Are grubs the larvae of Japanese beetles?

White grubs are the larval or grub stage of several species of beetles and chafers. The two most troublesome species in New Hampshire are the European chafer (Rhizotrogus majalis)and the Japanese beetle (Popillia japonica). These beetle larvae are usually C-shaped and can be found feeding among grass roots.

Where do Japanese beetles lay their larvae?

The eggs are white and oval and laid in the soil about 2 to 4 inches down where they can absorb moisture. Female Japanese beetles will leave the plant that they are feeding on to find ideal conditions and soil to lay eggs in. The females will lay anywhere between 1 to 5 eggs throughout the area that they choose.

How many instars does a Japanese Beetle have?

The eggs will develop into grubs and can spend the fall and winter months in the ground developing toward the pupation stage and ultimately into the adult. The larvae are typical white grubs and go through 5 instars, or molts, before pupating into the adult form.

How long does it take for Japanese Beetle eggs to hatch?

The eggs hatch in about two weeks and the grubs feed mainly on the roots of lawn grasses. Grubs go through three different growth stages (instars) during the summer becoming progressively larger with each stage.

When do Japanese beetle pupae leave the ground?

The pupae are cream to reddish brown in color and are 1/2 inch wide. Once the larva or grubs are fully developed they enter the pupation stage and become adults. Once the adult stage is reached in the early part of the summer months, they leave the ground and immediately begin to look for plants to feed on.
