The flowers attract few insects because they are wind-pollinated. The caterpillars of the butterfly Enodia anthedon
(Northern Pearly Eye) feed on the foliage of Inland Oats, as do the caterpillars of several Amblyscirtes spp.
(Roadside Skippers), including Amblyscirtes vialis
(Common Roadside Skipper), Amblyscirtes linda
(Linda's Roadside Skipper), and Amblyscirtes belli
(Bell's Roadside Skipper). The latter two skippers are restricted to southern Illinois and neighboring areas, where their preferred food plant, Inland Oats, is more common.
