In a habitat that would be deadly to most other insects, the freezing temperatures high on the slopes of Cotopaxi volcano in Ecuador are home to a very unusual walkingstick: Monticomorpha flavolimbata. Feeding on páramo vegetation that is frequently crusted over with frost, this species has been recorded at altitudes of up to 5000m, making it the highest elevation known for any stick insect. Presumably its dark coloration helps it to more efficiently absorb the suns fleeting warmth.
