Which came first, the moth or the cactus?
...rthern Mexico, the senita moth depends on a single plant
species -- the senita cactus -- both for its food and for a place to lay eggs. The senita cactus is equally dependent upon the moth, the only species that pollinates its flowers. Senita cacti and senita moths have a rare, mutually dependent relations...

Lost forest yields several new species
