Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.


While this species is known to nest in ant gardens it does not seem to be a true ant-garden taxon (i.e., one that is able to initiate ant gardens or is restricted to ant gardens) and is more likely to be a secondary resident or opportunistic ant-garden nester (Benzing & Clements, 1991; Campbell et al., 2022; Kleijn & Van Donkelaar, 2001).
