Stenamma Ants

Official Name

Leaf-Litter

Size

2 to 3 mm

Color

Light Brown through Reddish Brown to almost Black but never Black

Geographical Location

Found in Europe, Northern Africa (Morocco and Algeria), Temperate Asia, and Japan.

Common Household Location

Lawn, Garden and Kitchen

Identifying Characteristics

  • Stenamma is closely related to the genera Aphaenogaster and Messor.The most notable difference is the structure of the clypeus. In both Aphaenogaster and Messor, the posteromedial portion of the clypeus is broadly inserted between the frontal lobes and when looked at in full-face view is generally much wider than either lobe at the broadest point.

Notes

Stenamma is a cryptic “leaf-litter” ant genus that occurs in mesic forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus was thought to be restricted primarily to the temperate zone, but recent collecting efforts have uncovered a large radiation of Neotropical forms, which rival the Holarctic species in terms of morphological and behavioral diversity
