Caterpillars in Colombia
Caterpillars are the larval form of moths and butterflies. Since these creatures are so rich in protein, they tend to be a favored food source of many species. As a result, caterpillars have developed many a coping mechanism for this issue. Predators can easily be deterred by the appearance or size of a caterpillar. Bright colors, as seen in these pictures, usually makes an animal think poison, so they will tend to stay away. While some caterpillars may fake it, there are indeed some truly poisonous caterpillars out there as well. Also, spikes make a good predator deterrent because of the lack of appeal they present to being eaten.
