Cyclocephala lurida

Definition

A species of scarab beetle (family Scarabaeidae) native to the southeastern United States, commonly known as the southern masked chafer. Adults are small (10–14 mm), brown with a black head, and non-damaging; the subterranean larval stage feeds on grass roots and can cause significant turf damage under dry conditions, making it a pest of lawns and golf courses.

Etymology

Latin luridus meaning 'pale yellow' or 'ghastly,' likely referring to the beetle's coloration.

Example

Cyclocephala lurida larvae are classic white grubs that can be distinguished from other turf pests by their raster pattern and the timing of adult emergence in late spring.

Synonyms

• southern masked chafer

Usage Notes

The species epithet is sometimes misspelled luridus; the original combination by Bland (1863) established lurida. Two subspecies are recognized: C. l. lurida and C. l. coahuilae. Adults are nocturnal and attracted to light; they do not feed, living on fat reserves accumulated as larvae.
