There are many types of butterflies native to the United States. Most of them are multicolored but some are dominated by a single color.
The US is home to thousands of species of butterflies, each with its visual characteristics. You can find many brown butterflies or butterflies that are mainly brown in various parts of the US.
Brown can be a color butterflies adapt to according to their environment for camouflage. But it can also be a result of evolution as each species has distinct coloring and patterns on the wings.
The following species of brown butterflies are the most likely to be seen across the US.
