Grasses are some of my favorite plants. I love the way they sway in the breeze and catch the light. When ripe and warmed by the sun they smell like autumn. This is Big Bluestem. It is also known as Turkey Foot Grass because the ripe seed heads look like upside-down turkey feet. This photo was taken at Campbell Prairie, which is in the Oak Openings Metro park.
Hidden in the same prairie is this Praying Mantis egg case. It is very hard, but light - like Styrofoam. The case provides insulation and allows the eggs (and the species) to survive the winter.
