Nesting Biology

Nests are usually found in aggregations of 5–65 nests per square meter in flat ground or small banks in very hard soils in open, barren areas. Nest entrances lack turrets and cells are arranged in linear series. 

Adults of A. walteri fly from about October at least through July. Presumably immature spend most of the year as postdefecating larvae and the period of adult emergence corresponds with blooming of S. bogotensis and the second peak of maximum rain in October.
