<p>Sampling design and microhabitat characterization of <i>Atta</i> colonies in Santander, Colombia.</p>

<p>(A) Morphological detail of an <i>A. cephalotes</i> soldier. (B) Morphological detail of an <i>A. laevigata</i> soldier. Both depicted individuals were collected from colonies situated in the “La Siberia” location (geographic coordinates in <a href="plosone.org/article/info:doi/10.1371/journal.pone.0351518#pone.0351518.s002" target="_blank">S1 Table</a>; each small square = 1 mm).

(C) Topographic distribution of sampled colonies; markers represent individual nest locations with proportional pie charts indicating species composition at each site, where green represents <i>A. cephalotes</i> and orange with a diagonal hatch pattern represents <i>A. laevigata</i>. (D) Representative canopy cover of a typical <i>A. cephalotes</i> microhabitat; the selected image corresponds to a site with a canopy openness percentage (indicated in panel) approximating the mean estimate for the species.
