Larva mouth-parts like their adult but labium modified as extensible grasping organ. These apical lobes are thought to be derived from the insect’s labial palps. That is how they survive. Immature stages of many holometabolous insects (like beetle larvae and lepidopteran caterpillars also have mandibulate mouthparts. The maxillae and labium interlock to form a hinged proboscis that can be extended from beneath the head to lap up nectar. Termites are actually social cockroaches. They have overlapping edges that cut like scissors and molar surfaces for grinding or crushing. Oesophagus is short, narrow and tubular and connects the mouth with the crop.

The mouth parts consist of a labrum (upper lip), a pair of mandibles, a pair of maxillae and a labium (lower lip). However, twig girdler damage can be significant, especially in pecan, hickory and oak trees. The labrum is relatively short and close to the head capsule.
