Banded sugar ant 20 cm (8 in) in diameter and usually funnel-shaped and ephemeral. Mounds are not constructed in undisturbed regions where land degradation has not occurred. Instead, the entrance of a nest consists of a smooth-walled vertical shaft that is in diameter. Chambers in the nest have a similar appearance to the nest entrance (shaft-like walls), and the floors within the chambers are typically in length with an arched roof that is in height. Excavated meat ant nests show that banded sugar ants will also inhabit them. Banded sugar ants are the dominant group of nocturnal ants in their range. Workers are
Myrmecia (ant) lack of food during winter and they could be incipient colonies. The division of labour is based on the size of ant, rather than its age, with the larger workers foraging for food or keeping guard outside the nest, while the smaller workers tend to the brood. Their colouration is variable; black combined with red and yellow is a common pattern, and many species have golden-coloured pubescence (hair). Many other species are brightly coloured, which warns predators to avoid them. The formicine ant "Camponotus bendigensis" is similar in appearance to "M. fulvipes", and data suggest "C. bengdigensis" is a batesian
