Can you tell me what this one is…
Found on an orange tree in Friendswood , Texas . It rears aggressively when touched.
The Caterpillar of the Giant Swallowtail is known as the Orange Dog because of its favorite food source. Those orange horns are revealed when the caterpillar is disturbed allowing it to emit a foul odor, a defense mechanism. The caterpillar also resembles bird droppings which helps it prevent being eaten. Great photo.
