Cup plant adds more color to the prairie

For several day, the cup plants have been popping. Their bright yellow flowers staring at the sun. Each time I look, they are being visited by an assortment of bees, bugs and flies. The plants have sturdy square stems. Their unusual leaves grow around the stem creating an area for water to collect. No water today, it has been a dry week. But it didn't stop this milkweed bug from having a look.
