Milkweed Longhorn Beetle (Tetraopes femoratus) Feeding on a Milkweed Pod

Macro, Dusk, September, Colorado

 

Milkweed beetles are commonly found in Colorado and live on and eat milkweed plants. Their red coloring is attributed to the alkaloid toxins they consume from milkweed. They are known to make purring and squeaking sounds. (I've not yet heard them do it!)
