Cyclocephala is a genus of scarab beetles from the subfamily Dynastinae (Coleoptera, Scarabaeidae). Beetles of this genus occur from southeastern Canada to Argentina, India and the West Indies.

Adults of this genus are nocturnal or crepuscular, and are usually attracted to lights.

Ecology

Pollination

Flowers of Nymphaea subg. Hydrocallis are pollinated by Cyclocephala beetles. Likewise, flowers of Victoria are pollinated by Cyclocephala.

Predation

Several species of Cyclocephala serve as hosts for the parasitic larvae of the South American robber fly Mallophora ruficauda, especially C. signaticollis.

Herbivory

The larvae are root feeders.
