Specimen Labels

A common species typically found in drier areas, C. ionius has been found in a range of habitats (see distribution section below). Nests have been uncovered by turning over large stones. Workers are usually active at dawn and dusk. Major workers forage up to 10 meters away from the nest and are often collected on roads or tree trunks.


A member of the Camponotus samius species complex (Tanaemyrmex).

Salata et al. (2020) - Hind tibia and scape with decumbent to suberect pilosity but without additional erect setae; gena without numerous erect setae; mesosoma in major workers sometimes ventrolaterally paler (brown to bright brown) than black to dark brown head and gaster, in minor workers mesosoma usually slightly paler than head and gaster, with dark dorsum and brown to bright brown lateral sides; legs in minor and major workers reddish brown; gaster in major and minor workers uniformly coloured, sometimes minor with indistinctly brighter colouration on its basal part; pilosity on gaster sparse.

This species has been found in various types of arid habitats. Camponotus ionius has most commonly been collected from pine forests, but also observed in olive plantations, deciduous forests, and gardens in urban areas. Workers are also occasionally observed in open habitats, especially pastures with shrubs and limestone rocks or large stones. Camponotus ionius is also one of the pioneer species in burned forests.
