Table 1.
Size of the territories of nine Daceton armigerum colonies and the estimated number of individuals.
Figure 1.
Different levels of aggressiveness noted on the part of Daceton armigerum guards towards workers.
They originated from the same tree (same tree tests), a different tree belonging to the same patch thought to belong to the territory of the same D. armigerum colony (intra-patch tests), and two different patches (inter-patch tests). The introduced worker is another Daceton armigerum (a), an Azteca sp. pittieri complex (b), a Crematogaster carinata (c) and a Dolichoderus bispinosus (d). Statistical comparisons: Chi-square tests and sequential Bonferroni correction; different letters above the plots indicate significant differences (P<0.001 for a and c; P<0.05 for b; N = 25 in all cases).

Associations between the most frequent species (relative frequency >5%) from the Awala-Yalimapo transect.
Figure 2.
Rhythm of activity of Daceton armigerum workers.
A. The workers were noted entering or leaving their nests (the study was conducted in a garden in Kourou over the entire nycthemeron). B. Activity in the foraging areas (the study was conducted in the field).
Figure 3.
An ambushing Daceton armigerum worker that just seized a pierid butterfly after striking it on the head with its long mandibles.
This numbed the butterfly at first, but it later struggled and was then spread-eagled by six recruited workers. One can note the well-developed claws on the pretarsa, at the extremities of the worker's legs, permitting it to get a good grip on the bark of the host tree.
