White-Footed Ants

Official Name

Technomyrmex

Size

3 mm

Color

White-footed ant is Dark in color, with Light Yellow or Yellowish-White Tarsi

Geographical Location

Found in Wellington and Manawatu regions

Common Household Location

Attracted towards Sweet foods within the home.

Identifying Characteristics

  • This small ant is easily confused with Crazy ants and Odorous House Ants if not properly identified. Although the body of the white-footed ant closely resembles that of the crazy ant, its legs and first segment of its antennae are much shorter. This ant's body color is darker than that of the odorous house ant. The white-footed ant (which has one node) has one distinguishing characteristic which sets apart from similar ants: the tarsi (section at the end of the legs) are a very light yellow or yellowish white in color. This gives it the appearance of having "white feet," hence its name.

Notes

White-footed ants prefer sweet foods and dead insects (such as termites and cockroaches), but will also feast on tree and flower nectar’s. The heaviest concentration of foraging white-footed ants occurs at night during the summer.

An interesting fact about white-footed ants is that the workers do not regurgitate food to share with other ants in the colony, as do most ant species. Instead, the workers lay unfertilised eggs which they feed to other ants in the colony that are not active foragers. What this means for pest control is that baiting is not effective with white-footed ants. Since white-footed ants do not share food, toxic baits affect only those ants that directly ingest it rather than being shared and spread throughout the colony.
