Pollinated - Moths and Bumblebees. Hadena ectypa, a nocturnal moth tends to be the main pollinator
Nectar - For Butterflies and moths and possibly hummingbirds. Hummingbirds flutter about our nursery all summer long, however we have not observed them visiting Silene stellata. Of course that doesn't mean they didn't.
Deer - Starry Campion contains saponins, a chemical found in the non native plant
Soapwort (Saponaria officinalis) which can be used to make soap. One would expect deer to avoid Starry Campion as both plants are in the Caryophyllaceae family. Illinois Wildflower site reports differently.
