Red Milkweed Beetles
These types of beetles are from the long-horned family. They have very long antennae that are placed quite close to their eyes. Red milkweed beetles are one of the few species of insects that can feed safely on milkweed.
Similar to Monarch butterflies, they store organisms from the milkweed that makes them very distasteful. A bird or other predator will almost always vomit after consuming one.
