Butterflies (Lepidoptera2)
The information for the butterflies came from the Butterflies of Iowa book by Dennis Schlicht. Dennis and the University of Iowa Press gave me permission to use the information. The monthly graph, year to year graph, the Midwest region and the Iowa map are generated from the records in the database.
