Macromia illinoiensis illinoiensis
Illinois River Cruiser
A subspecies of river cruiser dragonfly whose larvae are frequently colonized by invasive zebra mussels (Dreissena polymorpha).

Research indicates zebra mussel attachment negatively affects prey capture rates and alters burying depth, with behavioral changes reversing upon natural mussel loss at molting.
