Twice-stabbed Stink Bug Cosmopepla lintneriana

The name tells the story perfectly: two brilliant red spots at the rear end look like stab wounds, earning this stink bug its memorable moniker. Black with striking red, orange, or yellow bands across their backs, adults are impossible to miss. What's even cooler is watching their transformation: the nymphs range from white to red with bold black markings that shift and change as they grow, like living tie-dye shirts.

Widespread from Canada to Mexico, these bugs aren't picky eaters—they've been found on milk thistle, echinacea, asparagus, oats, mint, and goldenrod. Despite their fearsome name, they're just another member of the stink bug family, famous for releasing a foul odor when threatened. Those twin spots are nature's way of giving predators a fair warning.
