The head is 2.2 mm (0.087 in) long and 1.95 millimetres (0.077 in) wide, with the eyes alone measuring 0.66 millimetres (0.026 in). The vertex is covered in sparse pilosity with 0.2 millimetres (0.0079 in) setae. Ocelli are present on top of the ants' head, precisely located just above the dorsal tangent. [14]
The ghost ant is small, with average lengths ranging between 1.3 to 2.0 millimetres (0.051 to 0.079 in) in workers. [2] The antennae composes of 12 segments that thickens towards the tip. [3] The antennal scapes exceeds the occipital border. The head and thorax is a dark brown colour while the gaster, legs and antennae are a milky white colour.
An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. [43]
Ants – social insects with geniculate (elbowed) antennae and a distinctive node-like structure that forms a slender waist. Ants are of the family Formicidae and evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago, diversifying after the rise of flowering plants.
A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae . Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.

The structure of the petiole is an easy way to visually classify ants, because the major subfamilies of Formicidae have structural differences: some ants have two-segmented petioles, while others have a single-segmented petiole. [4] [page needed] Certain wasps also possess a two-segmented petiole, notably extant wasps of the family ...
The head capsule bears most of the sensory organs, including the antennae, ocelli, and compound eyes, along with the mouthparts. In the adult insect, the head capsule appears unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific ...
