Dr. Jeffrey Glassberg, president and founder of the North American Butterfly Association, told me when we first met that butterflies were like the canary in the coal mine when it came to our ecosystem. A healthy butterfly population, one where new generations are constantly being created, speaks volumes for the overall health of the local environment.
I saw that firsthand as the director of the National Butterfly Center in Mission, Texas. This 100-acre property owned by the North American Butterfly Association is on the Lower Rio Grande River, right across from Mexico. Here, native plants are arranged in gardens providing everything to not only attract but sustain the life of butterflies.
Well over 200 species have been identified right there, which is quite an accomplishment when you consider most states in their entirety have far less. An example is Georgia where I live now; it has documented 160 species of butterflies. The larger lesson taught at the National Butterfly Center was that when you start providing for butterflies, your whole localized ecosystem seems to change.
I feel I was able to see this at the Columbus Botanical Garden and the Coastal Georgia Botanical Gardens in Savannah where I later served as director. Birds who eat bugs, including your butterflies, and those who eat the seeds from plants you grow show up, while at the same time hummingbirds start to frequent many of the flowers while also carrying on pollination. Dragonflies, the arch-enemy of butterflies, proliferate as well.
