Natural History:

This species is extremely rare and nothing is known of its biology. Brown (1978) reported museum specimens from scattered localities in South America, stating it was relatively rare in collections. Three workers are known from Costa Rica, all from one fogging sample. The specimens came from one of the Project ALAS fogging samples, a Minquartia guianensis tree (Olacaceae), from La Selva Biological Station in the Atlantic lowlands.

It is curious how a species, especially one this large, can be so rare in collections. In spite of much myrmecological work in Central America in the past century, and an intensive inventory of ants at La Selva, only the three workers have been encountered. Over 50 trees have been fogged at La Selva, and A. bispinosus occurred in only one. Perhaps there is some aspect of its nesting biology that makes it difficult to sample.
