Acanthepeira stellata, star bellied orbweaver spiders, were seldom found during surveys at Barnes Prairie, a group of tallgrass prairie remnants in Racine Co. WI. Surveys were conducted from 1990-2022. When found, they were in the same grassy area with common milkweed, azure aster, sneezeweed, common yarrow, and scattered goldenrod species. All spiders seen had webs on grass leaves and stems.
