What is the common name for the adult form of white grubs?

The adult form of white grubs is commonly known as the June Bug. White grubs are the larval stage of various beetles, and specifically, they are often the larvae of the scarab family, which includes the June Bug. This beetle emerges in the warmer months, typically in June, hence the name. June Bugs are large, often shiny, and can be found flying around at night as they are attracted to lights. Their lifecycle begins with the female laying eggs in the soil, which hatch into grubs that feed on organic matter and plant roots, potentially causing damage to lawns and gardens.

The other options are not associated with the larval stage of white grubs. The Carpenter Bee is a solitary bee known for boring holes in wood and does not have a connection to white grubs. A Wireworm is the larval form of click beetles and is also unrelated to the white grub lifecycle. Meanwhile, Flea Beetles are small jumping beetles that primarily feed on various plants, and do not relate to grubs in any form. Therefore, the association of the June Bug with white grubs is accurate in the context of their life cycle.
