Beetle larvae

Beetle larvae are the prepubescent form of beetles. They are commonly referred to as grubs.

Feathered Dragons
A beetle grub hiding within a tree was dug up by an Epidexipteryx but was then stolen and eaten by a larger individual. Later, the smaller Epidexipteryx dug up another beetle grub but accidentally dropped onto the forest floor. The larger Epidexipteryx climbed down to eat it seconds before being eaten itself by a juvenile Sinraptor.
