**May Beetles** (genus *Phyllophaga*), also commonly known as **June Bugs** or **June Beetles**, are large, clumsy scarab beetles common in temperate regions. The adults are nocturnal pests that feed on the foliage of deciduous trees and shrubs, causing minor defoliation. However, the most significant conflict comes from their larvae, known as **white grubs** (Lawn Grubs), which live underground for one to three years, feeding voraciously on the roots of grasses and crops, causing widespread damage to lawns, pastures, and agricultural fields.
Taxonomy and Classification
May Beetles belong to the order Coleoptera, family Scarabaeidae. They undergo complete metamorphosis, often having a life cycle lasting two or three years. They are called May or June Beetles because the adults typically emerge from the soil in these months. Their characteristic clumsy flight is often accompanied by a loud buzzing sound.
Physical Description
Adult May Beetles are stout, oval-shaped, shiny reddish-brown or dark brown, $1/2$ to $1$ inch long.
- **Adult (Key ID):** C-shaped antennae with a small, leaf-like club at the tip. They are attracted to lights at night and often fly clumsily into windows or screens.
