''Pheidole fervens'' is a species of ants in the subfamily Myrmicinae. ''Pheidole fervens'', described from Singapore, is a widespread invasive species and could be native to the Oriental or the Oceanic region.〔 ==Habitat and distribution== It usually nests in soil or under stones and usually prefers disturbed habitats. On Fiji it was collected in elevations between 1–800 m and tended to inhabit several different habitats from forest edge and mangrove forest to disturbed and undisturbed rainforest. On Mauritius, which seems to be its western distribution limit, this ant was found in the leaf litter of lowland rainforest (200 m elevation). As with most other introduced ants, such as ''P. teneriffana'', it is unclear what effect, if any, ''P. fervens'' might have on the rest of the local ant fauna. Considering that the ecosystems of the Mauritius islands have been severely altered and disturbed since the arrival of human settlers several hundred years ago, and native species must also contend with the invasions of introduced organisms, parts of the original ant fauna might have been marginalized or driven to extinction long ago. Fischer & Fisher (2013) speculate that the scarcity of ''P. fervens'' specimens in Mauritius ant collections and its presence in the rainforest means that this ant has not yet become an invasive and dominant aggressor toward other ant species. Nevertheless, efforts to further investigate the presence and activity of introduced ''Pheidole'' species are worthwhile, especially in the few remaining undisturbed habitats.〔
