Distributed widely across North, Central, and South America, as well as the Caribbean, these insects possess an incredible life cycle tied closely to their host plants.

While most species are harmless, well-behaved components of their native ecosystems, a few have gained notoriety among farmers as agricultural pests due to their appetite for commercial crops like maize and various legumes.
