The presence of the metapleural gland, the nodiform (a structure resembling a node, which is a segment found between the mesosoma and gaster, the bulbous posterior portion of the metasoma), the structure of the petiole and its general physical appearance of an ant concludes Sphecomyrma species are ants rather than wasps; the absence of the ...
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 ...
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]
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 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.

It holds the head, legs, wings and abdomen. It is also called mesosoma or cephalothorax in other arthropods. It is formed by the prothorax , mesothorax and metathorax and comprises the scutellum ; the cervix , a membrane that separates the head from the thorax; and the pleuron , a lateral sclerite of the thorax.
A. sexdens follows the basic body plan of ants fairly closely. They have sharp spikes or hooks rising from their heads and midsections to deter predators. Another distinguishing feature is a relatively large, two-lobed head. Its purpose is to accommodate the large muscles moving the well-developed mandibles. [citation needed]
