Which statement correctly describes the leg count in billbug and white grub larvae?

• A. Billbug larvae have legs; white grubs have six
• B. Billbug larvae have no legs; white grubs have six
• C. Billbug larvae have six legs; white grubs have none
• D. Billbug larvae have no legs; white grubs have no legs

Answer: (B)

Understanding how these larvae look helps you tell them apart. Billbug larvae are the larval stage of weevils and are typically legless, smooth grubs living in plant tissue. White grubs, which are scarab beetle larvae, have six legs near the front that they use to move through the soil while feeding on roots. So the correct description is that billbug larvae have no legs and white grubs have six. This matches what you’d expect from their insect groups, while other statements mix up these traits and don’t fit what these pests look like.
