Are white grubs the immature stage of a brown beetle that is common at porch lights during spring evenings?

White grubs are indeed the larval or immature stage of several species of beetles, including the commonly known June beetles or May beetles, which are brown and often found around porch lights in spring. As these adult beetles emerge in the spring, they are likely to be attracted to lights, making their presence noticeable during that time. The lifecycle of these beetles includes the transformation from the grub stage in the soil to the adult stage that is seen flying around lights, confirming that the statement about white grubs relates to a brown beetle commonly observed during spring evenings is accurate. This understanding of the lifecycle is crucial for pest management in lawn and ornamental settings, as identifying and targeting the correct life stage of a pest leads to more effective control strategies.
