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.[1]

Description

The ghost ant is small, with average lengths ranging between 1.3 to 2.0 millimetres (0.051 to 0.079 in) in workers.

monomorphic and the thorax is spineless.[2] The gaster is hairless, and has a back opening that is similar to a slit-like opening.[3] The abdominal pedicel is formed from a single segment that is usually unable to be seen due to the gaster, and the species do not contain a stinger.[2] During development, this species undergoes three larval instars, which are all naked and fusiform, with reduced mouthparts.[4]

The queens are similar in appearance to a worker, but the alitrunk (

dorsum is dark in colour, while the gaster is light. It may contain several dark marks. They are usually 2.0 millimetres (0.079 in) in length.[1]

Distribution and habitat

Due to how widespread the ghost ant is, the exact native range is not exactly known.

Galapagos Islands.[8] The ant is found in 154 geographical areas.[9]

The species is a common pest in the United States, particularly in the states of Hawaii and Florida, although the species is expanding further north, even reaching Texas by the mid 1990s.[10] They are commonly found in the southern parts of Florida, and is considered a key pest, along with several other invasive ant species.[11] The earliest record of the ghost ant in the United States was in 1887, where the species was found in Hawaii.[12] It was then recorded in Washington, D.C. in 1894.[13] After these two records, the ghost ant would later be found in Maine, New York, Connecticut, Virginia, North Carolina, Georgia, Florida, Illinois, Michigan, Wisconsin, Minnesota, Iowa, Missouri, Louisiana, Texas, Kansas, New Mexico, Arizona, California, Oregon and Washington.[9][14] Ghost ants can be found in the U.S. territories of Puerto Rico and the U.S. Virgin Islands.[15]
