Tank Army Ants

Official Name

Nomamyrmex

Size

15-23 mm

Color

Bright Red Color

Geographical Location

Found in South Texas to Northern Argentina

Common Household Location

Kitchen, Lawn and Room

Identifying Characteristics

  • The workers of Nomamyrmex are easily recognized by a combination of highly positioned spiracle and lack of pronounced propodeal lobes, propodeum armed with cuticular projections, two-segmented waist, armed pretarsal claws, and absence of metatibial gland. The lack of conspicuous lighter area of cuticle on the inner side of hind tibia (the metatibial gland) distinguishes this genus from all other Eciton genus-group ants except for some Neivamyrmex, but those always have simple pretarsal claws.
  • Male Nomamyrmex males possess traits characteristic of New World army ants.

Notes

Nomamyrmex is the most heavily armored of the army ants. This genus is found from south Texas to northern Argentina. Like all army ants it is nomadic, without permanent nests. Nomamyrmex preys on the brood of other ant species, and is the only ant that attacks mature colonies of Atta leafcutters.
