We have a new article on Featured Creatures that will answer that question!
Take a sneak peek with this excerpt from the article: Morpho peleides Kollar, the blue morpho butterfly, also known as the peleides blue morpho or common blue morpho, is a brightly colored butterfly abundant in tropical environments in Central and South America (Figure 1). It can be seen flying in open areas such as paths, trails, forest edges, and rivers, and avoiding dense forest (Young 1973).
This butterfly is often featured in museums and zoos having butterfly houses or butterfly rainforests in the United States.
