Swamp Milkweed Leaf Beetle (Family Chrysomelidae)
Members of the leaf beetle family Chrysomelidae (more than 1,700 species north of Mexico) are often named after the plants they specialize on. The Swamp Milkweed Leaf Beetles prefer Swamp milkweed, but they’re found on other milkweeds as well. Multiple eggs are laid under milkweed leaves; multiple larvae hatch out and feed together on milkweed leaves for a while before going their separate ways. Adults also feed on milkweed, enjoying both the leaves and the flowers.
