? It's a Milkweed plant. I really like the picture below. My mom likes it too. Those fluffy things in front, they're Milkweed seeds. Why is the plant called a Milkweed? Well, it has a liquid that looks like milk, but this is poisonous. It's also how the Monarch butterfly makes itself taste bad.
Today was really windy, so the Milkweed Bugs were all piled up. (That's what they do when it's really cold.)
