Interactions in Native Habitat
In South America, Cactoblastis cactorum has many natural predators, including ants and New World monkeys. Ants, the moth's main predators, consume its larvae. New World monkeys hollow out the larvae and pupae from the flattened leaf-like stems, or "cladodes", of the cacti. The relationship between Cactoblastis cactorum and Opuntia cactus species is parasitic: the moth feeds on the host cactus. In South America, it feeds on all Opuntia cactus species, with few exceptions (Opuntia sulphurea, Opuntia pampeana, Opuntia quimilo and others). Unlike other Cactoblastis species, Cactoblastis cactorum is not host-specific. Outside of these interactions, much of the moth’s relationship within its South American habitat is unexplored.

Famous quotes containing the words interactions, native and/or habitat:
“The exercise of power is determined by thousands of interactions between the world of the powerful and that of the powerless, all the more so because these worlds are never divided by a sharp line: everyone has a small part of himself in both.”
—Václav Havel (b. 1936)
“In excited conversation we have glimpses of the universe, hints of power native to the soul, far-darting lights and shadows of an Andes landscape, such as we can hardly attain in lone meditation. Here are oracles sometimes profusely given, to which the memory goes back in barren hours.”
—Ralph Waldo Emerson (18031882)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (18421910)
