Summary

Cyclocephala is a diverse genus of scarab beetles known for their nocturnal behavior and root-feeding larval stages. They span a wide geographic range and some species can be agricultural pests due to larval feeding habits.

Physical Characteristics

Adults are nocturnal or crepuscular with a body shape similar to many Phyllophaga species.

Identification Tips

Cyclocephala can be differentiated from similar genera by specific morphological characters; consult local keys for species identification.

Habitat

Primarily found in tropical regions; they inhabit areas where they can access root systems.

Distribution

From southeastern Canada to Argentina, India, and the West Indies.

Diet

Larvae are root feeders, potentially causing damage to crops.

Life Cycle

Life cycle data is limited; adults are often attracted to lights for mating and feeding.

Predators

Hosts for parasitic larvae of the South American robber fly Mallophora ruficauda, particularly C. signaticollis.

Ecosystem Role

As root feeders, they play a role in soil aeration and nutrient cycling, but can also be agricultural pests.

Economic Impact

Some species can damage crops due to their larval feeding habits.

Collecting Methods

  • Light trapping
  • Soil sampling to find larvae

Preservation Methods

  • Pinning adults
  • Alcohol preservation for larvae

Evolution

Cyclocephala is one of the largest genera within the Dynastinae subfamily, with ongoing descriptions of new species.

Similar Taxa

Misconceptions
