When you picture a butterfly garden, you probably envision big, colorful flowers. But did you know that over 100 butterfly species in Texas use native grasses and sedges as their larval host plants? In this episode, Leah makes the case for adding grasses to your pollinator garden.

The majority of grass-obligate butterflies – skippers and satyrs—are small, brown, and understudied. Leah argues that our aesthetic preference for the “charismatic megafauna” of the world of Lepidoptera has created a blind spot for conservationists and gardeners alike, and this spells bad news for little brown butterflies. This leads us down a philosophical rabbit hole, so we bring in rhetorician Eric Dieter (Colleen’s husband) to discuss the role of aesthetic biases, gaps in scholarly literature, and data collection in contributing to the problem of ecological “unknown unknowns.” 

Then we talk about one researcher who is studying this topic, Diane Narem, and cover her recommendations for using native grasses and sedges to support a more diverse butterfly habitat.
