Frons

Head of a dragonfly (Southern Hawker, Aeshna cyanea) showing the frons.

Frons (singular) is the term used to describe the frontal area of an insect's head. It covers the upper part of the face above the clypeus and below and between the antennae. It supports the pharyngeal dilator muscles and usually bears an ocellus (simple eye). The term itself is derived from the Latin frons "forehead".
