About the Ghost Ant
Tapinoma melanocephalum is a species of ant that goes by the common name ghost ant. They are recognised by their dark head and pale or translucent legs and gaster (abdomen). This colouring makes this tiny ant seem even smaller.
The ghost ant is small, with average worker lengths ranging between 1.3 to 2.0 millimetres (0.051 to 0.079 in). The antennae is composed of 12 segments that thicken towards the tip. The male's head and dorsum is dark in color, while the gaster is light. It may contain several dark marks. The antennal scapes exceeds the occipital border. The head and thorax is a dark brown color while the gaster, legs and antennae are a milky white color. Due to its small size and light colour, the ghost ant is difficult to see. Ghost ants are monomorphic and the thorax is spineless. The gaster is hairless, and has a back opening that is similar to a slit-like opening. The abdominal pedicel is formed from a single segment that is usually not visible due to the gaster. The species does not contain a stinger. During development, this species undergoes three larval instars, which are all naked and fusiform, with reduced mouthparts.
