National Butterfly Center
Tropical Trail Region
Did you know nearly 150 species of North American butterflies can be seen only in the Lower Rio Grande Valley (LRGV) of Texas, or by traveling to Mexico? In fact, more than 300 species of butterflies may be found in the LRGV, and more than 200 species have been seen at the National Butterfly Center, including a number of rarities and U.S. Records! Incredibly, almost 40% of the 700+ butterflies that can be found in the United States can be seen in this three-county area at the southernmost tip of Texas, where the subtropical climate makes it possible to enjoy the outdoors year 'round.
