Blue Morphos tend to live in group. Their lifespan is less than 4 months. Living in close proximity helps maintain a population and provides single butterflies instant assistance in distracting predators with their many eyespots and flickers of cobalt blue. Caterpillars are reddish brown and black with large spots of yellow on them. The head, underbelly and rear are covered with tufts of stinging white and brown hairs. Caterpillars eat the leaves of clover and legumes found in the Pea plant family. Adults drink the juices of spoiling tropical fruits. Some of these juices may have started fermenting as they rot, producing an alcohol by-product which may make the butterflies slightly inebriated as they feed.
