From 2002 to 2007, participants attempted to verify the presence of as many species of butterfly as possible within spatially defined atlas blocks across the state, noting a variety of other data with each record. Atlas blocks were based on USGS topographic quadrangles. Each quad was divided into six equal blocks for a total of 1,104 blocks of approximately three square miles each. The result is the most detailed database of the spatial and seasonal distribution of Vermont butterflies ever compiled. The atlas is scheduled to be repeated every 25 years.
