Now, since much of Costa Rica is preserved natural jungle, it has some of the best insect and wild animal viewing in the world. For many of our travelers, their experience with large insects and wild animals was limited to cockroaches and city rats. So of course they're grossed out. I have to say it all changes when an expert guide shows you the complexity if an ant colony, the natural defense mechanism of the owl faced butterfly, the hard shell of a centipede, and the brilliant green of a giant grasshopper. The freaky become fascinating. And the squirrel monkeys? They're so cute and funny, it's as if Costa Rica Tourism has them on payroll.
