Etymology
editThe generic name Cyclocephala means "round head".[2]
Ecology
editPollination
editFlowers of Nymphaea subg. Hydrocallis are pollinated by Cyclocephala beetles.[5][6] Likewise, flowers of Victoria are pollinated by Cyclocephala.[7]
Predation
editSeveral species of Cyclocephala serve as hosts for the parasitic larvae of the South American robber fly Mallophora ruficauda, especially C. signaticollis.[8]
Herbivory
editThe larvae are root feeders.[2]
