Cyclocephala

Se systematisk inndeling

Cyclocephala er en artsrik slekt av biller som hører til gruppen hornbiller i familien skarabider (Scarabaeidae).

Utseende 
Middelsstore (7-25 millimeter), avlange, blanke, brungule, rødlige eller mørke biller. Mange arter har mørke fargetegninger, de kan også være ensfarget mørke. De er blant de minste hornbillene og mangler horn. Et særtrekk er at de vifteformede antennene bare har to «vifteblader».

Levevis 
De voksne billene er nattaktive og kommer til lys. I alle fall noen arter besøker blomster (for eksempel på planter i myrkonglefamilien) og kan være viktige pollinatorer. Larvene er kjent bare for et fåtall av artene, disse lever i jorda og eter på gressrøtter.

Utbredelse 
Artene er utbredt i Nord-Amerika, der de kan være meget tallrike, men de aller fleste lever i Sør- og Mellom-Amerika.

Systematisk inndeling 
Avgrensingen av slekten er noe uklar, spesielt er den ofte vanskelig å skille fra slekten Aspidolea.
