Distribution
Diarrhena americana naturally occurs throughout the mid-east part of the United States. it ranges from Oklahoma to the east coast, and can even be seen as far north as Michigan.[4] Even though there is a rather large range in the United States, Diarrhena americana is now considered a distinct species with a more northern range, where much of the population is seen in southern Illinois.[5]
