Longino (2007) - The taxonomy and biology of A. constructor are reviewed in Longino (1989b, 1991a, b). The species is an obligate Cecropia ant. It inhabits a broad range of habitats and elevations. It is often associated with forest gaps or edges where there are relatively larger and older Cecropia trees. Mature colonies occupy a single carton nest in the bole of the tree. The nest is spindle-shaped and causes a deformation of the trunk. All larvae and alate sexuals are concentrated in this single nest. Branch tips, which all communicate internally with the carton nest, contain only workers and Hemiptera. Workers of this species are extremely aggressive, and respond to any disturbance by pouring out of large fissures near the carton nest and blackening the trunk surface (Longino 1991a).
Longino (2007) - The queens of A. constructor are very distinctive and not easily confused with any other species. Workers of A. constructor and Azteca xanthochroa are very similar. Large workers of A. constructor retain a chocolate brown color, while large workers of A. xanthochroa become more mottled orange. The petiolar node of A. constructor workers is relatively low, while the posteroventral lobe is relatively deep and strongly convex. Workers of A. xanthochroa are the reverse, with relatively taller node and shallower ventral lobe.

|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.|
|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.|
Longino (2007) - Alate queens of this species and another common Cecropia ant, A. xanthochroa, are relatively common in Malaise trap samples from the Atlantic slope rainforests of Costa Rica. No other Azteca species are common in Malaise traps, even though they are common in the environment. Even the other common Cecropia ants, Azteca alfari and Azteca ovaticeps, are not common in Malaise samples. This implies that there is something distinctive about the behavior of queens of these two species that makes them more susceptible to capture.
