As in other lampsilines, the female uses mantel lure flaps resembling prey fish to attract piscivorous fish that are hosts for glochidia. On contact with the flaps, the fish ruptures the mussel's marsupial gills, thereby releasing the glochidia into the surrounding water and serving as a landing site for the glochidia. Females have been observed in a head stand position while waving their mantel flaps, and this mantel lure display may take place from July through September when breeding is finished. The only known suitable fish hosts are smallmouth bass "Micropterus dolomieu" and largemouth bass "M. salmoides"; although spotted bass "M. punctulatus" has been proposed as another suitable host.
