What is the typical length range for worker Anoplolepis gracilipes individuals?

Between 2 and 3 millimeters in length

Worker ants identified as *Anoplolepis gracilipes* generally fall within a small size range, specifically noted as measuring between 2 and 3 millimeters. While some measurements might push the upper limit slightly beyond 3 millimeters, the core observed range for the workers is established within this 2 to 3 millimeter spectrum. This small size is a critical characteristic that, combined with other features, helps differentiate them from many other species found in disturbed environments. The small stature means that in isolation, a single ant can be easily missed, especially given their rapid movement patterns.
