A woman in Spain stumbled upon one strange creature in her courtyard.
Lujan Eroles, 46, spotted what may be an elephant hawk-moth caterpillar, a two-headed serpent-like animal.
Known for its propensity for feeding — honeysuckles and petunias are favorites — at night, it is often seen in urban settings. It typically has a metallic sheen with green and red flecks, and has excellent nighttime vision.
In this video, the freaky-looking caterpillar curls menacingly when prodded with a stick. Measuring about 4 inches long, its large eye blinks at the camera.
